Squash is a kind of pickle that many people have eaten, common in supermarkets, I believe that many people are very curious about how this kind of vegetable is planted, the following is my squash planting method for you, I hope it is useful to you.
Pressure mustard planting methods1, mustard varieties and cultivation plots
(1) varieties to choose: semi-fragmented leaves shrinking head species and Zhetong one, adapted to the processing needs, both processing blocks into products mustard, but also can be shredded processing.
(2) Cultivation plot selection: in line with the requirements of the provincial pollution-free vegetable standard B33/T291.1, to the soil loose and fertile, pH 6.5-7.5, low water table plains or sericulture land sandy loam soil is good.
2, sowing seedlings
At the end of September and early October, staged batch sowing, too early sowing due to high temperatures, heavy virus disease, too late sowing is a short pre-winter growth, small tubers, low yield. The amount of seed sown per acre of field is about 100g, the requirements of seed full, strong germination potential, sowing requirements to do fine sowing, even sowing, general transplanting field and seedbed area ratio can be up to 10 times more than.
Before sowing, the seeds were treated with 10% trisodium phosphate for 10 minutes, and then washed 10 times to blunt the virus and reduce virus damage, or mixed with MnZn diclofenac. Before sowing, the seedling land is fully fertilized, and 50% phoxim 1000 times for soil treatment to eliminate underground pests.
3, seedling management
After sowing, cover the seeds with fine soil and spray the beds with herbicides such as 60% butachlor 100 ml or ethofumesate 50-70 ml before germination, and cover the top with shade nets or other shading, and then uncover in time after the emergence of seedlings.
After the emergence of seedlings in a timely manner to delete seedlings, to go to the poor to miscellaneous, to go to the sick plants, to do each other not crowded seedlings, the second inter-seedling in the pull after the cross, and then every 7 days, generally 2-3 times. Each time after the seedlings in time to apply thin fertilizer, and depending on the weather conditions in a timely manner sprinkled with water to keep moist, it is appropriate to carry out morning and evening.
4, transplanting and planting
The right time to transplant to the seedling age of 40 days, 4 leaves and 1 heart is good, generally in early to mid-November is good, late no more than November 25, such as in the event of a drought transplanting can be ditch irrigation once, not more than the border, to ensure that the press vegetables planted in a timely manner.
5, field management
(1) pre-winter growth period (early)
transplanted in a timely manner to apply a good root fertilizer or in the return of the seedling into the general 667m2 with urea 4 ~ 5kg, plus water 1000kg, the use of pre-winter limited growth period (generally before December 15), so that its leaves thrive to achieve a strong seedling over the winter, the leaf is thick, leaf green, cold resistance is good! .
After returning the seedlings, mu with 60% butachlor emulsion 100-125ml with 50-60kg of water spraying sun beds or ethofumesate 50-75ml with 50-60kg of water spraying, anti-weed.
In case of prolonged drought before winter, the ditch can be irrigated once according to the situation, and drained in time, not full over the border.
The field according to the weather conditions in time to prevent aphids 1 to 2 times, the agent to choose the same seedling land, and timely removal of virus plants to prevent infection.
In winter, if there is too much rain, the ditch should be opened in time to drain the water and do a good job of preventing stains.
(2) field management (mid)
The early stage of tuber expansion, time in mid-January to early February, requires the old healthy leaves, strong resistance.
In late January, the second fertilizer, generally per 667m2 with ammonium carbonate 25kg + calcium superphosphate 20kg + potassium chloride 5kg with 1500kg of water watering, to meet the fertilizer needs of the bulb at the beginning of the expansion period.
According to the winter weather conditions in a timely manner to do a good job of clearing the ditch drainage work, while removing the ditch side of the weeds, in order to prevent weeds and vegetables compete for fertilizer.
Do a good job of cold and frost, in the border of the soil, cover grass, and prevent the partial application of nitrogen fertilizer.
(3) field management (late)
Rumen expansion period, with the rising temperatures, squash growth accelerated, the tumor expansion speed accelerated, in mid-March or so, the requirements of the stem, leaf growth coordination, to reduce the hollow.
In late February, heavy fertilizer, 667m2 with urea 25kg plus 12.5kg of potassium chloride and water, do not withdraw or single application of nitrogen fertilizer, resulting in leaf and tuber burns and other fertilizer damage, every other week, according to the growth situation, and then fertilizer 1, prompting the expansion of the tuber with the growth of the leaves in line with the reduction of hollow, reduce the hollow index.
After the spring of February-March temperatures rise, happen to rain more years, field humidity, high temperature and humidity is easy to cause disease, must seize the time to do a good job of ditching and drainage work.
Pressure cooker planting skills(1) cultivate strong seedling
1, choose a good seed. Processing of squash can choose green waist, three layers, goose buns, loquat leaves and other varieties; if not processed, in addition to the above varieties, you can also choose three rotors, lamb's quarters and so on.
2, land preparation and fertilization. Seedbed should be selected to facilitate drainage and irrigation with sandy soil, requiring each mu seedbed manure 30 quintals, 50 kg of phosphate fertilizer, 20 kg of ammonium carbonate, deep fertilization for base fertilizer, seedbed package ditch 2.5 m compartments, fine soil rectification, sowing each mu with 30?40 quintals of whacked fine soil fertilizer as a cover of seed fertilizer.
3, timely sowing and the amount of seed in the field. Timely sowing is the basis of high yield, through nearly 10 years of practice has proved that the appropriate sowing period for the September 19th a 21st best, early sowing of early moss phenomenon leads to yield reduction. The amount of seed per acre of the field 50?60 grams per acre of seedbed seeding amount of 400?500 grams, the ratio of seedbed and field 1:8?10, to achieve even sowing evenly sown. In order to achieve a neat seedling, must adhere to? Three wet? The sowing technology, that is, wet seedbed soil, wet seed, wet cover.
4, seedbed management. After the full seedlings, remove the cover, keep the seedbed soil moist, 3?4 true leaves when weeding seedlings, splashing 5% dilute fecal water to raise seedlings. If there is seedling disease, you can use Tolbutrazine 1000-1500 times liquid splash. Seedling aphid control, mu with a net 20 grams of water 20 kg spray. Prevention and control of Lepidoptera damage, mu with 20% chrysanthemum horse emulsion 50 ml to 30 kg of water spraying.
(2) field management
l, apply sufficient base fertilizer. Rice paddy expansion planting squash, mu with 60 kg of ammonium carbonate, 30 kg of phosphate fertilizer mixed with sprinkler and then turned over for base fertilizer, surface fertilizer mu with 30 kg of phosphate fertilizer, mixed with soil fertilizer 30 quintals hole. Ramie soil, cotton soil planting cabbage, mu ammonium carbonate 30 kg, combined with deep plowing soil buried Shi, the growth period focus on splashing. Heavy bottom fertilizer. 3 is now head of fertilizer, in the vegetable seedlings began to head, with a concentration of 50% of the fertilizer applied once to promote the growth of the head; 4th is the attack package of fertilizer, in the head of the wine glass size, with eighty percent of the human and animal feces plus twenty percent of the water, the pursuit of a time, about 3000 kg per acre, in order to promote the head of the rapid expansion of the head of vegetables, to avoid the early extraction of moss, affecting the quality of the head of vegetables.
2, ridge box specifications. Paddy expansion package ditch 2.5 meters sub-compartment is appropriate, must be dug around the ditch, compartment ditch, reduce the water table, conducive to the winter growth of squash, cotton soil to the original ridge compartment specifications transplanted, ramie soil should be good soil rectification.
3, timely transplantation. In 3?5 days before transplanting, the seedbed in addition to weed, the main rip off 5?7% mutant plants, mutant plant performance than the normal seedling high 5?7 cm, especially lush. Leaf age 5?6 leaves, seedling age 30?40 days to start transplanting, paddy expansion requirements in November 5 planting. Dry soil requirements on November 15 planted.
4, plant enough basic seedlings. Paddy transplanting specifications 6X 9 inches, 0.8 to 10,000 root and stem per mu. Requirements in the seedling pulling 10 hours before the seedbed splash wet, to avoid damage to the root system, to improve the survival rate.
5, strengthen the pest control. Leaf shrinkage disease (i.e., virus disease), mainly transmitted by aphids. If in the seedling, transplanting and vegetable head open root and stem, with 2000 times Lego liquid spray 1 time. This will effectively control aphids, greatly reduce the damage of leaf shrinkage disease, and ensure that the head of the vegetable gets high yield.
6, timely harvest. General early and medium maturity fresh vegetables with varieties, in mid-December began to harvest supply market. Specialized processing varieties of squash, generally in the spring around the beginning of the harvest. Harvesting too late, heavy moisture, easy to hollow, tendon more, affecting the processing quality.
7, selecting seeds to keep seeds. Stay seed plants to choose no pests and diseases, with the characteristic features of the variety, the head shape is good, medium size is good, stay seed plants do not transplant. In order to improve the quality of seeds, to be centering treatment, to be separated from the breeding of vegetables, so as not to tamper with the flowers, reduce the quality of seeds.
