Women sow in late autumn or early spring.
Cultivation points: choose good land, orchard hill and flat land. In the selected plot, 4000 kg of ring fertilizer and 30 kg of compound fertilizer are evenly applied to the ground, and the ridge is leveled after ploughing, and the width of the ridge is 1 m, which is beneficial to management and operation. Sporadic growth in fields, grids, old house frames and fences. Strong adaptability, fast growth, easy cultivation and management, once planted, it can benefit for decades. In Liaoning province, brocade germinated in early May, blossomed in mid-June and matured in late September. Generally, the plant height is about 50 cm, and a large number of tillers germinate in mid-July, with 5-7 plants strung together and weighing 250 grams.
Seed propagation
When the seeds are propagated, the seeds are harvested in June+10/October, 5438, washed and dried in the shade. Before June 5438+065438+1October 10, soak the seeds in clean water indoors for 24 hours, then take out the clean water and mix it evenly with fine sand twice as much as the seeds. The humidity standard is that the seeds are held by hand and opened at the touch. Then, put it in a breathable bag, dig a hole 30 cm deep in an outdoor place with high terrain and dry sandy loam, put the seed bag into the hole, and cover it with 10 cm thick soil. After freezing, cover the ground with 10 cm thick plastic film to delay the rise of ground temperature in early spring, so as not to cause seeds to germinate underground. Remove the plastic film five days before sowing. When sowing, take out the seeds and sand and spread them at the same time. Draw a ditch with a depth of 1- 1.5 cm according to the row spacing of 25-30 cm, and sow seeds with fine soil or sand of 0.8 cm? 1 cm and then water, and the temperature is suitable for 7- 15 days. In about 28 days, when the seedlings grow to 3-4 leaves, they can be planted. Double rows are used, the row spacing is 60-70 cm, the spacing between plants is 20-25 cm, and two plants are fixed in each hole.
In addition, the tillering ability of plants is very strong. From the second year of planting, each plant can grow 6-8 new buds from the ground, which leads to the decline of soil fertility and poor ventilation. In production, redundant sprouts are transplanted in rainy season, with high survival rate and low cost.
Rhizome propagation
Sow in late autumn or early spring. The yield of autumn sowing is higher than that of spring sowing, with 40 kilograms of seed roots per mu. Before sowing, cut the seed root into small pieces of about 3 inches, leaving 2-3 bud holes in each section. Then, the seed roots are mixed with plant ash, a ditch with a row spacing of 30 cm is opened in the whole seedbed, and the mixed seed roots are laid flat in the ditch, covered with soil, slightly vibrated and watered, and the appropriate temperature is about 20 cm. No thinning is needed in the first year, and the seedling height in the second year is 10 cm, and the seedlings are fixed according to the spacing of 15 cm.
For high yield and premature delivery, the seedling height of Golden Lantern is 10 cm. Combined with intercropping weeding, 20 kg of urea and 20 kg of chemical fertilizer should be applied in May and June, and drainage should be paid attention to in rainy season. Spraying dwarfing hormone twice during the growth period to prevent overgrowth. Spraying manganese twice before fruit harvesting to prevent Veronica blotch can improve early maturity and yield.
Sowing method
Sowing, summer sowing, autumn sowing, autumn sowing. Spring sowing can be divided into spring sowing (1): the planting plot is turned 30cm deep and leveled, and the furrow depth is 1. 5 cm, the planting density is 30 seeds per linear meter, and then the seeds are stepped into the soil with a covering thickness of about 1 cm. (2) Summer sowing: Use the vacant plot to cut off weeds in the field before July 25th, mix the seeds with wet sand, lift them evenly on the surface by hand (500g seeds are used for 667m2), and then hold them tightly with an iron rake to a depth of 2-3cm until the rainy season in August. (3) Autumn sowing: The method is the same as spring sowing, and the sowing period is 10 month, which is completed before freezing, but the seeds sown in autumn need not be frozen.
The field management of lanterns is extensive. Primary school students should shovel weeds twice at seedling stage and before flowering, and generally do not need management from flowering to harvest. Starting from the second year, it is necessary to remove redundant new buds in time. There are about 50,000 seedlings per 667 square meters. The output of brocade lanterns planted in that year was not high, and it continued to increase from the second year. There is no disease in the growth period and it can be classified as an immune variety.
