Taking the common strawberry planted in greenhouses as an example, its mu yield is generally 2000-3000 pounds. The acreage of greenhouse strawberries will be affected by factors such as region, variety and climate, for example, the acreage of strawberries with good varieties can be as high as 4,000-5,000 pounds, while the acreage of strawberries with poorer varieties may only be about 1,500-2,500 pounds. Strawberries are usually grown in a 3-year cycle, with the least amount of strawberries harvested in the first year and the most in the second year.
A, strawberry mu yield is generally how many pounds
1, in order to greenhouse planting of ordinary strawberries, for example, its mu yield is generally 2000-3000 pounds. The acreage of greenhouse strawberries will be affected by varieties, regions, and climate factors, for example, some varieties of strawberries can be as high as 4,000-5,000 pounds of acreage, while some varieties of poor acreage may only be 1500-2500 pounds or so.
2, strawberry planting has a 3-year cycle, usually the first year to harvest the least amount of strawberries, the second year to harvest the most, to the third year or three years later, strawberry production will be significantly reduced, the need to replace the plant, reasonable arrangements for the cultivation of new plants, to ensure that every year there are some strawberries are the second year of birth, to ensure that you can get the maximum economic benefits.
Second, the strawberry planting technology
1, the selection of land rectification
Strawberry garden should be selected a little higher terrain, light, irrigation and drainage convenience, the ground is flat, fertile and loose soil, the previous crop for beans or onion and garlic vegetables as appropriate, the garden should be the first to remove the weeds, the extermination of underground pests, can be used in the 50% phoxim emulsion 1000 times spray (wet) 1000 times liquid spray (wet soil layer 5-6 cm), control mole crickets, grubs, tigers. 1 week later, mu basal application of high-quality rotted farm manure 5000 grams, 50 grams of potassium chloride, 100 grams of calcium superphosphate. Combined with fine land preparation, deep turning of the garden, made into a 50 cm wide, 20 cm high border, border ditch width of 30 cm.
2, transplanting technology
In order to strive for the end of January to the beginning of February strawberries can be marketed, breeding nursery strawberry seedlings transplanted greenhouse beds should be selected in early September, with the rise of the seedlings, with the transplantation, each bed row spacing 27 cm, planted in 2 rows per bed, hole spacing of 20 cm, mu planted 12,000 plants. When planting the inflorescence of the same line of plants in the same direction, so that the heart of the seedlings exposed border, the root system spread buried in the loose soil layer, timely watering planting water, and make the exposed roots buried in the soil layer.
3, planting management
(1) plowing and fertilization: plowing and loosening the soil, is conducive to the decomposition of organic matter, January to December should be shallow plowing 3 times, the early flowering and fruiting of the early stage of each of the fertilizer 1 time, mu of phosphorus fertilizer 20 kg, 10 kg of urea, 10 kg of potassium chloride, or ternary compound fertilizer 35 kg.
(2) the management of the pre-flower bud differentiation: early September transplanted strawberry seedlings, in addition to timely supplemental water, should be covered with shade net shade. To remove the old leaves, dead leaves and axillary buds and stolons in a timely manner, keep 5-6 leaves, net 1.2 meters from the ground, easy to operate.
(3) irrigation and drainage methods: flowering and berry growth in the early stages, respectively, to irrigate 1 time, it is desirable to use the furrow irrigation, so that the water irrigation to the ditch height 2/3 is good, so that the water gradually seeped into the bed soil, so that the remaining water in the ditch discharge.
(4) cover plastic film: October to early November, is the end of the strawberry inflorescence differentiation period, you can remove the shade net, in the river quasi-region, ? The big snow? Before covering the greenhouse film,? The winter is coming. After covering the film, so that the temperature in the shed to maintain 28-30 ℃.
(5) ventilation operation: strawberry seedlings growing soil humidity should be 70% -80% appropriate, air humidity to 60% -70% good, when the shed temperature exceeds 30 ℃, should be ventilated, when the shed humidity exceeds 70%, should also be ventilated, the flowering period of the shed to put bees, can be in the large, medium shed at both ends of the other to do the nylon wire mesh, to facilitate the smooth ventilation, November to December should be 10 am to 3 pm. In November and December, it should be opened at 10 a.m. to 3 p.m. to ventilate the plastic film at the ends of the shed and the middle shed.
(6) Harvest: strawberry seedlings blossom, fruit to berry coloring, softening, release the characteristic flavor, the time is about 30 days, strawberry berry ripening, should be harvested in batches on the market.
