Generally, the yield per mu of strawberries in greenhouses is 2,000 to 3,000 kilograms. The yield per mu of strawberries is affected by factors such as region, variety, climate, etc. For example, the yield per mu of strawberries with high quality can reach 4,000 to 5,000 kilograms, while the yield per mu of strawberries with slightly lower quality The average strawberry yield per mu is 1,500 to 2,500 kilograms.

Strawberry cultivation technology

Selection of land

The root system of strawberries is relatively shallow. When planting, choose neutral soil with a pH value between 6 and 7. The requirements It is rich in a variety of organic matter and has good water and fertilizer retention effects. In particular, it is necessary to avoid saline-alkali soil, swamps and soil that is too heavy, because strawberries are afraid of waterlogging, and the soil's drainage capacity should be good.

Strawberry fields should be fertile land with slightly higher terrain, flat ground, convenient drainage and irrigation, good lighting, rich organic matter, strong water retention, good ventilation, and a weakly acidic or neutral pH value. The best crops for the previous crop are vegetables, beans, melons, wheat, etc.

Before planting strawberries, weeds should be thoroughly removed and decomposed farmyard manure should be applied. Generally, 5,000 kilograms of organic fertilizer, 50 kilograms of superphosphate, and 50 kilograms of potassium chloride are used as base fertilizers per acre. After spreading evenly, Plow 30 to 40 cm to promote soil maturation. After the land is leveled, make a border of 100 cm. The width of the border is 80 cm, the width of the furrow is 20 cm, the height of the border is 15 cm, and the length of the border is 20 meters. ?

Colonization

The quality of planting has a great impact on the growth and future management of strawberries, so careful efforts must be made in planting.

When planting strawberries, attention should be paid to directional transplantation, with the backs of the seedlings facing the ditch side so that the inflorescences grow in the same direction. The number of plantings is one plant per hole, and no holes should be buried above the planting depth. , it is better not to expose the roots.

Reasonable dense planting: The planting density of strawberry is closely related to the planting level. Fields with weak seedlings, late planting, and lack of fertilizer should be dense. The planting density is about 8,000 plants per acre. On the contrary, strong seedlings, Early planting, sufficient fertilizer, and mulching technology should be used to plant sparsely, with 6,000 plants per acre and a plant-row spacing of 50 cm × 20 cm. ?

Watering

Water thoroughly after planting. Generally, water once in the morning and once in the evening within a week after planting. In the future, the soil should always be kept moist to facilitate survival. ?

Fertilization

Strawberries require more fertilizer from planting to flowering and bearing fruit. In addition to applying sufficient base fertilizer, fertilizer must be added in a timely manner. This can be done during the fruit expansion period and the beginning of harvest. Apply 10 kg of strawberry-specific fertilizer or diammonium phosphate per mu. The effect of furrow application in the form of 200 times liquid fertilizer combined with watering is better. Only spraying 0.1 to 0.2% potassium dihydrogen phosphate 2 to 3 times on well-growing fields will also have a certain yield increase effect. In principle, no spraying is required during the flowering period. The principle of fertilization in fruit-picking fields is appropriate N and P and K. A reasonable ratio must be maintained to obtain higher yields and maximum benefits. ?

Mulching

Multifilm mulching has significant early-maturing and yield-increasing effects. It can also improve fruit quality and increase commercial fruit rate. Film covering usually starts in mid-to-late March.
