Introduction of planting time and Technical points of Strawberry in greenhouse

Strawberry has high nutritional value, contains a variety of nutrients and has health care effect. now it is planted and developed in greenhouse, because strawberry cultivation in greenhouse is easy, management is convenient, production cost is low, yield is high, and income is good. it is suitable for the adjustment of farmland structure and the development of benefit agriculture. Let's take a look at the planting time and technical points of strawberries in the greenhouse.

Planting time of strawberries in greenhouse

The time for planting strawberries is in the first and middle of September, and it is also possible to plant in late September in some areas, but the seedlings planted per mu should not be too dense, for if they are too dense, it is easy to cause strawberry seedlings to grow or tall seedlings and poor ventilation and ventilation, which is not conducive to the development of pest control. Generally about 6000 seedlings per mu can, strawberries belong to shallow root crops, so that "deep do not bury themselves, shallow do not show roots".

2. Planting techniques of strawberries in greenhouse

1. Land preparation and variety selection

The strawberry orchard should choose sandy or loam soil with flat ground, slightly higher terrain, deep, loose, fertile and well-ventilated soil. The garden can be sprayed with 1000 times of phoxim EC to control grubs, mole crickets, tigers and other pests. Varieties such as Jinxing and carbonfeng should be selected with strong growth potential, high fruit setting rate, shade tolerance, cold tolerance, powdery mildew resistance and short dormancy period.

2. Planting the buckle shed in time

In order to get on the market as soon as possible, strawberries should be transplanted into the greenhouse in early September. Transplant with the seedlings. 2 rows per row, 25 cm between rows and 20 cm between holes, about 12000 plants per mu. Plant water in time and bury the exposed roots in the soil. The time of withholding shed is usually around the middle of November.

3. Temperature and humidity management

The optimum temperature for strawberry fruit development is 18-25 ℃. In order to reach this temperature in winter and early spring, plastic film can be covered in a greenhouse. The indoor temperature in the greenhouse is kept at 28-30 ℃ in the daytime and above 5 ℃ at night. When there is a high temperature of more than 30 ℃, it is necessary to ventilate and cool down in time. When the humidity in the shed exceeds 70%, it should be ventilated in time.

4. Fertilizer and water management

The fruiting period of strawberries in greenhouse is long. in order to prevent early senescence, high-quality mature farm manure should be re-applied, topdressing in time and foliar fertilizer should be sprayed frequently. Irrigate immediately after planting. Irrigate once at the initial stage of flowering and berry growth. If there is a drought, it should be irrigated once every 5-7 days. When it is rainy in autumn, it should be drained in time. Drainage ditches should be made around the strawberry orchard so that the furrow water in the shed can be drained.

5. Ploughing and loosening the soil and picking leaves and thinning fruits

Ploughing and loosening the soil is beneficial to the decomposition of organic matter. Remove diseased old leaves and weak fruits to reduce nutrition consumption, which is conducive to strawberry growth and berry development.

6. Integrated control of diseases and insect pests

Agricultural control is the main control of strawberry diseases and insect pests in greenhouse, supplemented by chemical control. The occurrence of diseases and insect pests can be prevented by selecting disease-resistant varieties, cultivating virus-free strong seedlings, high ridge planting, plastic film mulching, reasonable crop rotation, cleaning soil, avoiding drought, high humidity and so on. If diseases are found, attention should be paid to the unsuitable use of drugs before and after flowering, so as not to affect pollination and increase the number of abnormal fruits. High efficiency, low toxicity and low residue pesticides should be selected and the pesticide dosage and safety interval should be strictly controlled. If Botrytis cinerea occurs, 25% carbendazim wettable powder can be sprayed with 300 times liquid.

7. Timely harvest

Strawberries are usually picked at 8-10:00 or 4-6 p.m. Generally do not pick fruit and sun-heated fruit, so as to avoid decay and deterioration. When harvesting, handle it gently and do not damage the calyx.
