How to increase yield by planting Virgin Fruit in greenhouse

Virgin fruit, commonly known as small tomato, is a kind of fruit and vegetable that we often eat, but recently, the planting of virgin fruit has developed rapidly, and the benefit of planting in winter will be higher. But the winter temperature is low, although through the greenhouse cultivation, but the yield is still not as good as other seasons, so winter greenhouse planting virgin fruit how to increase the yield? Let's take a look.

1. Promote seedling retardation

The slow seedling stage of the virgin fruit caused by winter is in the cold season, and the greenhouse temperature is mainly suitable, which is beneficial to the growth and development of the virgin fruit. At the same time, attention should be paid to adjusting the light and humidity in the greenhouse, and at the same time, the new high fat film can be sprayed in time. This can effectively prevent the aboveground water from evaporating, the seedling water does not transpirate, shorten the slow seedling period, promote the plant to adapt to the new environment as soon as possible, and make it grow healthily.

2. Fertilizer and water management

In the growing period of virgin fruit, it is necessary to reasonably water and fertilize according to the needs of plant growth, and apply nitrogen, phosphorus and potassium fertilizer in a balanced manner to ensure sufficient nutrients for plant growth. Planting virgin fruit in greenhouse grows very fast, although the plant is tall, but the upright is poor, so when the plant grows to 30-40 cm, it should be pulled by a rod or cable in time to prevent lodging. At the same time, hormone was sprayed to force the top nutrition of the plant to return and turn the trunk nutrition to young fruit development, which could not only improve the fruit expansion speed, but also avoid the phenomenon of leaf hypertrophy and branch and leaf overgrowth, and effectively improve field permeability.

3. Increase the fruit setting rate.

Because the greenhouse environment is closed, the wind is small, and there is basically no insect activity, the fruit setting rate is lower than that of open field cultivation. in order to improve the fruit setting rate of virgin fruit in greenhouse, vegetable fruit Zhuangtieling is generally sprayed before flowering, young fruit stage and fruit expansion period. enhance the quality of pollen fertilization and improve the rate of cyclic fruit setting. It can also promote the growth and development of fruit, prevent the occurrence of cracking and abnormal fruit, further improve the quality of fruit, and result in high yield.

4. prevention and control of diseases and insect pests

The common diseases of virgin fruit are bacterial wilt, blight and so on. Ventilation management should be strengthened in greenhouse cultivation in order to reduce the humidity in the greenhouse and reduce the breeding of bacteria. Regular inspection should be carried out, and when diseases are found, targeted prevention and control measures should be taken to prevent, control and protect them, and timely harvest should be achieved at the same time to ensure high yield and high quality.
