The Latest Management Techniques and Methods Tutorial for Large Cherries in Greenhouses
Cherries are now a relatively popular fruit in our country. Many people grow cherries mainly through open-field cultivation. However, using greenhouse cultivation is actually more effective for cherry yield and quality. It can effectively reduce various adverse phenomena, so how should we manage large cherries when growing them in greenhouses? Today, the editor brings you greenhouse large cherry management techniques, let's take a look below!
1. Drip irrigation under film
When many people grow greenhouse cherries, their watering methods are mostly based on flood irrigation. In fact, this very easily leads to excessively high humidity inside the greenhouse, and easily causes poor pollination and fertilization of cherries during the flowering period. It also easily causes vigorous growth of branches and leaves after flowering, leading to insufficient nutrient supply to flower buds and young fruit, which lowers the fruit-setting rate, and at the same time it very easily produces diseases. Therefore, our watering should be mainly drip irrigation under film, with timed and quantitative supply according to the needs of the cherry trees. It can not only reduce water waste and avoid soil compaction, but also lower the humidity inside the greenhouse and increase the fruit-setting rate.
2. Plastic film mulching
When growing large cherries in greenhouses, the plastic film used for mulching is mostly black plastic film. Although black film has strong heat preservation and can prevent weed growth, its light transmittance is very poor, which affects the rise of ground temperature. This is also a main factor causing low ground temperature in the greenhouse and uneven flowering of cherries. Therefore, when we cover with plastic film, it is best to mainly use white plastic film. Data has shown that to raise the temperature of a soil layer of about 20 cm to 15 degrees, black plastic film takes about 11 days, while white film takes only 8 days. As for weeds, we can pull them out by hand.
3. Laying reflective film
During cultivation, large cherries generally show poor coloring. Besides causes such as excessive nitrogen fertilizer, insufficient potassium fertilizer and trace elements, and unsuitable temperature, the greenhouse film blocking sunlight transmission is also a main factor. Because of this, in order to reduce losses caused by this situation, we should lay reflective film well under the tree canopy and at positions such as the trunk and central leader of the tree body. This improves the light environment in the inner part and lower part of the cherry tree. It maximizes the use of sunlight, enhances the photosynthesis of the tree body, and promotes early coloring of the fruit.
4. Application of foliar fertilizer
When we spray foliar fertilizer on large cherries, we should pay attention to controlling the application of inorganic foliar fertilizer. If too much inorganic foliar fertilizer is applied, it will affect root growth. Therefore, when growing them, we should, according to the growth pattern and actual conditions of large cherries, during the critical period of fertilizer demand, select in a targeted way some organic foliar fertilizers with fast absorption rates and sufficient nutrition. For example, amino acids and humic acids, etc. This can not only supplement nutrition, but also will not hinder the absorption of inorganic nutrients by large cherries, and improves the flowering and fruiting rate of large cherry trees.
The above is a brief introduction to greenhouse large cherry management techniques. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
