The latest course of management techniques and methods of big cherry in greenhouse

Cherry is now a popular fruit in our country. When many people plant cherries, they mainly plant them in the open air. The use of greenhouse planting is actually more powerful for the yield and quality of cherries. Can effectively reduce a variety of bad phenomena, so we in the greenhouse cherry planting how to manage it? Today, the editor has brought you the management technology of cherries in the greenhouse. Let's take a look at it.

1. Drip irrigation under plastic film

When many people plant cherries in the greenhouse, most of their watering methods are based on flood irrigation. In fact, this can easily lead to high humidity in the greenhouse, which can easily lead to poor pollination and fertilization of cherries during flowering. It is also easy to cause vigorous growth of branches and leaves after flowering, resulting in insufficient nutrition supply of flower buds and young fruits, which reduces the fruit setting rate, and is also easy to produce diseases. Therefore, we should give priority to drip irrigation under plastic film and provide regular and quantitative supply according to the demand of cherry trees. It can not only reduce water waste and avoid soil consolidation, but also reduce the humidity in the greenhouse and increase the fruit setting rate.

2. Plastic film mulching

When planting big cherries in the greenhouse, the mulching film is mostly black plastic film. Although the black base film has strong heat preservation, it can prevent the growth of weeds. However, its light transmittance is very poor, which will affect the improvement of ground temperature. This is also a major factor leading to the low temperature of the greenhouse and the irregular flowering of cherries. Therefore, when we cover the plastic film, it is best to give priority to the white plastic film. Data have shown that it takes about 11 days for black mulch to raise the soil temperature of about 20 cm to 15 degrees, while it takes only 8 days for white mulch. For weeds, we can pull them out manually.

3. Laying reflective film

When planting, big cherries generally have the phenomenon of poor coloring. This phenomenon is caused by excessive nitrogen fertilizer, insufficient potassium fertilizer and trace elements, temperature discomfort and other reasons. Greenhouse film hinders the transmission of sunlight is also a major factor. Because in order to reduce the damage caused by this situation, we have to lay a reflective film under the crown and in the middle of the trunk of the tree. Improve the lighting environment of the inner chamber and the lower part of the cherry tree. Maximize the use of sunlight, enhance the photosynthesis of trees, and promote the fruit to be colored as soon as possible.

4. Foliar fertilizer application

When spraying foliar fertilizer to big cherry, we should pay attention to control the application of inorganic foliar fertilizer. If the inorganic foliar fertilizer is applied too much, it will affect the root growth. Therefore, when we plant, we should choose some organic foliar fertilizer with fast absorption rate and adequate nutrition according to the growth law and actual situation of big cherry. Such as amino acids and humic acid, which can not only supplement nutrition, but also will not hinder the absorption of inorganic nutrients by big cherries, and improve the flowering and fruiting rate of big cherry trees.

The above is a brief introduction to the management technology of big cherry in greenhouse. That's all for today's introduction. This article is for reference only. I hope it can help you all.
