The latest key points of post-harvest management of loquat

The mature market period of loquat is from May to June every year, and some precocious loquat can be listed in March-April. The management must keep up with the management after loquat harvest in order to maintain the high yield in the second year and avoid the phenomenon of big and small years. So how to manage loquat after picking? Let's take a look at the detailed introduction.

1. Summer pruning

Summer pruning after picking is also the most important pruning of loquat, and it should be early rather than late, the most important branch of loquat plant in summer shoot. For different fruiting trees, early flowering and early flower bud differentiation, summer pruning is generally thinning the crown, such as dense branches, weak branches, overlapping branches, cross branches, long branches and so on. Increase the permeability of the plant, lay the foundation for flower bud differentiation, and truncate the fruiting branch to prevent the shoot from moving out and the base bald.

2. Overall cleaning of the garden

After pruning, the weeds in the orchard should be cleared so as not to compete with the plants for water and fertilizer, affecting the growth of the plants, burning the weeds removed and pruning fallen branches and leaves, and the rest of the plant ash is just the potash needed for plant growth. Weeds and branches and leaves can also be buried as green manure, and can also provide nutrients for plants.

3. Trenching and drainage

Summer is a period of high temperature and rainy weather, especially in the south, it is the Meiyu weather, which is very prone to torrential rain, so it is necessary to do a good job in ditching and drainage measures to avoid stagnant water and rotten roots. The period from June to July is the period of flower bud differentiation of loquat, when keeping the soil under proper drought, this method can promote the growth of aboveground branches and increase the concentration of cell sap at the growth node, which can promote the flower bud differentiation. It can be used to cover grass near the tree plate to improve the drought resistance of the plant and reduce soil fertilization.

4. prevention and control of diseases and insect pests

High temperature and humidity in summer can easily induce diseases, especially leaf spot, anthracnose, rot and yellow caterpillar, which will seriously affect plant growth and even plant death. In order to take preventive measures, Bordeaux solution and carbendazim can be sprayed before shoot emergence, and corresponding agents can be sprayed after the occurrence of diseases. For pests, artificial killing and chemical control can be used to burn their heavy cocoons, and the larvae can be sprayed with permethrin or dichlorvos.
