The roots of autumn cherry grow rapidly, and the number of hairy roots is large. The cut roots produced by fertilization in autumn are easy to heal, and it is beneficial to multiple rooting. Fertilizer can be used to fertilize in the year, increase the nutrient reserve before winter, increase the cold resistance ability of the tree, and increase the fruit. Quality and output. Therefore, we should pay attention to the fertilization in autumn and lay a good foundation for the high yield of cherry in the coming year. The big cherry orchard is used earlier in autumn, and it usually starts from August to September.
Fertilization plan:
1. Strip groove application applies to base fertilizer. Trenches are applied to the outer edges of the crowns corresponding to the tree body. Each year, one direction is used alternately. When basal fertilisers are used in autumn, the ditch is larger, usually about 30 to 40 cm.
2. Annular furrows excavate an annular groove at the periphery of the crown. The depth, breadth and width of the furrow are the same. This method is mostly suitable for young trees with a small root distribution.
3. Spread the fertilizer evenly under the tree and then plunge into the soil to a depth of about 20 cm. However, due to shallow application, it often leads to the floating of the root system and reduces the stress resistance of the root system. It should be conducted every other year with the radiation groove method.
4. Fertilization must be used in conjunction with photosynthetic nutrient film fertilizer, which can help plants absorb a lot of light, light, light, compatible with conventional fertilizers, nutrients supply plant growth and development to the limit. Apply once a year to benefit.
5. Autumn basal fertilizer should be based on the tree's vigor, tree size, the amount of results, there are some results of soil testing formulations to apply some fruit tree compound fertilizer, and timely addition of trace elements.
Plasticizer is widely used in industrial production of polymer materials, also known as plasticizer. Any substance added to a polymer material that increases the plasticity of the polymer is called a plasticizer. Plasticizer can improve the performance of polymer materials, reduce production costs and increase production benefits. [1] is a kind of important additives, chemical products as additives commonly used in plastics, concrete, mortar, the material such as cement, gypsum, cosmetic and detergent, especially in PVC plastic products, in order to increase the plasticity of the plastic and improve the strength of the plastic, you need to add phthalic acid ester, sometimes its content can be up to 50% of the products. Weakened the effect of plasticizer mainly resin molecular valence bond between time, increase the mobility of the resin molecular bonds, reducing resin molecular crystalline, increase the plasticity resin molecules, enhanced the flexibility, easy to machining, can legally used for industrial purposes, widely exists in food packaging, cosmetics, medical equipment, water and environment. Such as plastic wrap, food packaging, toys and so on.
