Synergistic cultivation method for sweet cherry by reducing application of chemical fertilizer and pesticide

Abstract

The invention discloses a sweet cherry synergistic cultivation method with reduced application of chemical fertilizer and pesticide. The method comprises the steps of fertilizer application and pesticide application. Fertilization comprises soil fertilization and foliage topdressing, the soil fertilization is carried out for four times every year, the foliage topdressing is that nitrogenous fertilizer and / or phosphatic fertilizer and a borax solution are / is sprayed one week before flowering, and a solution containing calcium ions and cane sugar is sprayed to leaf surfaces and fruits after the fruits turn yellow; pesticide application is performed after leaves fall, before germination, before flowering, after flowering and from late June to early July, and a solar frequency vibration lamp, a color plate and a trap are placed at the same time. By adopting the synergistic cultivation method, the utilization rate of the fertilizer can be increased, the use amount of the fertilizer can be reduced, the use amount of pesticide can be reduced, the product safety can be improved, the planting cost is reduced, meanwhile, the soil nutrition environment can be improved, space-time coordination of sweet cherry plant nutrition is achieved, quality and efficiency are improved, and production and income are increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a synergistic and synergistic cultivation method for sweet cherry by reducing the application of chemical fertilizers and pesticides. Background technique [0002] Sweet cherries are the leading industry for farmers to get rid of poverty and become well-off and rural revitalization. However, in the process of industrial development, there are heavy chemical fertilizers and light organic fertilizers, heavy nitrogen and light phosphorus and potassium, heavy macroelements and light trace elements, and excessive use of pesticides causes soil compaction. , Acidification, aggravation of salinization, damage to the soil environment system, and product safety cannot be guaranteed. It is very necessary to carry out synergistic cultivation of chemical fertilizers and pesticides. However, current research is mostly focused on field crops and bulk fruits. Contents of...

[0002] Sweet cherries are the leading industry for farmers to get rid of poverty and become well-off and rural revitalization. However, in the process of industrial development, there are heavy chemical fertilizers and light organic fertilizers, heavy nitrogen and light phosphorus and potassium, heavy macroelements and light trace elements, and excessive use of pesticides causes soil compaction. , acidification, aggravation of salinization, damage to the soil environment system, and product safety cannot be guaranteed. It is very necessary to carry out synergistic cultivation with reduced application of chemical fertilizers and pesticides. At present, relevant research is mostly concentrated on field crops and bulk fruits.
