A kind of square integrated cultivation method of sericulture tree

Abstract

The invention provides a mulberry tree square integrated cultivation method. The mulberry tree square integrated cultivation method comprises the following steps that a mulberry field is divided into cultivation areas and non-cultivation areas, each non-cultivation area is the interval between every two cultivation areas, each cultivation area is square, and the four corners of each cultivation area are mulberry tree planting points; each cultivation area is ploughed deep, fertilization and watering are conducted on the center of each cultivation area, and every time watering is conducted, the mulberry trees are watered thoroughly. According to the mulberry tree square integrated cultivation method, on the condition that the total number of the mulberry trees is not changed, the planting space of the existing mulberry trees is changed, then, the principle of the combination of sparseness and denseness is applied in a matched mode, and therefore the purposes that arrangement is more reasonable, the ventilation and light transmittance conditions are improved, and the photosynthesis of the mulberry trees is improved are achieved. In addition, by the adoption of partial intensive cultivation and centralized trial of efficient slow release fertilizer, the utilization rate of the fertilizer is improved, therefore, the cultivation technologies such as mulberry filed cultivation, mulberry field fertilization and mulberry field management are highly integrated, finally, the mulberry leaf yield is improved, the mulberry leaf quality is improved, the labor intensity is relieved, and the economical benefits of mulberry tree planting are increased.

Description

technical field

[0001] The invention relates to a method for cultivating silkworm mulberry trees, in particular to a square integrated cultivation method for silkworm mulberry trees. Background technique

[0002] Fengxian County, Jiangsu Province is a plain area formed by scouring and silting after the ancient Yellow River was diverted. The layer is rich in various mineral trace elements needed for plant growth and various organic and inorganic nutrient fertilizers, so the soil is very fertile. In addition, Feng County has a warm climate, four distinct seasons and abundant sunshine, which is very suitable for the growth of crops, especially the growth of sericulture trees.

[0003] Mulberry tree is a deciduous tree with well-developed root system, strong germination ability, fast growth, light-loving, moderate branch density; drought and cold resistance, temperature and humidity resistance, and relatively high alkali resistance. In addition, mulberry leaves are the main fo...
