Straw mulching weed suppression cultivation method for orchard

Abstract

The invention discloses a straw mulching weed suppression cultivation method for an orchard, and relates to a weed suppression cultivation method applied to the orchard. Straw is high in degradation speed, does not fight for water and fertilizer with plants in the degradation process and cannot injure plant root systems in the degradation process. Weed suppression composting processing is performed on the land among rows with the straw, and the method comprises the following steps that 1, the land is leveled; 2, the straw is laid; 3, mixtures of a straw decomposition agent and urea are sprinkled on the straw. According to the straw mulching weed suppression cultivation method for the orchard, the straw corruption and degradation speed is accelerated, corruption and degradation are performed on the surface of soil, and the urea is added, so that the straw is prevented from fighting for the water the fertilizer with the plant root systems; gas generated through corruption and degradation is quickly exhausted into air, and therefore harm to the plant root systems cannot be generated; through straw mulching, the growth of field weeds are inhibited, warm keeping and moisturizing are achieved, and therefore overwintering and drought resisting of fruit trees are facilitated; the straw is turned into the soil through one-year decomposition, the soil is improved, the organic matter content is increased, the soil fertility is improved, potassium obtained through decomposition is beneficial for fruiting of the fruit trees, and pollution of straw burning to the air is reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a weed-suppressing cultivation method applied in orchards. Background technique [0002] The orchard needs about 10 manual and chemical weedings every year, which is laborious and time-consuming. The annual output of straw biomass resources in my country is about 700 million tons. Straw resources have not been well developed and utilized for a long time, and crop straws are ineffectively burned or discarded in field ditches from time to time, which not only wastes resources, but also destroys the ecological environment. In the prior art, straws are directly placed between the rows of the orchard to inhibit the growth of weeds, but often the degradation of straws is too slow, and some straws are still very tough in the second year, which affects field operations. Moreover, the straws near the soil surface Straw, in the process of degradation, competes with plants for water...

Problems solved by technology

The disadvantage is that the natural fermentation speed is slow, and the fertilizer after heaping needs to be manually applied to the field, which is dirty and heavy, and the labor intensity is high, and farmers are unwilling to use it.

[0004] An invention patent published by the State Intellectual Property Office on December 10, 2014 (patent name: a cultivation method for furrow and ridge cultivation, application number: 201410382039.4) discloses a method of natural fermentation and degradation of straw buried in the soil alternately. It degrades slowly, and often there will be straw in the next year. During the fermentation process, it competes with plants for water and fertilizer, and the gas produced by fermentation will damage plant roots and affect the growth of crops.
