Rapid decomposition method for returning summer maize straws

Abstract

The invention discloses a rapid decomposition method for returning summer maize straws, which is used for solving the problem of decomposition of the maize straws. The method comprises the following steps of: crushing the maize straws in the fields, and totally and directly returning the crushed maize straws; after the crushed maize straws are returned, broadcasting materials, such as a decomposition agent, accessory ingredients and the like, in a way that 2 to 2.5 kilograms of decomposition agent, 3 to 5 kilograms of accessory ingredients, 0.5 to 1 kilogram of water-retaining agent and 6 to 8 kilograms of urea are broadcast into each acre of land; and timely performing ploughing or rotary tillage and sowing winter wheat after a week. The method has the main advantages that: 1, the summermaize straws are mechanically crushed in situ and then totally and directly returned and utilized, so the problems of difficulties in the collection, transportation and storage of the maize straws are solved; 2, the maize straws are rapidly decomposed, so the straw decomposition rate is increased, soil nutrients are returned, soil conditions are improved, simultaneously seedlings of the followingwinter wheat come out uniformly and the rate of emergence is greatly increased; and 3, farming in the fields is easy to operate and execute, and the method is delightedly accepted by farmers and is convenient to execute.

Description

Technical field [0001] The invention relates to a technology of returning corn stalks to the field, in particular to a rapid decomposing method of summer corn stalks, and belongs to the technical field of fertilizers. Background technique [0002] Corn is one of the main crops, and hundreds of millions of tons of corn stalks are harvested every year, which is a precious resource that has not yet been fully recycled. Corn stalks have a rough texture and poor palatability, and their intake rate as animal feed is very low; if they are used for edible fungi cultivation, there is a problem of low yield; if the straw is burned, it will cause air pollution and destroy the organic matter and Contained nutrition. Returning corn stalks to the field is an effective method to supplement and balance soil nutrients and improve soil. It is one of the basic measures for high-yield field construction. It is of great significance for improving resource utilization, improving arable land soil ...

Problems solved by technology

This method solves the difficulty of transportation and storage of corn stalks to a certain extent, but there are still problems of labor, time-consuming, laborious, and land occupation

Another method is to use a combine harvester to harvest corn while mechanically crushing corn stalks and returning them directly to the field. The adva
