Rice high-stubble wheat zero-tilling drilling method

Abstract

The invention discloses a rice high-stubble wheat zero-tilling drilling method, comprising the following steps: when rice is harvested, leaving high-stubble straws in field, harvesting to obtain ears of rice and short straws, smashing the short straws and directly sowing the short straws in field; performing zero-tilling drilling on high-stubble rice straws; and ditching on field which is sowed with wheat. The method reduces consumption of original power of a harvester, reduces loss of grains when rice is harvested, and increases yield of rice, reduces soil gaps caused by straw turnover, and meanwhile high-stubble parts cover field surfaces and naturally rot, so as to solve problems that soil gaps are too large and wheat is lack of moisture and is sparse caused by original total straw return. The method realizes thermal insulation, moisturizing, water retention, and soil moisture conservation, and increases germination rate of wheat seeds, ensures full stand, seedlings in order, and strong seedlings when seeds are sown, and frozen seedlings and dead seedlings do not occur in winter. The method improves content of organic matters in soil, enriches soil fertility, saves fertilizer and water, so wheat production realizes continuous high efficiency, high yield, high quality, green, and sustainable development.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a no-tillage drill method for rice with high stubble and wheat. Background technique [0002] The existing method of harvesting tillage and sowing is as follows: after harvesting, it is burnt out with a fire, and only a few root stubbles are left in the soil, and the sowing operation is carried out by rotary tillage and no-tillage drill methods. This method of harvesting, plowing and sowing not only pollutes the environment, but also causes soil compaction, soil fertility decline, and soil organic matter content is extremely reduced, which affects the middle and late growth of wheat, and the yield decreases. Therefore, it is difficult to maintain high yield and high efficiency. [0003] In the rice-wheat rotation area, no-till drill is a key technology for high-yielding wheat. Due to the comprehensive implementation of the ban on straw burning, a large amount of...

Problems solved by technology

Due to the comprehensive implementation of the ban on straw burning, a large amount of rice straw cannot be processed, and the utilization rate of straw in my country is not high. At present, only returning to the field is used to improve soil fertility and organic matter content. Returning a large amount of rice straw to the field will easily cause soil voids to increase. Large, lack of soil and water loss is not conducive to wheat seedling emergence, and it is easy to cause dead seedlings in the later stage

The growers have increased their investment. If they leave the field and do not deal with it, it will still cause environmental pollution.

There are two main farming methods in the current rice-wheat rotation area: one is to remove all rice stalks from the farmland after rice harvesting, and carry out operations by rotary tillage or no-tillage drilling. This method requires a lot of manpower and material resources, and still causes soil compaction. Moreover, burning the removed straw in other places still pollutes the ecological environment; the other is to leave low stubble when rice is harvested, return the full amount to the field, and use a high-powered tractor to carry out rotary tillage for stubble removal, and then sow and suppress. If it is large, the soil gap will be enlarged, the soil will be ventilated, resulting in uneven seedlings, poor water retention, and easy to be frozen in winter, which will reduce the overall quality of wheat seedlings, and the lack of basic seedlings will affect the whole seedlings sown and directly affect the yield of wheat.
