Embodiment 1

[0045] From 2007 to 2008, this method was adopted in Jinhua Village, Lianshan Town, Guanghan City. The full amount of rice and wheat straw was returned to the field. After rotary tillage and land preparation, the rice was transplanted mechanized. Yuan / mu, output 579kg / mu, output value 1274 yuan / mu, net income 774 yuan / mu. Wheat is sown with a 2BMFDC-6 seeder, the sowing efficiency is 20 mu / day, the labor input during the whole growth period of wheat is 180 yuan / mu, the output is 480kg / mu, the output value is 960 yuan / mu, and the net income is 560 yuan / mu. In the comparative field using the traditional method, the wheat straw was burned after the wheat was harvested, and then the rotary tiller prepared the land, and the rice was artificially planted. The planting efficiency was 0.3 mu / day, the labor input during the whole growth period of the rice was 400 yuan / mu, and the output was 610kg / mu. 1342 yuan / mu, net income 692 yuan / mu. Wheat is sown by no-tillage sowing, the sowing ...

Embodiment 2

[0047] From 2008 to 2009, this method was adopted in Jinhua Village, Lianshan Town, Guanghan City. The rice and wheat straws were returned to the field in full.

[0048]The long-term labor input is 250 yuan / mu, the output is 574kg / mu, the output value is 1263 yuan / mu, and the net income is 763 yuan / mu. Wheat is sown with 2BMFDC-6 seeder, the sowing efficiency is 20 mu / day, the labor input in the whole growth period of wheat is 180 yuan / mu, the output is 465kg / mu, the output value is 930 yuan / mu, and the net income is 530 yuan / mu. In the comparison field using the traditional method, the wheat straw was burned after the wheat was harvested, and then the soil was prepared by a rotary tiller, and the rice was artificially planted. The planting efficiency was 0.3 mu / day, the labor input during the whole growth period of the rice was 400 yuan / mu, and the output was 602kg / mu. 1324 yuan / mu, net income 674 yuan / mu. Wheat is sown by no-tillage sowing, the sowing efficiency is 0.5 mu / d...

Abstract

The invention belongs to the technical field of tillage cultivation, and discloses a method for straw full-amount returning and rice-wheat planted seedling in a rice-wheat double cropping area. Under the condition of rice-wheat double-season straw full-amount returning, planted seedlings of next-stubble crops are not influenced, and due to the fact that mechanical operation is adopted in a key production link, labor intensity and production inputs are greatly reduced. In addition, straw returning is further favorable for soil fertilizing and environment protection.

Description

technical field [0001] The invention relates to the technical field of farming and cultivation, in particular to a method for returning full amount of straw to the field in a double-cropping area of ​​rice and wheat and sowing and planting rice and wheat for erecting seedlings. Background technique [0002] The area of ​​rice and wheat double-cropping area in my country is about 5 million hm 2 , mainly distributed in the Yangtze River Basin, is an important grain producing area in my country. The rice and wheat double-cropping area has high soil fertility, good light and heat resources, abundant rainfall, high grain output (more than 1 ton / mu), and a very large by-product-straw output. Before the 1990s, crop straw was mostly used for fuel or animal feed. With the development of the economy, the improvement of the rural fuel structure and the no longer breeding of cattle, a large amount of straw has become a burden on production. [0003] There is no doubt that straw retur...
