Problems solved by technology
[0003] In recent years, with the excessive use of chemical fertilizers in the process of rice planting, the soil has become compacted and it is difficult to loosen. It is easy to make the root system of the planted rice lack oxygen, which is not conducive to the growth of rice.
And with the continuous promotion of returning full amount of straw to the field, the amount of straw returning to the field is large, and it is too late to rot. In addition, the early stage of straw rotting consumes a lot of oxygen, which makes the root system in a hypoxic reducing state, which further has a very adverse impact on the growth of rice seedlings.

Embodiment 1
[0020] From June to November 2015, in Yucai Village, Shuxin Town, Chongming County, a comparison experiment between micro-nano bubble water irrigation and conventional irrigation was carried out when the straw was returned to the field. : Shenyou 17; planting method: machine transplanting; the test fertilizers were 45% BB fertilizer (N:P:K=15:15:15), 46% BB fertilizer (N:P:K=26:8:12 ), urea (N=46%), diammonium phosphate (N:P:K=15:42:0). The specific planting steps are as follows:
[0021] (1) Finely prepare the soil, soak the field with water, and apply base fertilizer deeply;
[0022] (2) machine-transplanted rice seedlings, the plant spacing is 14cm, and the row spacing is 30cm;
[0023] (3) About 3 days after transplanting the seedlings, irrigate the horse water every 2-3 days during the greening period, and use frequent irrigation and rowing to promote the growth of seedling roots;
[0024] (4) After entering the tillering stage, irrigate frequently with shallow water t...

The invention discloses a method for improving a rice planting environment when total straw is returned to a field. In the rice planting process, through the adoption of a nano-micron gas-liquid interface technology, nano-micron gas-liquid diffused phase water is added into rice irrigation water for rice irrigation, mixed water in the rice field is diffused and conveyed in different modes after the irrigation is stopped, and the nano-micron gas-liquid dispersed mixed water continues to be remained, so that the electric potential of soil colloid can be improved, the physical and chemical properties of soil are changed, the soil environment when the total straw is returned to the field is greatly improved, and the anaerobic effect of the soil when the total straw is returned to the field is alleviated and inhibited.
Description
technical field [0001] The invention relates to a method for improving the rice planting environment, in particular to a method for improving the rice planting environment by using nano-micron air-liquid interface technology. Background technique [0002] Rice is one of the most important crops in the world. The cultivation of rice not only plays an important role in food security, but also has an irreplaceable significance to the ecological environment. This requires not only the creation of excellent new varieties (combinations), but also the The improvement and optimization of cultivation techniques are practical and will not have any impact on the environment. [0003] In recent years, with the excessive use of chemical fertilizers in the process of rice planting, the soil has become compacted and it is difficult to loosen. It is easy to make the root system of the planted rice lack oxygen, which is not conducive to the growth of rice. And with the continuous promotion ...
