Method for improving planting environment during total straw returning to field

Abstract

The invention relates to the technical field of rice planting, in particular to a method for improving a planting environment during total straw returning to a field. The method for improving the planting environment during total straw returning to the field comprises the steps that a nano-micron gas-liquid dispersion mixed water body is used for steeping the field for 3 or more days before rice planting, and then the inner part of the field is divided through a dividing net to form a plurality of planting areas with uniform sizes; then part of nano-micron gas liquid is evenly bound to the surface of the dividing net through a plurality of sealing bags, the intervals of the sealing bags are the same, protruding points are arranged on the surface of the dividing net, the depth of the dividing net inserted into land is 3-5 cm larger than the rice planting depth; and then irrigation pipes are evenly laid in the planting areas. The method for improving the planting environment during total straw returning to the field has the beneficial effects that under the condition of total straw returning to the field, the proper nano-micron gas-liquid dispersion water body for improving the soil reduction state is provided for irrigation, and compared with conventional irrigation, the oxidation-reduction potential of rice field soil subjected to total straw returning to the field is improved by 30 mV or above, dissolved oxygen in irrigation water is improved by 30% or above, and the number of white roots of rice is increased by 20% or above.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for improving the planting environment when all straw is returned to the field. 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 of returning full amount of straw ...

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.
