Description

A method of sowing Vetch based on Vetch-rice crop rotation

technical field

The invention belongs to the technical field of agriculture, and in particular relates to a method for sowing vetch based on vetch-rice rotation.

Background technique

Vetch belongs to the leguminous Astragalus crop, and is the main winter green manure crop in paddy fields in southern my country. Vetch-rice rotation is a resource-efficient and ecologically-friendly planting model. Studies have shown that Vetch-rice rotation can reduce the amount of chemical fertilizers, increase rice yield, increase paddy soil nutrients, and improve the physicochemical and biological properties of paddy soil. traits.

The traditional sowing method is to intersow vetch on the bottom of the rice, that is, when the rice is mature, the vetch seeds are sown in the rice field where the rice is still growing. In this way of planting, the planters need to walk through the rice fields. The dense rice paddies slow down the traveling speed, increase the labor intensity and reduce the labor efficiency. More importantly, with the continuous development of agricultural technology, more and more rice is harvested by machinery, and the current mechanical harvest rate has reached more than 90%. On the one hand, due to the high humidity in the field, the vetch seedlings were crushed to death by the harvester, and the seedling rate was only 30%; on the other hand, the straw produced during harvesting would cover the vetch. The above factors make the above-mentioned sowing methods no longer suitable, and new methods of sowing vetch are urgently needed in the technical field.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an efficient method for sowing Vetch, so as to solve at least one of a series of technical problems caused by mechanical harvesting of rice in the case of Vetch-rice rotation.

In order to accomplish the above-mentioned purpose, the present invention provides a kind of vetch seeding method based on vetch-rice rotation, comprising the following steps:

1) harvesting rice;

2) sowing vetch seeds;

3) Use the rice stubble stubble machine to stubble.

In some embodiments of the present invention, the harvesting of rice in step 1) refers to mechanical harvesting.

In some embodiments of the invention, the mechanical harvesting refers to low stubble harvesting.

In some preferred embodiments of the present invention, the low stubble means that the height of the rice stubble after the rice is harvested is not higher than 10 cm.

In some more preferred embodiments of the present invention, the low stubble means that the height of the rice stubble after rice harvesting is not higher than 5 cm.

In some embodiments of the present invention, the sowing in step 2) refers to broadcasting.

In some specific embodiments of the invention, the broadcasting is manual broadcasting.

In other specific embodiments of the present invention, the broadcasting is mechanical broadcasting.

In some embodiments of the present invention, the seeding rate of Vetch is 1.5-2 kg/mu.

In some preferred embodiments of the present invention, the seeding rate of Vetch is 1.0-1.5 kg/mu.

In some more preferred embodiments of the present invention, the seeding rate of Vetch is 1.25 kg/mu.

The beneficial effects of the present invention

Compared with the prior art, the present invention has the following beneficial effects:

1. Sowing seeds in the open space after harvesting reduces labor intensity and improves labor efficiency. The sowing efficiency is increased from 20 mu/day to 50 mu/day.

2. After the stubble is eliminated, the rice straw is no longer piled up, and is evenly spread on the surface, and the Vetch seedlings can be drilled out.

3. After using the stubble stubble machine, the Vetch seeds scattered on the rice straw will sink to the ground due to the action of gravity and fully contact the ground.

4. The distribution of Vetch seeds is more even after stubble removal.

5. The straw is evenly covered on the surface, which has the function of protecting moisture and heat preservation.

6. Save 40% of vetch seeds.

7. Increase the yield of vetch seeds by more than 30%; increase the yield of fresh vetch by more than 25%.

Detailed ways

In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below with reference to the embodiments.

Example

The following examples are used herein to demonstrate preferred embodiments of the present invention. Those skilled in the art will appreciate that the techniques disclosed in the following examples represent techniques discovered by the inventors that can be used to implement the present invention, and thus can be regarded as preferred solutions for implementing the present invention. However, those skilled in the art should understand from this specification that many modifications can be made to the specific embodiments disclosed herein and still obtain the same or similar results, without departing from the spirit or scope of the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, the public references herein and the materials to which they refer are incorporated by reference .

Those skilled in the art will recognize, or be aware of through routine experimentation, many equivalents to the specific embodiments of the invention described herein. Such equivalents are to be included in the claims.

Example

The present embodiment provides a method for direct seeding in paddy fields using stubble removal after rice, and the specific operations are as follows:

For mechanical harvesting of rice, since there is no interplanting of vetch, it can be harvested with low stubble. In this example, the height of the rice pile after harvesting is about 5 cm.

After the rice is harvested, choose fine weather, sow the Vetch seeds in the field after harvesting, the seeding rate is 1.25kg/mu, and then use the rice stubble stubble machine to eliminate the stubble.

The comparative example is the traditional method of interplanting Vetch on the bottom of rice, and the seeding amount is 2kg/mu. After the Vetch is grown together with the rice for 10 days, the rice harvester is used to harvest the rice with high stubble. The rice pile is about 20cm high.

The results showed that although the seeding rates were different, the survival numbers of Vetch seedlings per unit area were almost the same, and there was no significant difference, indicating that the method of direct seeding in paddy fields after rice stubble could save nearly 40% of seeds.

After harvesting, the seed yield and fresh grass yield were counted, and the results were shown in Table 1 and Figures 1 and 2. It can be seen that the yield of the method of direct seeding in the paddy field after rice stubble is significantly higher than that of the method of interplanting the bottom of the rice, the seed yield is increased by more than 30%, and the fresh grass yield is increased by more than 25%.
