Description

Soybean planting method

Technical Field

The invention relates to the technical field of agriculture, in particular to a soybean planting method.

Background

Glycine max (Leguminosae) belongs to annual herb, and is called Shushu in China, which is a leguminous plant rich in protein, and soybeans are oval and spherical, and have yellow, light green, black colors and the like, so that soybeans are called soybeans, green beans and black beans. The soybean is not only a delicious food on a dining table, but also has good nutritional value, the active ingredient isoflavone in the soybean has the effects of resisting oxidation, removing free radicals and the like, researches show that 30 60mg of soybean isoflavone taken every day can obviously reduce the content of cholesterol in blood, reduce the occurrence of arteriosclerosis, be conductive to improving body health and reducing the incidence of cancers, the lecithin contained in the soybean is an important part of brain cell composition, and the soybean has good effect of increasing and improving brain skills when being frequently eaten, so that the soybean demand in the market is more and more.

Soybean is cultivated in China and is widely cultivated all over the world. Soybean is one of the important grain crops in China, five thousand years of cultivation history exists, but in the current planting process, the germination rate of soybean seeds is low due to pest eating and the planting environment, and blind fertilization causes a large amount of resource waste and environmental pollution, more importantly, the utilization rate of chemical fertilizer is greatly reduced along with the continuous expansion of the quantity, and meanwhile, the phenomena of plant diseases and insect pests outbreak and lodging caused by the overgrowth of soybean branches and leaves are ubiquitous, various factors are integrated, the production cost of soybean is continuously increased, the yield cannot be improved, and the quality is gradually reduced. Therefore, a soybean planting method is an urgent problem to be solved.

Disclosure of Invention

The invention aims to solve the technical problem of a planting method for improving the yield of soybeans.

In order to solve the technical problem, the technical scheme provided by the invention is a soybean planting method, which comprises the following steps:

(1) Seed treatment: selecting improved autumn seeds, airing the seeds in a cloth bag for 1 day after selecting the seeds, then carrying out low-power ultrasonic treatment, and then mixing the soybean seeds with a rhizobium inoculant;

(2) Land preparation: deeply ploughing and preparing the soybean before sowing, applying organic fertilizer, repeatedly raking and crushing, leveling the land, and shallowly ploughing and cleaning stubble before sowing;

(3) Ridging: the width of each large ridge is 130 cm, the large ridges adopt a six-row seedling belt planting mode, the total width of the seedling belts is 80cm, and the distance between the seedling belts is 16cm;

(4) A sowing mode: sowing when the water content of the soil is 70-80% of the field water capacity, sowing at the depth of 2-3cm, carrying out equidistant precision dibbling by utilizing a soybean sowing machine to enable plants to be uniformly distributed, and calculating the seedling-plant spacing by adopting the following formula: total length (cm)/(hectare plants/hectare square meters ridge width (m)/row number of seedling strips);

(5) And (3) growth management: after the soybean seedlings emerge, seedling checking, seedling shortage and seedling supplementing are carried out, the seedling completeness is ensured, seedlings are thinned in time, pimple seedlings are removed, the seedling completeness and the seedling robustness are achieved, and the seedling supplementing or bud seedling transplanting can be carried out during the seedling supplementing; cultivating and weeding immediately after thinning, cultivating for 3-4 times at least in the whole growth period, and cultivating according to the growth condition of the root system from shallow to deep and then shallow; spraying chlormequat chloride solution when 4-6 leaves of the soybean exist, spraying chlormequat chloride solution once in the initial flowering period, and spraying imidacloprid once about twenty days after emergence of seedlings; spraying abamectin and imidacloprid twice from blooming to podding and between the drum grains.

As an improvement, in the first step, the mixing ratio of the rhizobium inoculant to the soybean seeds is 1.

In the fourth step, the error of the total width of the seedling belts is not more than 10cm, and the error of the spacing between the seedling belts is more than 2cm.

Compared with the prior art, the invention has the advantages that: the planting method of the soybeans is easy to implement, does not have complex operation, has strong application and popularization values, can improve the yield of the soybeans, obviously improves the economic benefit of planting, can improve the quality of the soybeans, and is beneficial to the healthy development of the soybean industry.

Detailed Description

Example 1: a soybean planting method comprises the following steps:

(1) Seed treatment: selecting improved autumn seeds, airing the seeds in a cloth bag for 1 day after selecting the seeds, then carrying out low-power ultrasonic treatment, and then mixing the soybean seeds with a rhizobium inoculant at a mixing ratio of 1;

(2) Land preparation: deeply ploughing and preparing the land of the soybeans before sowing, applying organic fertilizer in combination, repeatedly raking and crushing, leveling the land, and shallowly ploughing and cleaning stubbles before sowing;

(3) Ridging: the width of each large ridge is 130 cm, the large ridges adopt a six-row seedling belt planting mode, the total width of the seedling belts is 80cm, the error of the total width of the seedling belts is not more than 10cm, the interval of the seedling belts is 16cm, and the error of the interval of the seedling belts is more than 2cm;

(4) A sowing mode: sowing when the water content of the soil is 70-80% of the field water holding capacity, sowing at the depth of 2-3cm, carrying out equidistant precision dibbling by using a soybean sowing machine to ensure that the plants are uniformly distributed, calculating the seedling-plant spacing by adopting the following formula, and taking 1 meter long as a calculation unit and 24 ten thousand plants per hectare: 100 cm/(240000/10000 × 1.3/6) ≈ 19.23cm;

Example 2: a soybean planting method comprises the following steps:

(1) Seed treatment: selecting autumn-turning improved seeds, airing the seeds in a cloth bag for 1 day after the seeds are selected, then carrying out low-power ultrasonic treatment, and then blending the soybean seeds with a rhizobium inoculant at a blending ratio of 1;

(4) A sowing mode: sowing when the water content of the soil is 70-80% of the field water capacity, sowing at the depth of 2-3cm, carrying out equidistant precision dibbling by utilizing a soybean sowing machine to ensure that plants are uniformly distributed, calculating the seedling-plant spacing by adopting the following formula, taking 1 meter long as a calculation unit, and taking 36 thousands of plants per hectare: 100 cm/(360000/10000 × 1.3/6) ≈ 12.82cm;
