Why do many farmers mix soybeans with corn? What are the benefits of hybridization?

Because on the one hand, it can make greater planting value of limited land, on the other hand, it can make full use of the water, temperature, gas, light, illumination and other resources of the land, for example, soybean can fix and provide more nitrogen fertilizer nutrition for corn through the nitrogen fixation of its own roots, so as to make corn grow better, higher yield, etc., and for example, soybean can obtain higher yield and quality under the marginal effect of interplanting planting.

Many farmers mix soybeans with corn. so that they have better development.

Corn and soybean intercropping! Soybeans must cooperate with bacteria called nitrogen-fixing bacteria to absorb nutrients! Nitrogen-fixing bacteria convert nitrogen into amines in the air! So the soil is fertiliser.

Disadvantages of intercropping of corn and soybeans, inconvenient interplanting, inconvenient field management, and inconvenient autumn harvest.

The way of planting is inconvenient.

Soybeans are hired machinery to sow seeds, a single buckle, a seedling on a seed, a day sown 4 days of soybeans, soybeans are finished to plant corn in the field, at this time the machinery can not be used, the hands can only be planted manually, we dug a day of pits, only a piece of 15 acres of land, 4 ridges and a hook of corn planted. Intercropping is too inconvenient.

The second point is field management.

During the interplanting period, the ridge of corn can not be ploughed, the ridge is shallow, and the water content is when watering.

It is very small, especially prone to drought, and when ploughing and sealing ridges, the corn cannot be sealed in that trip.

No matter how long it is, the soybean is not as tall as corn in the later stage, a ridge of soybean near corn is not as good as the rest, corn is high to block shade, and soybean does not absorb enough light.

Herbicides for corn and soybeans.

Not the same, because there is no plough on the corn ridge, the grass can not be covered, it needs to be removed manually or herbicides, the price of labor is higher than that of herbicides, generally spraying herbicides, but the selection of herbicides, it is necessary to choose soybeans and corn, the range of options is very small, and the gains outweigh the losses.

Corn and soybeans are not the same as insects, corn is corn borer.

Soybeans are pod-boring insects, different insects use different pesticides, and the range of pesticide choices is also small.

Our kind of corn, in the ridge when chasing the last side of the fertilizer, not top dressing corn in the later stage of the fertilizer, this ridge can not be sealed, the fertilizer can not be chased, if you want to chase you have to dig manually, too labor-intensive.

The third point is the dilemma of the autumn harvest.

Soybeans and corn interplanting, generally choose to harvest soybeans, so that the corn is left, the maturity of the corn is also late, lonely in the field, there are hard-working people will take it home, or cattle and sheep are easy to eat, you have to watch every day, do other farm work.

There is some corn left, and no one can do it for the hired machinery, so they can only break it themselves, and no one will beat it when they go home, so they can only do it themselves.

After the soybean harvest is completed, the soybean stubble is very small, and it will be doubled or flattened in the coming year, and it will be neat and tidy.

Not scientific, not advanced! Returning to primitive farming is a stumbling block to the development of agriculture in Zhongyuan!!

The method of intercropping between corn and soybean, also known as soybean-corn strip compound planting, this planting model has a very good effect on improving the comprehensive yield of crops and increasing the overall income of farmers, because it can make greater planting value of limited land on the one hand, and on the other hand, it can make more full use of the land's resources such as water, temperature, gas, light, light, etc., for example, soybean can fix and provide more nitrogen fertilizer nutrition for corn through the nitrogen fixation of its own root nucleus**, As a result, corn can grow better and yield higher, and soybeans can obtain higher yield and quality under the marginal effect of interplanting.

The more compact the maize plant shape of the <> interspersed planting, the better the gout of soybean in the field, the higher the plant height, the thicker the stem and stalk, and the higher the yield in the later stage. If corn is sown early, the yield and quality of soybean will be higher. Sowing soybean late will be more conducive to full and strong seedlings; Appropriately expanding the row spacing of corn and increasing the spacing between corn and soybean will make soybean yield higher in the later stage.

1. Corn and soybeans are planted together, because of the dense branches and leaves, covering the ground, which can inhibit the growth of weeds, reduce the evaporation of soil moisture, and improve drought resistance. Rhizobia parasitism on the roots of soybeans can absorb nitrogen from the air to make nitrogen fertilizers, some of which are absorbed by soybeans and some of which can be used to feed corn, so that the two crop species can grow together and produce much higher yields than a single crop.

2. Note: Because corn absorbs more fertilizer from the ground than soybeans, more corn can be planted on fertile land; On lean ground, you need a variety of soybeans. When intercropping, corn is generally planted in wide and narrow rows, and several rows of soybeans are planted in the wide rows. Or the corn is planted with wide rows and narrow plants, and a row of soybeans is planted between the two rows of corn in the Wheel Tomb Belt, which can get sufficient sunlight and air circulation.

At present, soybeans are still mainly imported from abroad. Purebred soybeans are good. The state is now focusing on the development of agriculture.

This year's soybean gains are very impressive! Then, compared to the traditional cultivation of purebred soybeans, soybean-corn multi-cultivation has more advantages and higher yields.

Soybean cultivation is highly profitable, and bumper harvests have been achieved everywhere. It is better to mix soybean and corn so that you can achieve a bumper harvest of both agricultural products.

Corn plants are tall, and after intercropping, they can better transmit wind and light, avoid canopy closure, and are conducive to corn growth. In addition, soybeans are short-day crops, and corn can just block some of the sunlight without affecting the ventilation and soybean growth. Corn has a well-developed root system and is able to penetrate deep into the soil to absorb more nutrients and water.

The root system of soybean is relatively shallow, that is, it is afraid of drought and waterlogging, and the drought tolerance of soybean can be improved after intercropping. In other words, even in a year of drought and little rainfall, a soybean harvest can be guaranteed and the yield will not be extinct. Cultivation Method:

Widen the distance between the corn belts, preferably at such a distance of meters. This allows the soybeans to get more light. In addition, it is recommended to sow soybeans in 4-6 rows, with a single seed sowing of 8-10 cm spacing.

It can play a complementary advantage, is conducive to enhancing the root development of corn, can ensure the harvest of potatoes, has the advantage of increasing yield, can avoid too dry situation, and promote nutrient absorption. It is important to know the planting situation, to ensure the nutrients of the soil, and to take into account the needs of the planting side, so that the yield can be guaranteed.

This can have a higher yield, is also good for the soil, can enjoy more food, large producers must operate according to the actual situation of the land, planting, pay attention to modern planting.

01 Corn is tall, likes sunlight, has shallow roots, mainly absorbs and uses nutrients from the upper soil, and needs more nitrogen fertilizer during the growing season. Soybeans, on the other hand, are more shade-tolerant, have deeper roots than corn, and can absorb and utilize nutrients in the underlying soil, requiring little nitrogen fertilizer, but requiring a lot of phosphorus and potassium fertilizers. Therefore, corn and soybeans are planted together, not only do not compete with each other for nutrients, but they are very compatible and can make full use of the land and sunlight.

When farmers grow corn, they often like to interplant with soybeans, why is that?

In fact, corn and soybeans are very compatible when planted together. The reason is that corn and soybeans are "kind-hearted".

Therefore, corn and soybeans are planted together, not only do not compete with each other for nutrients, but they are very compatible and can make full use of the land and sunlight.

Soybean roots have rhizobia parasitism, which can absorb nitrogen from the air and produce nitrogen fertilizer, which can be used to supply corn.

Summary. Corn and soybean rotations work well because they prevent pests and diseases while also enhancing soil fertility. In principle, the rotation of corn and soybean can effectively use soil fertility and cultivate soil fertility, which has the significance of reducing the occurrence of pests and diseases.

This crop rotation works very well, the model of Heilongjiang Province. Soybean stubble belongs to fat stubble, and it is good to plant anything, and it is better to plant corn.

This kind of rotation effect Qinghuai fruit is very good, the model of the black dragon cherry trembling Jiang Province.

Soybean stubble belongs to fat stubble, and it is better to plant anything than good stubble, and it is better to plant corn ridge.

The advantage is that soybean nitrogen fixation can be used for corn. 1.Many rhizobia in soybean roots improve soil fertility and allow Yuda Wuzi rice to make full use of it2

Use soybeans to suppress the growth of weeds3Make full use of the land and increase the yield 4Alleviate the contradiction of people's chaos and lack of cultivated land.

Corn and soybean are the most ideal crop rotation partners, and reasonable crop rotation and mutual crop exchange can promote each other's yield.
