How to solve the bottleneck of soybean planting with low yield and low production enthusiasm of farm

During the growth process of soybean, its rhizome will metabolize alkaline substances, which will be difficult to digest and absorb by the next crop and molybdenum salts in the soil. In addition, soybean curd disease contains a lot of nitrogen, and the presence of nitrogen in land resources will reduce the proportion of other elements in the soil layer. Therefore, try not to plant soybeans in continuous stubble, because continuous planting will make the second soybean contain nitrogen and lack phosphorus, potassium, molybdenum and other elements, which greatly reduces the nutrient content of soybean.

In addition, most of the pests and diseases of soybeans have a certain selectivity, and soybeans are planted in succession.

It will increase the probability of pests and diseases, resulting in unnecessary losses. And stubble planting can minimize the impact of this bad factor. Generally, the growth and development stage of soybeans should be in the rainy season.

Rainfall is concentrated in the soybean growing season, which is crucial. In particular, summer soybeans in the Huanghuai region and spring soybeans in North China. Soybean growing season accounts for more than 60% of the annual rainfall, and the rainfall is not so balanced.

This is not conducive to the good growth and development of soybeans. Soybean planting should be carried out immediately after the removal of the compartment ditch, waist ditch and surrounding ditch.

In order to prevent flooding caused by the hard bottom of the soil layer due to sudden heavy rainfall. After the rain and sunny weather, it can loosen the top layer of soil and help soybeans sprout. Soybean production is correlated with the level of pests and diseases and weed production.

No matter how well soybeans grow and develop, if pests and weeds occur, it will cause greater harm to the production. In soybean production, underground pests should be effectively prevented. Soybean diseases and insect pests mainly include gray spot disease, sclerotinia sclerotinia and so on, which can be sprayed with pesticides and fungicides from the early stage of pests and diseases.

In the selection of seeds, it is necessary to select excellent varieties.

Try to choose high-frying, high-protein food bean seeds, only in this way can we ensure the purity and purity of the seeds and improve the germination rate. In addition, it is also necessary to ensure that the seeds are selected according to the specific local conditions, and the excellent varieties suitable for local cultivation are selected. In the second half of the soybean crop, it is necessary to carry out a thorough weeding work.

The growth and development of wild grasses not only absorbs the water and nutrients pre-buried by the soil layer and chemical fertilizers, but also affects the reproductive function and development standards of soybean crops in the middle and late stages. Generally, when soybean crops gradually set podding, it is the link where weed seedlings and grass seeds gradually grow abundantly, and this is the best period for hoeing and remediation.

In order to solve the bottleneck of soybean planting, we must first improve the planting technology, increase the yield of soybeans, and at the same time solve the problem of sales, so as to better develop the soybean industry.

Mainly because of the relatively low **, the yield of soybeans can be increased, and this problem can be better solved.

Because soybeans are very troublesome to grow, the requirements for soil and temperature are very high, and the profit of soybeans is relatively low, so farmers are not willing to spend too much time planting. The survival rate of soybeans is quite high, but the profit is relatively low compared to other crops, because the unit price cannot go up.

Because soybean planting is more difficult and the survival rate is low, the cost of planting is high, but the income is very small, resulting in most people are reluctant to plant soybeans; The survival rate of soybeans is relatively low.

It is mainly related to the enthusiasm of farmers, some farmers do not have the ability to master the technology of planting soybeans, and such a situation will occur, and the survival rate is not low.

You can water the soybeans more, apply more chemical fertilizers, and spray them with insect control drugs in advance, so that the soybeans planted will have a very high yield.

Management of soybean seedlings (mid-June to mid-July, about 20 days).

In the soybean seedling stage, it is necessary to timely seedlings and seedlings. Interseedling refers to pulling out excess seedlings after all seedlings are gathered, and weak seedlings and diseased seedlings are eliminated. Seedling determination refers to the last 1 seedling according to the predetermined row spacing and the number of seedlings left. Generally, seedlings are interplanted 2-3 times.

Soybean seedlings can generally increase the yield by 15%-20% compared with non-seedlings, especially in the years with large sowing amount, fertile soil and more rain. Soybean seedlings should be carried out sooner rather than later, generally after the soybean cotyledons are exposed to the ground and when the cotyledons are opened. Deep cultivation and weeding can reduce the consumption of soil nutrients by weeds, and at the same time can cut off the soil capillary, protect moisture and prevent drought, loosen the soil to promote root development, and have the effect of cutting roots to control vigorous growth.

Pay attention to the control of bean straw flies, aphids and red spiders.

1. Apply sufficient base fertilizer to cultivate strong seedlings. Soybean seedlings need certain nutrients to grow, and N, P, and K should be added as basal fertilizer before sowing to help strengthen seedlings and resist diseases. Generally, about 20kg of ternary compound fertilizer is applied per mu, or 1500-2000kg of decomposed organic fertilizer is applied as base fertilizer.

2. Seed fertilizer is generally 10 kg to 15 kg of superphosphate or 5 kg of diammonium phosphate per mu as seed fertilizer, and borax is added to borax to kg of boron-deficient soil. 3. Appropriate topdressing. Nitrogen topdressing at the early flowering stage can promote the development of flowers and the growth of young pods.

Generally, 4-5kg of urea per mu is sprinkled while it rains, and the plant can be reduced or not applied as appropriate if the plant grows too vigorously. Ammonium molybdate or superphosphate aqueous dilute solution can also be sprayed on the foliar surface of soybean seedling and early flowering stage respectively to improve fertilizer efficiency and increase yield. From the first flowering of soybeans to the pod-setting and grain bulging stage, if the weather is dry, it should be watered at the appropriate time to prevent the yield from being affected by drought.

In the early stage of soybean growth, due to the reason of root growth, it can only absorb fertilizer and water within about 10 cm of soil, and the fertilizer and water below 20 cm are used very little, and at the pod setting stage, with the deep rooting of the root system, the fertilizer within 10 cm is rarely reused, so it is necessary to pay attention to layered fertilization when fertilizing, both to apply basal fertilizer, but also to apply seed fertilizer, but also to apply flower pod fertilizer, pod fertilizer, we must pay attention to fertilizer and water management, increase yield.

Techniques for selecting pre-stubble planting. Generally speaking, it is very important to plant soybean crops, and the soybean fertilizer can ensure that soybeans absorb all kinds of fertilizers left by the previous crops during the growth process, and the crop crops suitable for soybean planting are corn, wheat, etc. Don't look at this inconspicuous front stubble, use the yield of cutting acres to increase by about 10.

Introduction: I don't know if you like to eat beans in your daily life, you will find that there are all kinds of soybeans sold in supermarkets or grain and oil stores. And every year in China, the demand for soybeans is also very large, so why do many farmers choose to plant soybeans?

Maybe friends like to eat some beans in their daily life, and there are many ways to make legumes. Therefore, our country's demand for soybeans is very large, but according to relevant data, most of China's soybean resources are imported. The reason why many farmers do not choose to plant soybeans is related to its planting cost.

Because in the process of planting soybeans, there are many processes required, and it is also more troublesome in the process of planting. Once the planting cost is relatively high, the income of farmers may be reduced, and many people are reluctant to plant Dabu dry beans at this time. <>

In addition to the high cost of soybean planting, there is also the biggest reason because the yield cannot meet everyone's needs. Farmers and uncles must sell soybeans for money in the process of planting soybeans, but if the harvest is not good, it will definitely affect their income. Once everyone finds that the yield of soybeans is not particularly good, no one will choose to plant soybeans early.

Therefore, you will find that many farmers may choose to grow rice or some other types of crops. <>

I believe that after seeing the introduction, everyone also knows why our country chooses to import soybeans. Because in the process of soybean planting, it needs to consume a lot of manpower and material resources. Some soybeans may have a lot of weeds or pests during the growth process.

At this time, weeding and pest control costs a lot of money. For farmers, this process is very tedious and requires them to spend a lot of money. Therefore, you will find that many people are reluctant to grow soybeans, so the country chooses to import soybeans from various places.

Soybeans also play many roles in daily life, whether they are used for oil extraction or other purposes.

The yield of soybeans is relatively low, and if it is planted on a large scale, the output of other grains will also be reduced, which will still have an impact.

Because the land is limited, soybeans cannot be grown for other grains, and the income from growing soybeans is relatively small.

Because it will cost a lot of money to do so, but imported soybeans are relatively cheap, and relatively speaking, they are more cherished and affordable.

<>In this limited arable land resources, we must first consider the four major staple grains, namely rice, wheat, corn, and potatoes, which are food crops that maintain the normal life of the people, while soybeans belong to miscellaneous grains. Every year, the state has to adjust the planting area of the four major staple grains according to the cultivated land resources and grain demand, and then make planting arrangements for small miscellaneous grains. Therefore, China has always been in a situation of insufficient food self-sufficiency.

Especially for soybean crops.

Soybeans are known to be the main oil crop and also an animal feed crop. Our country has a population of more than one billion, with the improvement of consumption level, the demand for grain and oil is increasing year by year, and the demand for soybean meal in the aquaculture industry is also increasing. In this case, the production of domestically grown soybeans is simply not enough, and soybeans must be imported from abroad to ease the tension between supply and demand.

Farmers are not highly motivated to grow soybeans. At this stage, the main problem is that the yield of soybean planting is low, and the economic benefits are not high.

Poor disease resistance and herbicide resistance of native varieties make field management difficult. Mechanization utilization rate is low. Now, although the state has increased subsidies for soybean planting and production has increased, the demand gap is still very large.

Therefore, China has always grown soybeans, but with the expansion of global soybean production, China's soybean planting accounts for less and less of the world. The consumption of staple foods is diversified, resulting in too much demand. Soybeans are crops, which can not only be used to press soybean oil, but also to make bean sprouts, soybean milk, tofu, etc., and can also produce soybean meal, a by-product of oil extraction.

Since the reform and opening up, people's living standards have been continuously improved, and the concept of catering consumption has changed.

China's dependence on imported soybeans and China is one of the world's major soybean producers, is a coexisting situation, not that China does not grow soybeans, on the contrary, it is the largest producer of non-genetically modified soybeans. The low yield of domestic non-GMO soybeans is the status quo, and due to various reasons, domestic edible soybeans are non-GMO, so the yield per mu leads to high costs. This is due to the low supply of soybeans planted in the market due to the cost of imported soybeans.

Because soybean planting has many requirements for land, temperature, weather, sunshine and moisture, there are many places that are not suitable for planting soybeans, so China's output is not so much, and many need to rely on imports.

Because foreign imports of soybeans will be cheaper, and import and export are mutual, and it is also a way of showing friendly ties between countries.

This is because corn and wheat are the basic crops for our country, so we cannot give up these and grow soybeans.
