Master these skills of fertilizing soybeans to double your yield!

As one of the food crops of traditional Chinese medicine, soybean is widely planted all over the country, and soybean growers are most concerned about yield, price and subsidy. Here are the skills of fertilizing soybeans, which can double your yield.

I. the basic situation of soybeans

1. Soybean is an annual herb native to China, also known as soybean and soybean. Now soybeans are widely cultivated all over the world, and sin is most commonly used to make all kinds of soybean products, extract soybean oil, brew soy sauce and extract protein.

two。 In addition to the high nutritional and edible value of soybean, which can promote intestinal peristalsis, help defecation, prevent constipation and prevent colorectal cancer, soybean also has high utilization value in medicine, feeding and industry. In medicine, soybeans can reduce edema, treat swelling and poison, prolactin, stop bleeding, etc.; in feeding, the feed made of soybean meal is a good high-quality protein feed for raising livestock; the soybean oil extracted in industry can be used as edible oil. in addition, it can be used as automobile painting, outdoor paint, food processing and so on.

What kind of fertilizer should be used to grow soybeans?

Before you know the skills of fertilizing, you should find out which fertilizers should be used in the process of planting soybeans.

1. Application of base fertilizer: also known as base fertilizer, generally before sowing or transplanting, it is mainly to supply the nutrients needed during the whole growing period of plants, to create good soil conditions for crop growth and development, and to improve soil and fertilize soil fertility. On the other hand, the application of base fertilizer is beneficial to nodulation and nitrogen fixation and increase the yield of soybean.

two。 Application of seed fertilizer: seed fertilizer refers to the application of fertilizer near or mixed with seeds to provide nutrients for the early growth of crops during sowing or transplanting. Generally, 10 kg to 15 kg superphosphate or 5 kg diammonium phosphate can be used as seed fertilizer per mu of soybeans, and 0.4 kg to 0.6 kg of borax can be added to boron-deficient soil.

3. Timely topdressing: topdressing is a fertilizer used to supplement and regulate plant nutrition during plant growth, mainly to supplement the deficiency of base fertilizer and to meet the nutritional needs of plants in the middle and later stages.

What are the skills of fertilizing soybeans?

1. The application of base fertilizer is the basis of high yield of soybean, so it is necessary to increase the yield of soybean. The base fertilizer mainly includes all organic fertilizer, phosphate fertilizer and part of nitrogen fertilizer. If the land is deficient in potassium, potassium fertilizer should be applied in advance.

The amount of organic fertilizer applied to soybean is about 200kg per mu, and phosphate fertilizer can be combined with ordinary calcium and phosphate rock powder. Phosphate rock powder was ditched and applied to the deep layer to meet the growth needs of soybean during the whole growth period. Planting soybean on low fertility soil can add 10 kg of superphosphate and 10 kg of potassium chloride as base fertilizer, which is beneficial to the yield of soybean.

two。 Seed fertilizer is mainly the fertilizer applied together when sowing soybean seeds, which can provide enough nutrients for soybean germination. Although the seed fertilizer is applied together with the seed, it should be noted that the seed fertilizer is not in direct contact with the seed, otherwise it is easy to burn seedlings. When applying fertilizer, the fertilizer should be applied at a depth of about 4CM under the seed, or at a distance of about 6CM from the seed.

Generally, the application methods of seed fertilizer are stratified fertilization and mechanical stratified deep fertilization. The fertilization depth of the upper layer is about 7CM, and that of the bottom layer is about 15-20CM.

3. The topdressing of soybean needs to be divided into several stages:

(1) Seedling stage: proper application of nitrogen fertilizer can make the plant grow healthily, and urea topdressing per hectare 75kg can promote the plant growth at the seedling stage.

(2) early flowering stage: a small amount of nitrogen fertilizer can be applied as appropriate, and the appropriate amount of nitrogen fertilizer is 7.5 to 10 kg urea per mu.

(3) flowering: spraying 0.2% to 0.3% potassium dihydrogen phosphate solution or calcium superphosphate water root can increase the nitrogen content of grain and increase yield obviously; in addition, spraying 0.1% borax, copper sulfate and manganese sulfate aqueous solution at flowering stage can promote grain fullness and increase soybean oil content.

4. In addition to the fertilization techniques introduced above, some foliar fertilizers can also be applied in the process of soybean planting, and fertilizers with high contents of trace elements such as boron, molybdenum and zinc can be selected. the best application period is the flower and pod stage, which is generally sprayed every 7-10 times. it's enough to spray twice during that time.

In fact, if you want to grow high-yielding soybeans, fertilization alone is not enough, such as weeding, watering, and the selection of good varieties are also indispensable. Therefore, if you want to achieve real high yield, it is best to achieve "all-round development and consideration", so that your soybean output can definitely double!
