The correct method of fertilizing soybeans.
Soybean is one of the important cash crops in China, which is of great significance for increasing farmers' income and ensuring national food security. However, fertilization is a very important part of the process of growing soybeans. The right fertilization method can promote the growth of soybeans and improve the yield and quality. This article will introduce the correct fertilization method for soybeans.
First, basal fertilizer application.
Basal fertilizer is the basis of soybean growth, which plays an important role in improving soil fertility and promoting soybean growth. The application of basal fertilizer should be adjusted according to soil fertility and soybean varieties. Generally speaking, the base fertilizer should be mainly organic fertilizer, with an appropriate amount of chemical fertilizer. Organic fertilizers can improve soil structure and increase soil fertility, while chemical fertilizers can provide the nutrients needed for soybean growth.
Second, fertilizer application.
Seed fertilizer is a fertilizer applied at the time of sowing, and its main role is to provide nutrients for soybean seeds and promote seed germination and growth. Seed fertilizer should be mainly phosphate fertilizer, with an appropriate amount of nitrogen fertilizer. Phosphate fertilizer can promote the growth and development of soybean roots, improve seed germination rate and stress resistance;Nitrogen fertilizer can promote the growth of soybean seedlings. The amount of fertilizer should be adjusted according to soil fertility and soybean varieties.
3. Top dressing application.
Top dressing is a fertilizer applied during the growth of soybeans, and its main role is to provide the nutrients needed for soybean growth and promote the growth and development of soybeans. Top dressing should be based on the growth of soybeans and soil fertility to determine the amount and time of application. Generally speaking, top dressing should be mainly nitrogen fertilizer, with an appropriate amount of phosphate fertilizer and potassium fertilizer. Nitrogen fertilizer can promote the growth and development of soybean stems and leaves, and improve the efficiency of photosynthesisPhosphate fertilizer can promote the growth and development of soybean roots and improve stress resistancePotassium fertilizer can promote the toughness and lodging resistance of soybean stems and leaves.
In the process of topdressing, the following points should be noted:
1.The amount of fertilizer should be appropriate, and do not over-fertilize, so as not to cause waste and pollution to the environment;
2.The fertilization time should be timely, not too early or too late, so as not to affect the growth and development of soybeans;
3.The fertilization method should be reasonable, and the method of fertilization can be carried out by strip application, hole application or spraying
4.After fertilization, it should be watered in time to promote fertilizer dissolution and absorption.
4. Precautions.
1.In the process of fertilization, it is necessary to pay attention to balanced fertilization, and do not apply a certain nutrient element, so as not to cause nutritional imbalance;
2.In the process of fertilization, it is necessary to pay attention to the growth of soybeans, and adjust the amount of fertilizer and fertilization time in time
3.In the process of fertilization, it is necessary to pay attention to the protection of the environment, do not litter and pollute the water source;
4.Pay attention to safety during fertilization and do not carry out fertilization operations in high temperatures or rainy days.
In conclusion, the correct fertilization method plays an important role in promoting the growth of soybean and improving the yield and quality. In the process of planting soybeans, the appropriate fertilization method and time should be selected according to the soil fertility and different soybean varieties, and attention should be paid to balancing fertilization and environmental protection.
