Second, chemical weeding chemical weeding can increase production by 20%. Before sowing, the soybeans are sprayed evenly on the surface with 45% Beanweed Emulsion 80-100 ml or 50% Hebao Emulsified Oil 60-80 ml per acre. In the soybean growth period, 70 to 130 ml of 25% of the water is used per acre, or 10.8% of the high-efficiency grass can be used for stem and leaf treatment. 3. Drought-resistant and soaking soybeans are both afraid of drought and are not resistant to waterlogging. They are very sensitive to water reaction during the flowering stage. This requires the soil to remain slightly moist. If it is prolonged or even rainy, it will cause serious death. Therefore, in the case of dry weather, it should be shallow and drought-resistant. In the case of rainy weather, attention should be paid to the ditching and drainage work to prevent waterlogging in the field and ensure that the rain stays in the field. 4. Sparse the yellow leaf soybean into the mature stage of filling, and then remove the old yellow leaves in the middle and lower parts to prevent the field from being closed and avoid falling pods. When 70% of the pods are full, the leaves can be removed to promote fullness and maturity. 5. Flowering and pod-forming fertilization is best for pre-flowering or early flowering. Generally, 4 to 5 kg of urea is applied per mu, and 0.2% potassium dihydrogen phosphate and 0.05% ammonium molybdate mixture can also be used for foliar spraying, generally spraying 1 or 2 times. 6. Spraying paclobutrazol If the plant is long and canopy, spraying with paclobutrazol 150 mg/kg or 200 mg/kg during the initial flowering period can inhibit plant height, control internode elongation, and reduce growth rate. 7. Spraying insects in time to prevent insects During the pods, the leaves grow green and are vulnerable to a variety of pests. The use of 25% insecticidal double 200 grams of water 50 kg, sprayed on pods and leaves, can effectively control the pods The hazards of cockroaches, heartworms and mites.

Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.

First, when the seedlings are topped out, the Bean Seedlings grow 4 to 5 true leaves, and the growth point of the bean seedlings is removed, which not only effectively prevents the plants from growing and lodging, but also facilitates the grain filling and ripening. However, when picking the heart, it is necessary to pay attention to the fact that the soil layer is thick and the fertility is good, the land is thin, and the soil with poor fertility cannot be picked; the bottom fertilizer can be harvested and the harvest is insufficient. 
Soybean field management promotes high-yield technology analysis
For soybeans, I believe that everyone is no stranger. Soybeans occupy a pivotal position in China's agriculture. Many of the products are made of soybeans. Today, Xiaobian mainly introduces how to strengthen management techniques for improving soybean yield.
