1, according to the species close planting. In accordance with the principle that fertile land should be thin, and thin soil should be dense, branches with many varieties should be thin, and the main stem with cicadas should be dense, the use of isometric on-demand should be used to create a reasonable group structure. The double dome LED surgical lamp adopt the new type LED cold illuminant as the illumination source of operating lamps, it is not only benefit for the rapid recovery of surgery illuminate parts, but also improved the doctors' working environment and efficiency extremely; the operation lamp adopts LED as the light source of shadowless surgical lamps, energy-saving effect is remarkable, besides it's energy consumption only be the one tenth of general inscandescent light, one second of halogen lamp;

2. Increase fertilization according to soil fertility. It is necessary to ensure that there is sufficient nutrient supply during the growth period of soybeans, and that the types, proportions, and periods of fertilizer supply are properly matched so that soybeans will grow vigorously before flowering and have a certain leaf area index, so that they can accumulate more organic matter and promote More flowering. The nutrients of flower buds after flowering are guaranteed, preventing greediness, reducing the loss of calyx, and increasing grain weight. In the fertilization type, farmyard manure should be used as a base fertilizer, especially pig manure, chicken manure and other fertilizers containing phosphorus and potassium are preferred. Combined with the application of phosphate fertilizer, the base fertilizer and seed fertilizer should be the main fertilizers during the fertilization period. According to the reproductive performance of soybean, the spraying fertilizer at the initial flowering stage or during the scab stage also has the effect of increasing flower and soil conservation.
3, according to the characteristics of climate irrigation. Soybean seedlings are to be seedlings and begin to have soil drought in the end of the cropping period. Regular irrigation is needed to promote the physiological activity of the plants and to accelerate nutrient absorption and operation.
4. Strengthen field management. Timely eradication of weed damage, timely prevention and treatment of plant diseases and insect pests, etc., to improve the cultivation conditions of plants and flower bud fertility conditions, can also play a role in increasing flowering and conservation and increase production.
