Shandong big growers teach you 7 skills to grow the best soybeans.

Soybean is one of the most important oil crops in China. Shandong soybean is famous in China. Shandong Province has a unique advantage in the breeding of improved soybean varieties and has a stable soybean seed production base all the year round. Its improved varieties are exported to most of Shandong, Henan, Jiangsu, Anhui, Shanxi, Hebei and other provinces hundreds of counties and cities, known as hybrid beans, become famous brand products in the Yellow and Huaihe River Basin. The high-yield cultivation technique of soybean is one of the important technical measures to obtain high yield. In order to obtain a higher yield level, the combination of improved varieties and methods must be implemented in order to achieve the goal of high yield and bumper harvest.

First, sowing at the right time: the area of spring soybean is small, and its sowing is mostly controlled flexibly by stubble and interplanting. Summer soybean: summer soybean is generally direct seeding after wheat, which can be arranged by planting stubble in various places, and it is suitable for Shandong Province from late May to the first and middle of June. The varieties suitable for maize intercropping and intercropping: the soybean varieties suitable for maize-soybean intercropping must have four characters: early maturity, short stalk, limited podding habit and strong negative tolerance.

Second, reasonable close planting: the planting density should be determined by the variety characteristics of local climate and soil fertility. Early sowing should be sparse, late sowing should be dense; fertile land should be sparse, thin land should be dense; high-yield fields should be sparse; low-yield fields should be dense. The general planting density between early-maturing varieties and late-maturing varieties should be determined by the number of branches, that is, those with more branches, tall plants and high productivity per plant should be sparse, and vice versa.

Third, sowing with sufficient moisture: sowing with sufficient moisture is the key to sowing the whole seedling, and it is also an important measure to win the level of high yield. it is strictly forbidden to sow seeds under moisture and irrigate with planting water (masked water).

Fourth, seedling stage management: 1, and time seedlings, it is appropriate to fix seedlings at two-leaf stage in inter-seedling stage. 2. Hoe and weed in time. (chemical weeding is the best way to control weeds.) 15-20 kg of nitrogen, phosphorus and potassium compound fertilizer is applied per mu at seedling stage.

Fifth, early flowering stage management: early flowering stage is an important period of field management, whether the management is proper or not has a great impact on yield. The first measure is to prevent drought. Soybean is dry in most years from seedling stage to early flowering stage, so it must be watered in time in case of drought. Soybean needs a large amount of nitrogen fertilizer, although soybean rhizobium has the effect of nitrogen fixation, but it can not meet the high yield level. Therefore, the application of 5-7 kg urea per mu at the early flowering stage is an extremely important technical measure.

6. Mid-term management: the period from flowering to podding is mainly for the control of insect pests. Shandong Province is generally the key control period in late August and early September. Shandong farmers encounter problems related to planting soybeans and like to consult experts on the "Cloud cultivation" platform, which is the world's largest agricultural technology question and answer website. It brings together tens of thousands of planting and farming experts, and every question raised can be answered within 2 minutes.

Harvest and preservation: after the soybean harvest, it is necessary to cool the sun on behalf of the plant to prevent the fried waist and fading of the beans. When the moisture content of the seed is less than 12%, it should be threshed in time and stored in a cool sun. Keep soybeans after harvest to prevent rain and mildew, and it is strictly forbidden to knock and thresh on the road.
