Due to the climatic factors in Heilongjiang Province in China, the maturity of many crops will change. Therefore, when selecting high-yielding crops, it is necessary to rationally arrange the summer season based on the local meteorological conditions so as to avoid the phenomenon of cross-region planting and cause unnecessary losses. Generally, it is possible to choose a variety that is 30-50°C less than the effective accumulated temperature in the region as a main plant variety. Therefore, soybean is a suitable high-yielding crop in the region, but it should also be selected for varieties with good quality, large potential for yield increase, and strong adaptability. Monitoring of soil moisture is always indispensable during the cultivation of various crops. This is because soil moisture has a direct impact on the growth and yield of crops. The soil moisture meter is an instrument that specifically measures soil moisture and plays an important role in modern agriculture.
Soybeans are sown in spring, when spring temperatures pass 8°C, sowing can begin. In addition to ground temperature, soil moisture is also an important factor limiting the sowing time. Therefore, the soil moisture content of the planting area should be determined by a soil moisture meter. From April 25 to May 20 in Heilongjiang Province, it is suitable sowing time for soybeans. When soybeans are sown in one area or one place, it depends on the length of the soybean variety and the soil moisture. Early varieties of late sowing, late-maturing early sowing; better soil moisture, late sowing, chilling worse, should be robbed sowing.
After sowing, the control of soil moisture is also very important. It is necessary to use the soil moisture tester to measure and strive to open the field drainage ditch in time after the whole seedling sowing, so that the ditch can communicate with each other, the drainage and irrigation can be smooth, the rainfall can not accumulate water, and the rottenness can be prevented. When the weather is dry and cannot be cultivated, watering should be done in time to make the soil moisture suitable for sowing. If the weather continues to be dry, watering will still be required after sowing, so as to prevent sprouting of bean sprouts due to dehydration.
During the growth of soybeans, the soil moisture content tester is used to measure the soil moisture content required for soybean growth and measures are taken at the appropriate time to ensure its normal and healthy production and development. After maturity, it also needs timely harvest to ensure the quality of the product. Harvesting of soybeans should be carried out in the yellow ripening period, and they should be transported to the yard for 5 to 7 days. After the completion of the ripening stage, the sun dried mills should be used for threshing. This way, the beans have less squash, broken and blue grains, good color, and high product quality. If they do not pile up after the end of the year, flattening, breaking, and slicing account for more than 1/3, which will obviously affect the quality of the goods.
