Soybean (having a scientific name of Glycine max (Linn.) Merr.) is an annual herb of genus Glycine of family leguminosae, and is 30-90 cm high. Native China and all parts of China are cultivated and are also widely cultivated all over the world. Soybean is one of the important grain crops in China, has been cultivated for five thousand years, is called Shushu in ancient times, and is a crop with seeds containing rich plant protein, wherein northeast China is the main production area. Soybeans are most commonly used for making various bean products, extracting soybean oil, brewing soy sauce, and extracting proteins.
During the growth and development of soybeans, the soybeans are influenced by a plurality of factors, and drought is one of the important factors influencing the growth and development of the soybeans.

3. The key point of this patent: (1) irrigating enough winter water, and raking and preserving soil moisture in early spring; raking and preserving soil moisture. The soil in the field becomes upper-deficient and lower-excessive, the evaporation of the water in the soil in the field is reduced, and the water is reserved in the soil plough layer.
(2) Selecting drought-resistant or drought-tolerant varieties of short stalks or semi-short stalks; selecting soybean varieties with short stalks or semi-short stalks and strong stalk resistance, lodging resistance, drought resistance and ecological adaptability. And selecting drought-resistant or drought-tolerant varieties. Such as: ningdou No. 6, No. 7, Jinyi 19, etc.
(3) Deep ditching to obtain moist soil; the sowing adopts ditching planting, the adaptive ditching depth is selected according to the actual condition of the soil moisture content of the field, and the deep ditching is mainly to ensure that seeds are sowed on wet soil. And (3) using a furrow opener to sow the seed furrow, wherein the depth of the seed furrow is 10-15 cm, the width of the seed furrow is about 20cm, and wet soil is found at the bottom of the seed furrow.
(4) Shallow sowing to ensure early and quick growth; and (4) carrying out hole sowing by using an inserting sowing device or a hand-push top box type duckbill precision sowing device. The row spacing of the seeds is 50cm, the hole is 13-14 cm, 2 seeds are planted in each hole, the seeds are sowed on the wet soil at the bottom of the ditch, and the sowing depth is 4-5 cm. The sowing depth and the sowing quantity are required to be consistent, and the sowing quality is ensured.
(5) Treading heavily to prevent water evaporation; after sowing, no soil is covered, and the soil is treaded with feet to prevent the water in the soil from evaporating and protect the soil moisture content. Ditching → sowing → continuous operation of trampling, reducing water evaporation, improving the water absorption and germination rate of seeds, and ensuring complete, neat and strong seedlings.
(6) Cultivating in the early stage to promote strong seedlings to grow early;
(7) reasonable irrigation is carried out, and the water requirement of the soybean in the flowering period is ensured; and (5) filling flower pod water. The water demand of soybeans is gradually increased in the flowering period, the water demand is the largest in the pod-bearing and grain-blowing period, and the yield is seriously influenced if water is lacked and drought in the period, so that irrigation is considered by combining the weather and the soil condition. Such as: furrow irrigation, furrow irrigation and spray irrigation. The water dropping amount of micro-irrigation and drop irrigation is preferably 6m each time3/667m2If 3 times is a flood irrigation period, 50-60 m of water resource can be saved3/667m2。
