Early-maturing soybeans are favored by farmers and consumers due to their low production cost, easy cultivation, and rich nutrition. In our cultivation, we should promote the use of the word "early", that is, to select early-maturing varieties and sow early morning market, which is good. Now we will introduce the cultivation techniques of early-maturing soybeans as follows:
(1) timely morning broadcast in the morning market: mulching can be planted in early March;
(2) Variety selection: It is advisable to promote Liaoxian No. 1, Taiwan 75, early-born 75 and other varieties in our country;
(3) Reasonable dense planting: A reasonable close planting has an important effect on increasing the number of pods, promoting the fullness of beans, and increasing the yield. Generally, about 30,000 mu plants are planted at a spacing of 2023 cm and 2-3 seeds per hole are planted. Hey.
(4) Increase the application of phosphorus and potassium fertilizers: Phosphorus and potassium fertilizers are generally based on basal fertilizer, supplemented by topdressing. The basal fertilizer generally applies domestic compound fertilizer 100kg and plant ash 100-150kg. In the seedling stage, rhizobia have not yet formed, and 10% of human fecal urine can be applied once; if the growth is not good before flowering, 10-20% of human fecal urine can be topdressed 2-3 times, and 0.3-0.5% urea can also be topdressed. Timely top dressing can increase production and improve quality.
(5) Scientific Irrigation: The moisture requirement of soybeans differs depending on the growth period. When sowing, the water is sufficient, the germination is fast, the emergence is quick and homogeneous, and the seedlings grow robustly. In mid-April, when the temperature is stable above 18 degrees, the cover film should be removed and irrigation should be performed according to the dry and wet conditions of the soil to ensure the growth and development of green soybeans. Pre-harvest period and flowering and podging period, should not be too dry and wet soil, otherwise it will affect flower bud differentiation, resulting in reduced flowering, flower buds fall off.
(6) Pest control: The pests of green soybean mainly include soybean meal, ground tiger and leaf-feeding pests (bean worm, etc.). For soybean meal and ground tiger, 90% trichlorfon (800 to 1000 times) can be used to prevent and control 75 kg/mu of liquid medicine; leaf-feeding pests can use 2.5% Kung Fu EC to dilute 30 ml of water per mu. The liquid 75kg. The diseases of green soybean are mainly mosaic virus disease and downy mildew. The mosaic virus disease is mainly selected from disease resistant varieties and non-toxic seeds; the control of downy mildew is 500 times per acre with 500 grams of toxic liquid and 75 kg of fog. Times, about 15 days apart.
(7) Harvesting: Early-maturing varieties generally grab the morning market, that is, after entering the drum grain period, they can be gradually harvested, but they can't blindly be greedy as early as possible, otherwise the beans are small, the commodity is poor, and the yield is low, but the economic benefit is reduced. . Harvesting can be divided into 2-3 times, which can increase production and increase efficiency. After harvesting, keep it in a cool place to keep it fresh.
