Soybean is the main fuel in our province. The development of soybean production is of great significance in improving the father’s food composition, developing animal husbandry, and rotating crops to improve soil fertility. From the actual situation in our province, soybean production mainly depends on increasing the yield to increase the total output. In order to achieve 200W per mu, there is no need to liberate the soybeans from the corn field, because the mixed soybean and corn is one of the reasons why I don't need soybean production in our province, so I need to clear the species; the second is to actively promote Sowing as the center, the application of high-yielding cultivation techniques based on agricultural fertilizer and phosphate fertilizer; the third is based on different ecological conditions, select different ecological types of high yield and quality of new varieties, soybeans to achieve an output of more than 200 kg of indicators, the cultivation of technical specifications Yes:
First, use high-yield new varieties
According to the local ecological conditions, choose the appropriate variety, such as Tiefeng No. 24, which has a large potential for yield increase in the plains, and in the western arid region, lost more than 7009 to compare drought resistance and high yield. At present, the new soybean varieties promoted by our province are: Liaodou No. 1, Tiefeng No. 24, No. 27, and Xin 1 loquat varieties have yield potential of 250-275 kilograms per mu with wide adaptability. They are widely used in mountainous regions, plains, and depressions. Can be grown.
Second, pay attention to, rational fertilization
In order to seize high yields of soybeans, it is necessary to reconcile the flat terrain, have irrigation conditions, have a high content of organic matter, and fertile soil, and put an end to re-emphasizing and cultivating. Emphasizes the addition of high-quality agricultural auxin 2000-2500 kilograms, together with the application of nitrogen, phosphorus, potassium and other fertilizers, generally apply 10-15 kilograms of urea per mu, 10-15 kilograms of diammonium phosphate, 10-12 kilograms of potassium sulfate, and agricultural fertilizer. Phosphorus and potassium fertilizers were used as base fertilizers in early spring soil preparations and when they were planted. Nitrogen fertilizers were applied before flowering or at early flowering stages. Soybean special fertilizer can also be used for seed dressing. The seed is used for seed dressing of 0.5 kg of soybean special fertilizer per acre. When the fertilizer is applied, the fertilizer is diluted with water and then reduced, and then it is poured on the seeds, so that the seeds are affixed with fertilizer. sowing.
Third, the fine sowing, reasonable to leave seedlings
Using isometric hand-sweep sowing or mechanical isometric on-demand, Mubaobao 10,000 strains are left in different varieties. Density is also different, such as Tiefeng No. 27 Mu seedling 0.8-1.0 million Zhu, Xindou No. 1 Mu seedlings 1.1-1.3 million. Seeds should be selected, the purity is higher than 98%, and the sowing volume is about 3.5% kilograms.
In early May sowing, so that the soybean flowering season is facing the rainy season, is conducive to the development of soybean meal. Generally, the ridge distance is 53 centimeters, the distance between holes is 10 centimeters, and the number of acres of seedlings is 11.45 million. Using the method of ploughing and sowing seedlings, we have 2 seeds, about 3 centimeters of cover soil, and the depth is uniform. After the sowing, we can suppress the seedlings in a timely manner.
Fourth, advance exploration, strengthen management
About 7 days of planting, the seed has just been set to shovel the dream students, squatting upwind, warm soil, and promote seedlings early hair. The young seedlings grow to two true leaves with a compound leaf. When the seedlings leave a single seed per hole, the seedlings are used for the seedlings to create good nutrition and environmental conditions for the growth of the individual plants, which play the role of seedlings and control of legacies. In the late period of branching, ensure that three shovels and four picks are used, one large grass is allocated, and the soil is loose and there is no weed.
During the period of grain filling, water should be supplied, and the plough layer must reach 40% or more. In the event of drought, watering is required. In the late growth stage, according to the plant growth, 0.5% potassium phosphate solution can be sprayed and 0.5% phosphorus can be released to promote Hi particles increase grain weight and prevent lodging to promote precociousness.
V. Timely prevention of pests and diseases
In the end of June, 800 times of Dongguo was sprayed to control aphids.
In mid-July, Phosphate poisonous soil was applied to control aphids and spider mites, 2 kg per mu, and 15 kg of fine sand.
In mid-August, it was used to prepare a “sustained release card†with diterpene or dimethoate as a “sustained release card†to control soybean borer and ensure soybean yield and quality.
