At present, the summer soybean is in the seedling stage, and the management of the seedling stage should be "three early", in order to achieve the goal of uniform seedlings, strong seedlings, and no pests and diseases.
Check seedlings for replanting early
The lack of seedlings and ridges, and the unevenness of seedlings, will not only cause loss of light leakage, but also the phenomenon of big seedlings bullying small seedlings. If the lack of seedlings exceeds 30 cm, it may be replanted or replanted. Before replanting, the seeds can be immersed in water for 2 to 3 hours. When transplanting seedlings, they should be transplanted with soil and selected on cloudy days or after 4 pm, and watered immediately after transplanting.
According to the experiment, the fixed-term seedlings can increase yield by about 8% to 17% than the late-term seedlings. If there is no insect pests or rabbits eating, the seedlings should be early and not late. Generally, the soybean seedlings can be carried out after the seedlings are removed, and the time to remove the pimple seedlings, weak seedlings, diseased seedlings, small seedlings, can avoid the appearance of linear seedlings, high-footed seedlings, etc. Lodging seedlings appear. Seedlings can be fixed at the time of 1 to 2 compound leaves, and about 10,000 to 15,000 seedlings can be retained per mu depending on the variety and fertility.
Early weeding, prevention of diseases and insect pests
First, weed control must grasp the principles of small and early control. Summer soybean crops grow faster and weeds grow faster, and grass shortages can occur if you are careless. Therefore, we must master the principles of small and early control for weed control.
At present, most soybeans have emerged and can be removed from stems and leaves. Fields with stubble planting and single and double dicotyledonous weeds, in the soybean 2 to 3 compound leaf period, use 5% fine grass for each acre 75g + 25% Huwei 60 to 70ml, add 15kg of water and spray evenly , Can control most broad-leaved weeds and gramineous weeds.
The second is to prevent diseases and insect pests as early as possible to protect seedlings and strengthen seedlings. The timely prevention and control of diseases and insect pests at the seedling stage can not only protect seedlings and strengthen seedlings, but also effectively prevent the disease.
Insect pests at the seedling stage of soybean mainly include sting-sucking pests such as aphids, thrips, planthoppers, and whiteflies, and leaf-eating pests such as beet armyworm, cotton bollworm, and scarab. There are also many snails when there is a lot of rain. 10% imidacloprid wettable powder 40-70 g/mu can be used to control aphids and other sucking pests; Kang Kuan (20% chlorantraniliprole) can be used to control leaf-eating pests such as beet armyworm and cotton bollworm. ～10ml/mu for prevention and control; for both sucking and sucking pests and leaf-eating pests, 5g/mu of Fogo (20% chlorantraniliprole + 20% thiamethoxam) can be used.
Early control to cultivate strong seedlings
The criteria for strong seedlings are: developed root system, more lateral roots, more nodules; more branches, thick young stems, short internodes, the length of the internodes from cotyledons to opposite leaves should not exceed 3 cm; cotyledons and leaves are thick, leaves are not missing, leaves True color. If it is not particularly dry at seedling stage, it is generally not watered, and it should be drained in time when there is too much rain.
Soybeans sown in stubble can be cultivated when there are 1 to 2 true leaves of soybeans. The first cultivator should be deep cultivating, with the purpose of loosening soil, loosening soil, stubble weeding, and at the same time, it is necessary to prevent seedlings from carrying soil. The depth of the second mid-cultivation should be determined by the conditions of the seedlings. The vigorous seedlings can be controlled by deep cultivation. For the non-mature seedlings, it is not necessary to be too deep. The purpose is to loosen the soil and protect the soil moisture. The third cultivator should be shallow, and can be combined with soil cultivation for the purpose of loosening soil, weeding, and preventing lodging. Before soybeans bloom, they should stop plowing. Fields where bean seedlings are prosperous can be combined with spraying, and 5 grams of 15% paclobutrazol can be sprayed on water per mu.
