Autumn cucumbers are sown in the middle and late July to early August, and the growth period is high in heat and heat. The seedlings are easy to grow, the female flowers are few, the melons are easy to be used, and the pests and diseases are serious. These points should be made in cultivation management: 1, meticulous care and preservation seedlings First of all, we must pay attention to the selection of varieties with strong heat resistance, such as Jinza No. 2, Jinchun No. 4, and Jinyan No. 7. Secondly, it is advisable to adopt a live broadcast method to overcome the problem of high temperature transplanting. The seeds were immersed in warm water at 55 ° C for 15 minutes, then immersed in water for 3-4 hours, and the holes were opened at a row spacing of 4-5 seeds per hole. Third, after sowing the soil, the ground should be covered with straw to keep the soil temperature down, keep the soil moist, and prevent heavy rain. Fourth, the implementation of large seedlings and seedlings, after the seedlings are unearthed, remove the covered straw, suitable time seedlings 1-2 times, lack of seedlings with 1-2 leaf seedlings with soil replanting. When the seedlings grow 3-4 leaves, they are finally fixed to prevent the seedlings from prematurely due to accidental dead seedlings. 2, scientific fertilization to improve the rate of sitting Autumn cucumber topdressing should be carried out in accordance with the principle of less application. In the seedling stage, under the premise of water control seedlings, appropriate application of quick-acting nitrogen fertilizer and phosphate fertilizer should be applied as early as possible to meet the nutrient requirements of vegetative growth, flower bud differentiation and female flower development. It can be diluted 1-2 times with 8-10 times diluted biogas slurry or clear manure water plus 2% superphosphate. At the same time, after the seedlings of 3-4 leaves of melon seedlings, the plants were sprayed with 0.15% concentration of ethephon solution to promote the early growth and more prosperous female flowers, achieving the purpose of suppressing the seedlings, controlling the length, and improving the early yield. After sitting on the melon, the amount of fertilizer needed to increase, especially the demand for potash fertilizer is greatly increased. Therefore, the number of top dressings and the amount of potassium fertilizer should be increased. Generally, for each 1-2 batches of melon, it is necessary to topdress one time, and the manure water diluted by 3 times can be used. Add 1% potassium fertilizer, and carry out multiple root fertilization, accelerate the expansion of the melon body, and prolong the melon production period. 3, diligent irrigation and flood control Autumn cucumbers often encounter showers and heavy rains in the early stage of growth. It is necessary to pay attention to the prevention of sputum drainage and to prevent the soil from spreading and causing the roots and diseases of the seedlings to spread. The amount of water required for the melon period is high. If it encounters drought, it must be watered to ensure the development of the melon body and prevent the bitterness of the melon meat. Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
