Farming in vegetable fields in the August transition period

August is a transitional period from summer to autumn, with higher temperatures in the first half of the month and slightly lower temperatures in the second half of the month. Rainwater is also declining. It is imperative for the vegetable production to be early and late, and to do a good job in autumn sowing. Storage of cabbage and radish in winter is very strict with the temperature requirements in autumn sowing, generally should be sown in late August, early broadcast susceptible to disease, late sowing growth period is short, cabbage is not tight, radishes grow small. Early spinach likes hot and cold, before and after sowing, due to high temperature and germination difficulties, so the seeds should be soaked for 15 hours before sowing, and then spread to the shade, covered with a damp cloth to germination. The soaked seeds can also be placed in a damp cloth bag, and then suspended in the well at a distance of 1 m from the water surface for germination at low temperature. The shaking is performed once a day until some of the seeds begin to germinate. The germinated seeds should be sowed. Sprouting under cold conditions can make spinach sprout quickly so that it can be marketed by the end of September. The varieties can be selected for their leaf thickness, color depth, and heat-resistance varieties. They should be sowed when planted. The amount per mu is 750 grams. After the fall of the cucumber greenhouse, the cucumbers are usually planted in early August. The varieties can be selected from Jinlu No.1 and Jinlv No.4. They can be planted on high ridges, with 2 rows per ridge, and the seeds can be germinated before sowing. 3500 seedlings per mu. It is also possible to use nutrient pods to raise seedlings. Seedlings grow to the 3-leaf stage and are then planted at the required spacing. The cucumbers will be harvested at the end of September and will be shed in mid-October, and will be pulled in mid-November. If multiple layers are covered, the harvest period will last until the end of November. Cultivated autumn and winter cucumbers are generally sown in late August, and they are harvested in mid-to late October. The harvest period can be continued until the beginning of January of the following year. After harvesting, the winter and spring vegetables are planted. Autumn potato sowing is in early August. Before sowing, individual sweet potatoes weighing about 30 grams can be selected and germinated in the house with wet sand. It can also be cut like a potato sown in spring. The wounded surface should be washed with clean water and allowed to air for 2 hours. Then, the soil should be buried in sandy soil with a moisture content of 3% to 4% and covered with a thin film to prevent sand from drying out. Water loss, when the buds have a length of 1 cm, the potatoes are picked out and scattered under the scattered light, and the sprouts continue to germinate. If the sand is dry, the amount of water can be sprayed. When the buds are basically out of the line, they are stepped on the field at a 60 cm line spacing, and the shallow ditch is opened according to the line, and then placed at a spacing of 20 cm, and then the soil is sealed off from both sides to seal the high ridge. After the planting of autumn, tomatoes, peppers, tomatoes and pepper seedlings cultivated under shade nets and insect nets in the middle and late July will be planted after the high temperature weather in late August has passed. Tomato 3600 per acre seedlings, leaving 3 taro fruit topping; pepper 5000-6000 per acre planted seedlings, each planting 5 rows to leave 80 cm wide space as a small arch shed in the winter walkway. After the fall, if tomatoes are covered in double layers in winter, the harvest period can last until mid-to-late November; when planting pepper, small greenhouses can be covered with straw sheds and the harvest period can last until late December. Planting winter vegetables in the greenhouse should be planted in the warm vegetables and vegetables in late August. Due to the long winter season, the density should not be too large. Tomato seedlings per acre does not exceed 3,000, eggplant cultivation density is 3200 to 3300 plants/mu, and pepper plants more than 4,000 plants per acre. Winter fruits and vegetables will enter the peak harvest period in autumn and winter, and will enter the harvest peak in the next spring. Autumn zucchini can be used in early August to cultivate squash seedlings under shade nets or insect nets. The key to cultivation is to prevent the occurrence of viral diseases, especially the breeding period of more than 20 days after sowing. First of all, the nursery soil should be taken from Daejeon. Secondly, the seedling stage should not be arid or water-deprived or the water should be trapped. Third, to prevent locusts, it is best to cover insect nursery nets with insect-proof nets. The harvest of zucchini is from the end of September to October. Autumn leaf vegetable vegetables can be broadcast in late August some leafy vegetables, such as cabbage, oiled wheat, parsley, fennel and so on. After the emergence of these vegetables, it is the cool autumn weather, suitable for growth requirements. Diseases and pests control radish, cabbage dish worms (salmon heartworms, borers) adults love to lay eggs in the heart of 2 to 3 true seedlings, so cabbage, radish should be promptly controlled after emergence. Diseases include cucumber downy mildew, anthracnose, eggplant verticillium wilt, cotton rot, brown vine disease, tomato early blight, cotton rot, virus disease, pepper disease, virus disease, summer radish, summer cabbage, Cabbage, cauliflower virus disease, soft rot, black rot, kidney rust, kidney beans, anthracnose, etc., these diseases can refer to relevant information timely prevention and treatment.
