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.
1. Seed Chinese cabbage. The winter storage of cabbage in the autumn sowing is very strict with the temperature requirements, generally before and after the "Early Autumn" sowing, early broadcast susceptible to disease, late sowing growth period is short, cabbage is not tight. Cabbage should be planted on high ridges.
2. Kind of early spinach. The spinach is fond of cold, before and after the autumn, due to high temperature and difficulty in germination, the seeds should be soaked for 15 hours before sowing, and then spread on the shade at the top, covered with a damp cloth for germination. The soaked seeds can also be placed in a damp cloth bag, then suspended in a refrigerator freezer for low temperature germination, shake once a day, until some seeds start to germinate after sowing. After the germination, the seeds should be sowed wet, that is, they should be sowed and then covered with soil after they have been ploughed. Sprouting under cold conditions can make spinach sprout quickly so that it can be marketed by the end of September.
3. Sow the cucumber after the fall. After the fall of greenhouses, cucumbers are usually planted in early August and planted on high ridges. Two rows per ridge are planted. Seeds are germinated before sowing and 3500 strains per mu are maintained. 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.
4. Plant tomato and pepper after autumn extension. Planting tomato and pepper seedlings in late August. Tomato 3600 per acre seedlings, leaving 3 ear fruit topping; pepper per acre seedlings 5000 to 6000 strains. 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.
5. Planting winter vegetables. The greenhouse with a wall thickness of 1.5 meters or more and good heat preservation should be planted with thermophilic fruit and vegetable vegetables in late August. Density should not be too large, tomato seedlings per acre does not exceed 3,000, eggplant cultivation density of 3200 ~ 3300 / acre, pepper planting more than 4000 strains per acre.
6. Sown autumn zucchini. In early August, the squash seedlings can be cultivated under the shade nets or insect nets with nutrition. The key to the cultivation of this zucchini is to prevent the occurrence of viral diseases, especially the breeding period of more than 20 days after sowing is the critical period for disease prevention. First of all, the nursery soil should be taken from the disease-free field; Second, the seedling stage can not be drought or water shortage or flooding; third, to prevent locusts, it is best to use insect nets to cover the nursery. The harvest of zucchini is from the end of September to October.
7. Seeding autumn leaves vegetables. In late August, some leafy vegetables such as cabbage, oiled wheat, coriander, and fennel can be broadcast. After the emergence of these vegetables, it is the cool autumn weather, suitable for growth requirements.
