Sowing the autumn zucchini in early August can be used to cultivate the zucchini seedlings under the cover of shade nets or insect nets. The key to the cultivation of this zucchini is to prevent the occurrence of viral diseases, especially the seedling period of more than 20 days after sowing is a critical period for disease prevention. First of all, the nursery soil should be taken from the disease-free field; secondly, the seedling stage can not be drought-deficient or water-storing; thirdly, to prevent the mites, it is best to cover the seedlings with insect-proof nets. The harvest of this zucchini is from the end of September to October.
The cabbage planted with Chinese cabbage in winter storage has strict requirements on temperature during autumn sowing. Generally, it is sown before and after “Liuqiuâ€. It is easy to be sick early, and the late sowing is short, and the cabbage is not tight. Cabbage should be planted in high ridges.
The early spinach spinach is cold and cool, and it is difficult to sow because of the high temperature. Therefore, the seeds should be soaked for 15 hours before sowing, and then spread on the shade, covered with a damp cloth for germination. The soaked seeds can also be placed in a damp cloth bag, and then hanged in a refrigerator freezer for low temperature germination, shaking once a day, and then some seeds can be sown after germination. After the germination, the seeds should be wet, that is, after the sputum is done, the water is sown and then spread, and then the soil is covered. Germination and sowing in cold conditions can make spinach emerge quickly, so that it will be available at the end of September.
After sowing in the autumn, the cucumbers are usually planted in the early August, planted on high ridges, planted in 2 rows per ridge, and the seeds are germinated before sowing, and 3,500 seedlings per acre are kept. It is also possible to use nutrient mash to concentrate seedlings, and the seedlings grow to the 3 leaf stage and then planted according to the required plant spacing. This cucumber began to harvest at the end of September, and was shackled in mid-October. It was pulled in mid-November. If it was covered in multiple layers, the harvesting period could last until the end of November.
Tomatoes and peppers were planted in late August after planting in late autumn. Tomatoes planted 3,600 plants per acre, leaving 3 spikes of fruit topping; peppers planted 5000-6000 plants per acre. After the autumn delay, if the tomato is covered with double layers in winter, the harvest period can last until the middle and late November; when the pepper is planted, if the small arch shed is covered in the greenhouse and the grass hoe is covered, the harvesting period can last until late December.
Planting wintering vegetable wall thickness of 1.5 meters or more, good heat preservation greenhouse should be planted in the late August, warm fruits and vegetables. The density should not be too large, the tomato should not grow more than 3000 plants per acre, the eggplant cultivation density is 3200-3300 plants/mu, and the peppers plant more than 4,000 plants per acre.
The above vegetables can be mixed with new high-fat membrane before sowing, which can keep warm, moisturize and swell, improve the germination rate of seeds, make the seedlings strong, repel the underground pests, isolate the virus infection, and mix with the seed coating agent. After sowing, the new high-fat film 600 spray can be used in time to automatically form a polymer protective film that is invisible to the naked eye to optimize the water absorption, breathability and light transmission quality of the plant. Blocking pests and smuggling signals and weakening the media to resist and defend against natural environmental disasters.
