Core Tip: Temperatures have continued to rise in recent days, with abundant sunshine, increased rainfall, and high temperatures. Most of the fruits and vegetables in the greenhouse are in the pull period, and some of the heat-resistant varieties of open-field vegetables enter the harvest period. This period is also the critical period for the autumn cauliflower, cabbage and tomato, pepper and eggplant nursery in the autumn, carrot, Precooked Chinese cabbage and open-cucumber planting period. At present, it is necessary to do a good job in harvesting, seedling raising and sowing under the hot summer heat to ensure the increase in production and income in the whole year. A. Cauliflower, Cabbage, Indigo, Lettuce and other crops grown in the open field in autumn The nursery was selected from the end of July to the beginning of August. Cucumber in open field is selected from heat-resistant, early-maturing and disease-resistant varieties, sowed in the middle and early July, and supplied in the off-season market from late August to early October. To apply enough organic fertilizer to make ridges and ridges, you can't lay the mulch and plant them at a density of 70 to 75 centimeters and 30 to 33 centimeters. B. Peppers, sweet peppers, and colored sweet peppers grown in the greenhouse in autumn To raise seedlings in late July, the greenhouse with poor insulation performance should be cultivated for 5 to 10 days. The color bell pepper should be properly reared and the seeding period should be in mid-July; the general seedling age should be 45 to 50 days, and it should be planted from late August to early September. From the beginning of November to the Spring Festival, the market is harvested. In greenhouses with good ventilation and low temperature, 50-hole plastic plug trays are used, and special substrates for raising seedlings or peat, vermiculite, and perlite are used as substrates. Do warm soaking and soaking seed germination, germination at 25 °C ~ 30 °C environment 6 ~ 7 days until the seed germination when sowing. C, autumn and winter greenhouse tomato Generally in the middle and late July seedlings, planting in mid-August, harvesting from mid-November to mid-January; greenhouses with poor insulation properties should be properly nursed. In recent years, tomato yellow leaf curl virus disease has been seriously affected. Once the infection occurs, it often results in a significant reduction in production, or even no harvest. The best prevention method is to start from the seedling stage, use shade nets, shed film rain, insect nets and other "full protection" measures to nurture strong seedlings to prevent the spread of poisoning by the whitefly. D, autumn greenhouse cucumber Planting in late July; Cucumber selection of early-maturing, disease-resistant, good quality "Zhongnong 16" and other varieties, nursery in mid-July, planting in early August, using 72-hole plastic plug seedlings, to peat and vermiculite, perlite For the substrate; cucumbers can also be sowed directly in late July. E. Autumn greenhouse celery Planting in mid-September, the seeds must be sown after low temperature germination. After soaking for 24 hours, sow the seeds by hand to remove the germinating substances on the seed coat, and then place the germination at 17°C～20°C. In 6 to 7 days, germination can be done in a place 50 cm above the surface of the well. Wait until the seeds begin to sprout, and do a good job of protecting the seedling sheds. F, early-maturing cabbage The early-maturing and heat-resistant varieties such as “Xiaoza 56†and “Betty†were selected and harvested before and after the National Day and Mid-Autumn Festival. It is necessary to apply basic fertilizers, fine soil preparation, watering and cooling in the rows after sowing, and to prevent diseases such as virus diseases, aphids and cabbage caterpillars from the seedling stage. G, autumn wolfberry carrots In the middle and late July, sowing is started. The roots are beautiful, high-quality, high-yield varieties such as “red core 228†with red, peel, pulp, and fruit cores. Apply roasted, finely chopped high-quality organic fertilizer 4000 kg or commodity organic fertilizer 3000 kg per acre. After intensive cultivation, make sorghum seeds and sow seeds evenly. Use about 300 grams per acre.
