The farmer said: "A cold autumn rain." At the end of the solar heat season, the temperature gradually decreased, sunshine was sufficient, and rainfall decreased, which was conducive to the growth of vegetable crops. At this time, it is an important period for the cultivation of vegetable seedlings, planting and management, and it is also a critical period for the management of autumn vegetables in open fields. At the same time, pest and disease prevention and control work must be strengthened. Autumn and winter green house vegetable colonization In autumn and winter, greenhouses, such as tomato, eggplant, and pepper, are suitable for planting in late August to early September. The greenhouses with good insulation performance can be cultivated in winter, but they must be planted later. Pre-filmed the shed film, selected EVA functional film for dripping and fogging, and PO film for conditions; the tomato and eggplant sheds should be replaced with new films; eggplant should not use PVC plastic mulch, otherwise it will affect the fruit. Coloring. The bottom of the next agricultural film is temporarily buried in the soil and sealed with insect nets in order to release the wind. Do a good job of disinfection of greenhouses and soil. The greenhouse can be sterilized by sulphur fumigation, with a dosage of 3 kg per mu, or 4 g per cubic meter of space, and 8 g of sawdust, which is lighted and sealed for 24 hours and then exhausted. Can also be used 45% chlorothalonil smoke agent 200 to 250 grams per mu or 30% fast Ke Ling smoke agent 300 to 500 grams, ignition seal 2 to 3 hours after the release. Apply organic manure as base fertilizer and apply 5000 kg of sufficient quality and organic fertilizer into each acre. If unfainter organic manure is used, it will not only supply nutrients to the crops in time, but also cause roots to affect the growth of crops. Underground pests are harmful. Therefore, organic fertilizers must be thoroughly cooked before they are applied. If the source of organic fertilizer is insufficient, bio-organic fertilizer or commodity organic fertilizer can be applied, with a dosage of 3,000 kg per mu. For fine soil preparation, ten to fifteen days' advance fertilization of cultivated land should be done so as to plough through and level the soil without making any light or darkness. The sorghum or ridges raised 15 to 20 cm above the ground should be used, and the ridges and ridges should be suitable for sheds without drip irrigation facilities. Dig a V-shaped watering ditch in the middle of the raft to facilitate watering under the membrane in winter. Planting in the end of August should be planted first, and then after the cultivator is covered with mulch, the colonization after the beginning of September should be covered with mulching and then colonization. Pay attention to the quality of colonization. The selection of strong and uniform seedlings of the same size and size requires a suitable depth and density. The average common tomato variety is about 3,000 per acre, and the cherry tomato variety is 2200, and 2 to 4 plants per pod are used to make up the seedlings. Greenhouse Vegetable Management Tomatoes, cucumbers, and other crops grown in the autumn greenhouse are at the fruiting stage; the plants in summer such as loofah, bitter gourd, pepper, and eggplant are also in the flowering period. At this time, the weather gradually becomes cooler, which is favorable for flowering pollination and fruit enlargement. It should be strengthened. Field management promotes fruit with high rates of multi-knot crops. The first is to adjust the appropriate temperature, light and humidity in the management measures; the second is to prune in time and around the vines; the third is to promote fruit set, the tomato can adopt bumblebee-assisted pollination or pollinator-assisted pollination to increase the fruit setting rate. Eggplant in the greenhouse when the temperature is too high should not sit on the fruit, the use of good safety "Fengcengji No. 2" spray flowers or flowers; the fourth is scientific watering, top dressing, in the vegetative growth control of water and fertilizer, promote plant root system Stretching downwards, control overgrown stems and leaves. When the first panicle grows to 3 cm in size, it will be top-dressed with water and the cucumber will be top-dressed when the young grows. The fifth step is to strengthen pest control, especially to prevent the occurrence of tomato yellow leaf curl virus. Sealed with a 50-mesh insect net to timely control the damage of the whitefly. Qiu Lu exposed vegetable management The cauliflower, cabbage, lettuce and other crops planted in open fields are in the stage of rosette. It is the stage of growing the outer leaves of the tree. The first step is to cultivate loose soil and “seedlings†to promote root growth and avoid excessive leaf growth. If 3-5 days after cultivating, the rain should be cultivated to facilitate the growth of roots. The “seedlings†period is generally about 15 days; the second one is watering topdressing. After the end of the "seedlings", watering and topdressing were started. After the opening of the acre, 15 kg of Sanyuan compound fertilizer was applied. The third was to control pests such as aphids and Brassica napus in time. Biocides such as Bacillus thuringiensis and low-level, low-residue pesticides should be used to control at night.
