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 crucial 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 properties 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 conditional use; the greenhouses for tomatoes and eggplants should be replaced with new ones; do not use PVC plastic film for aubergines, otherwise the fruit will be affected. 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, 8 g of sawdust, and after 24 hours of lighting and sealing, the air is discharged and 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 unfamiliar 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, fertilize the cultivated land 10 to 15 days in advance so that it can be cultivated, leveled, and free from obscurity and filth. The sorghum or ridge ridges 15 to 20 cm above the ground should be made, 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. After the cultivating, the mulching film should be covered. After the beginning of September, planting should cover the mulch before planting.
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 are planted in each plant to prepare for seedling replacement.
Greenhouse Vegetable Management
Tomatoes, cucumbers, and other crops grown in the autumn greenhouse are at the flowering stage; the plants in summer such as loofah, bitter gourd, pepper, and eggplant are also in the flowering period. The weather gradually cools, which is conducive to flowering pollination and fruit enlargement. It should be strengthened. Field management promotes fruit with a high rate of multi-foliage products. 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 larvae start to elongate. Fifth, pest and disease control should be strengthened, especially to prevent the occurrence of tomato yellow leaf curl virus. Sealed with a 50-mesh insect net to timely control the damage of 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 top dressing. After the “seedlings†are finished, they start watering and topdressing. Each acre has a hole and topdressing 15 kg of Sanyuan compound fertilizer. The third is to prevent and control pests such as aphids and cabbage beetles in time. Biocides such as Bacillus thuringiensis and high-efficiency, low- and low-residue pesticides should be used to control at night.
