The high temperature in September has passed and the weather has turned cold. Vegetable production has entered a busy season.

First, sowing, nursery

1, greenhouse vegetables. In September and October, greenhouse eggplant, tomato, and pepper are planted and cultivated in Winter. The temperature is high, rainfall is high, seedlings grow quickly, seedlings grow quickly, but it is prone to leggy. In order to cultivate homogeneous and strong seedlings, plastic greenhouse facilities should be used as much as possible for ventilation, cooling and sheltering. When the seedlings grow to 2 leaves and 1 heart, they are transplanted in time.

2, exposed vegetables. Autumn vegetables, autumn celery, autumn potatoes, radishes, spinach, garland chrysanthemum, stem lettuce, etc. sown seedlings or sowing in batches this month. Must choose the appropriate species, pay close attention to soil preparation, good quality. Lettuce and celery are planted from late September to mid-October; green garlic (seedlings) is planted in August until early September; onions are planted in the middle of this month. In addition, fast-growing vegetables, such as young vegetables and spinach, can be sown in batches in batches to ensure the supply of off-season vegetable markets.

Second, planting

Can continue to carry cauliflower, broccoli, cabbage, early autumn celery and other colonization, generally required to be planted in early this month; Autumn lettuce sown in mid-August, can be planted in the middle and late of this month, with mulching cultivation. For the colonization of vegetables, the appropriate plots should be selected, and the appropriate row spacing should be determined according to the characteristics of different crops. Transplanting should be carried out on cloudy days or after 3:00 pm, and water should be poured into the roots. When necessary, use shade nets to cover 2-3 days to ensure survival and improve the quality of colonization.

Third, field management

In the fall of this month, vegetables will enter the period of vigorous growth of vegetative growth and the fruiting period of flowering. We must do a good job of cultivation management.

1, greenhouse vegetables. The key points of field management are: (1) Ventilation is to reduce the temperature and avoid rain. The temperature is still high in the middle and early middle seasons. The greenhouses should be rolled up around the skirt film to cool down the ventilation and cover the film before heavy storms. (2) Strengthen the management of fertilizers and waters. High temperatures in greenhouses and strong production of melons must be supplemented with fertilizers and water in a timely manner to keep the soil moist. Where possible, drip irrigation is used. (3) To protect the flowers, use plant growth regulators to protect the flowers, reduce the use of the appropriate concentration, after 4 pm to spend.

2, exposed sweet potatoes vegetables. Vegetables in open field should be cultivated and managed in accordance with the technical requirements for the production of non-polluted vegetables according to the growing period of different vegetables. Such as cultivator weeding, scaffolding and introduction of vines, timely pruning, removal of old (yellow) leaf disease leaves, reasonable fertilizer, timely drainage after the rain. Early maturing cauliflower, early autumn cabbage, and early-maturing Chinese cabbage, etc., must be cultivated, weeded and thin-fertilized in a timely manner, and the prevention and control of pests and diseases should be carried out. The growth potential of autumn soybeans should be combined with the application of phosphorus and potash fertilizers, and nitrogen fertilizer should be supplemented properly. The application of potassium dihydrogen phosphate and borax should be performed outside the roots to increase the fullness of the fruit.

Fourth, harvest

The vegetables that can be harvested this month are: small green vegetables, autumn kidney beans, autumn beans, radish, white peony, wax gourd, gourd, etc., which need to be harvested in time, and are abundant in the supply of off-season vegetable market.

V. Pest Control

In September, the cruciferous crop was dominated by vegetable crops. The main insect pests were Spodoptera litura, Spodoptera exigua, Plutella xylostella, and Pieris rapae. Can be used to dilute, dish hi, anti-Taibao Jiamiman, farm music, etc. to be controlled. The main diseases are cauliflower black spot, Chinese cabbage, white cabbage leukoplakia, etc. It can be controlled by agents such as zein zinc, chlorothalonil, or Xinwansheng. Cabbage black rot and Chinese cabbage soft rot can be controlled by agricultural streptomycin. Soybeans and other seedlings are mainly used for the prevention of damping-off disease. Except for seed dressing, they can be regularly treated with thiophanate-methyl or chlorothalonil, and cowpea should be taken care of for prevention and control of soybean pods, spider mites, aphids, and Liriomyza sativae. Etc., etc.; focus on the prevention and control of locusts. The use of pesticides should be strictly in accordance with the relevant requirements for the production of pollution-free vegetables. In addition to the prohibition of the use of high-toxicity and high-residue pesticides, the safety interval of various pesticides must be strictly controlled before harvesting.
