In recent years, with the acceleration of the process of urbanization in the suburbs of Nanjing, the area of ​​vegetable fields has decreased year by year. In order to improve the land use efficiency of limited vegetable plots, the author conducted demonstrations and promotion of a number of efficient cultivation modes. The current production patterns of Chinese kale, oil and vegetable, Chinese cabbage, and parsley with higher economic benefits are summarized below.
Mouthwash arrangements and benefits
The first crop is kale, with early maturing varieties, sowing seedlings in early April, planting in mid-May, harvesting in late June, yielding 2,000 kilograms per mu, and an output value of 8,000 yuan per mu. The second crop was oil and wheat, which was planted in late May (low temperature germination required), planted in late June, and harvested in late July. The yield was 1,500 kg per mu, and the per mu output value was 6,000 yuan. The third is the vegetable heart, the selection of Guangdong 49 varieties of cabbage, sowing seedlings in early July, planting in early August, harvested in mid-September, 1000 kg per mu yield, production value of about 2,500 yuan. The fourth crop was parsley, which was sown in late July (low temperature germination required) and planted in late September. Harvested from early November to the following May, the yield per mu was 1600 kg, and the yield per mu was about 8,000 yuan.
This model requires high soil fertility and is suitable for areas with fertile soil. Protected cultivation in the year, cold insulation in winter, high temperature and heavy rain in summer and autumn, oil and vegetable, cabbage, and parsley cover the nursery with shade nets. After each harvest, the pastoral gardens were cleaned in time and sunk for 1 week depending on the weather conditions.
Field management
Fertilizer management (1) kale. Apply enough base fertilizer to produce 1,000 kg of organic fertilizer and 50-80 kg of compound fertilizer per mu. Fertilizer after planting to promote the main dry and wet combination. Foliar fertilizer was sprayed for 10 days before harvesting, and water was not collected before harvesting to keep the soil dry. (2) oil wheat dish. Before planting, 800 kg of organic fertilizer and 50 kg of compound fertilizer were used per hectare of the base plant. The soil was kept moist before the living plant. (3) Caixin. The organic fertilizer is 800 kg per mu, and 50-80 kg of compound fertilizer. After the planting and during the growth period, the soil was kept moist, and 1,000 kg of cooked and diluted manure water per acre was applied before budding, and the one-time harvest was completed. (4) Parsley. Slight suppression after sowing, irrigating the water, covering the shade net, and timely removal after emergence. Decomposition of organic fertilizer 1000 kg per hectare before planting, compound fertilizer 50 ~ 60 kg. After planting, the soil was kept moist until harvested, and foliar fertilizer was sprayed before harvest. After each harvest, 10 kg of urea was added to the water and poured.
The main insect pests for controlling pests and diseases include aphids, spotted moths, noctuids, cabbage caterpillars, and diamondback moths, and diseases include downy mildew. Control of aphids can be sprayed with imidacloprid. For the prevention and control of Liriomyza, the avermectin or flufenazil spray should be used as soon as the hazard is first seen. Pest control pests, cabbage caterpillars, and diamondback moth, can be used in the young larvae with farmland music 52.25% chlorpyrifos chlorpyrifos emulsifiable concentrate 1000 to 1500 times, diluting 10% chlorfenapyr suspension 2000 times alternating spray, early evening application The effect of the medicine is best. Artificial larvae should be captured manually. For the prevention of downy mildew, it can be sprayed with 58% Methodyl Manganese Zinc WP 800 times.
