February vegetable production and management
In February, the temperature was low, the sunshine was least, and there was frost damage. Vegetable production should attach great importance to the cultivation and management of insulation, antifreeze and cold damage.
First, the spring greenhouse vegetable management
1, thermal insulation. Improve the greenhouse insulation performance, strengthen the insulation management; appropriate sowing, plant training; spring water and fertilizer should be gradually increased, can not be rushed. In addition, potassium dihydrogen phosphate and rare earth micro-fertilizers were sprayed on the leaves of vegetables and other crops in greenhouses in time.
2, good ventilation ventilation. In February, the temperature rose and the moisture in the shed increased, which was prone to high humidity and low temperature diseases. Therefore, the shed temperature and humidity management work must be done carefully, and the management of door opening and membrane ventilation, door closing and cover film insulation should be well done depending on the weather changes and plant growth conditions.
3, do a good job of flower protection and fruit preservation. Plant growth regulators were used to dip or apply to the ovary. Solanaceous vegetable varieties were often covered with anti-decantin. The use of plant growth regulators should be used according to the instructions to prevent excessive concentrations and phytotoxicity.
4, do pest control work. In February, as the temperature rises and the humidity in the greenhouse increases, the vegetables in the greenhouse are susceptible to gray mold, disease, blight, and aphid damage. Pest control should be combined with agricultural control and chemical control, such as the management of temperature and humidity in the shed, reduction of humidity in the shed, grassing in trenches, rational fertilization, timely pruning, removal of disease, old leaves, spraying of pesticides for prevention, etc. .
Second, the spring greenhouse vegetable seedlings
The use of plastic greenhouses for melon cultivation, in February is the growing season of more melon varieties. For example, silty squash, cucumber, gourd and other seedlings are planted in early February. The sowing time for cultivation of dwarf bean greenhouses is generally from mid-February to late. In early spring, leafy vegetables such as spinach, leeks, garland chrysanthemum, alfalfa, celery, etc. can generally begin sowing in the late. Others such as spring cabbage, spring cabbage, spring radish, etc. can be used greenhouses and small arch shed seedlings. For the cultivation of vegetables in spring greenhouses, sowing of seedlings in February, the best use of electric hotbed nursery, seed disinfection before sowing and soaking germination to ensure Miao Qi, Miao whole, Miao Zhuang.
Third, open cultivation and management of vegetables
The main varieties of vegetables that grow in open field in February are green vegetables, cabbage, cauliflower, peas and other varieties. The main tasks include fertilization, drainage after rain, and racking of beans. Mature vegetables, such as red cabbage, Chinese cabbage, Chinese cabbage, cauliflower, cabbage, late-maturing radish, garlic, celery, spinach, Chinese wolfberry, and garland chrysanthemum have to be harvested in time. Brassica oleracea, late spring lettuce and spring cauliflower, can be planted one after another, covered with mulching; radish sowing in the middle and late of this month, the selection of short growing period, strong cold resistance, strict vernalization requirements, late bolting, not easy to hollow cultivation, such as Bai Yuchun radish and Chunbai No. 2 can be introduced into the test.
