Vegetable Farming Guide for the Spring Festival

1, spring greenhouse vegetable management

Spring sheds are vegetables that are harvested from March to early July. Most of the melon vegetables enter the vegetative period after the beginning of spring, and the vegetative growth and fruiting results of the eggplant vegetables are also at the same time. Do the following cultivation and management work:

(1) Insulation and antifreeze. There are two causes of cold damage and cold injury in early spring: First, the vigorous growth of plants, coupled with the increase of water and fertilizer in human management, significantly reduce the cold resistance of plants. After the beginning of spring, there is still a large cold current, which causes cold and cold damage to the eggplant vegetables in the greenhouse. To this end, we must continue to do a good job of preventing freezing and freezing. Solanaceous vegetables already have a large amount of growth and must be covered in two membranes in a greenhouse. The melons are more susceptible to freezing than the solanaceous fruits. In addition to the use of two-film covering, the rice straw bundles can be stacked around the skirt film outside the greenhouse to enhance the penetration of cold air around the greenhouse; the melon seedlings still in the nursery stage, at night Sunshade nets, straw curtains or non-woven fabrics can be covered in small arches to enhance the heat preservation capacity; in the event of strong cold air coming, measures must be taken to prevent freezing and heat preservation.

(2) Ventilate well. After the beginning of spring, with the increase of sunshine time, the temperature rises and the humidity in the shed increases. To reduce the occurrence of pests and diseases and meet the environmental conditions for the growth and development of melons, the management of temperature and humidity in the shed must be done carefully, depending on the weather and plant growth. Status, do a good job in opening and removing film ventilation, closing and cover film insulation management.

(3) Do a good job of flower protection and fruit preservation. Low temperatures will affect the fertilization results of more varieties of vegetables, and they are prone to falling. At present, the method of improving fruiting is to apply a plant growth regulator to the ovary or to apply the plant growth regulator in accordance with the instructions, so as to prevent the concentration from being too high and the phytotoxicity to occur. The second is artificially assisted pollination.

(4) Do pest control work well. 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. Pest control should be combined with agricultural control and chemical control, such as good management of temperature and humidity in the shed, reduction of humidity in the shed, grassing in trenches, rational water fertilization, timely pruning, removal of old leaves, spraying of pesticides for prevention, etc. .

2, spring greenhouse vegetable seedlings

Melon seeds are sowed in electrothermal hotbeds before and after the beginning of spring. They are selected for early maturation, high yield, small development, short internodes, suitable for dense scaffolding, early emergence of female flowers, easy fruit setting, low temperature and low light resistance, moisture resistance, and resistance. Excellent varieties with strong disease characteristics.

3, greenhouse fruit and vegetable colonization

(1) Solanum fruit. As early as tomato cultivation, can be planted after the beginning of spring.

(2) melons. After Yu Lichun, they were planted in small plastic sheds or covered with plastic sheds in small sheds.

4, open vegetable cultivation and management

(1) Mainly do a good job of fertilizing, draining water after the rain, and racking up the beans. Mature vegetables are harvested in time.

(2) For the cultivation and cultivation of cruciferous vegetables (such as Chinese cabbage, vegetables, and radish, etc.), topdressing and field miscellaneous work must be done to ensure seed purity and quality.
