Vegetable field management in the spring

First, nurture strong seedlings

Greenhouse vegetables are dominated by solanaceous fruit and melons. Cultivating strong seedlings is the key to achieving high quality and high yield of vegetables. Doing a good job in field management at the seedling stage is mainly to maintain temperature, control humidity, and prevent and control diseases.

1, temperature control: daytime temperature control at 20 °C -25 °C, night 10 °C -15 °C. If the temperature is too low, the coverage must be strengthened. During the day, the temperature must be too high.

2. Humidity control: The humidity in the booth should be controlled at 60-70%. If the humidity is too high, it is necessary to do a good job of ventilation and humidity dewatering. If the humidity is too low, watering should be timely.

3, control pests

After entering March, cucumber will develop downy mildew, anthrax, epidemics, gray mold, etc. Tomatoes may develop gray mold, leaf mold, early blight, late blight, spot blight, and gray mold in zucchini. Powdery mildew and other diseases such as eggplant and pepper can occur. These diseases are all fungal diseases. In addition to strengthening the ventilation and reducing the humidity during the prevention and treatment, carbendazim, chlorothalonil, frost-emulsion, and glucide can be used for prevention and treatment. Insect pests are mainly aphids and whiteflies. They should be installed in the vents of greenhouses and greenhouses, and then be confined and sealed with dichlorvos, anti-virals, and can be sprayed and sprayed with LS.

Second, make preparations before planting.

In order to make vegetable seedlings robust and able to adapt to a low-temperature environment after planting, exercise should be performed for a period of time (about 10 days) before planting. Strengthen ventilation, reduce greenhouse temperature, reduce watering, and control growth. Low-temperature exercise is an effective measure to prevent leggy and frost damage, and it has the effect of promoting flower bud differentiation and early flowering and fruiting.

Third, colonization and seedling management.

Tomatoes, cucumbers, peppers, eggplants, and other seedlings cultivated in large and medium sheds should be planted in greenhouses and middle sheds one after another in mid to late March. If multiple layers can be covered after planting, it will not only shorten the period of seedling but also prevent the damage caused by weather mutations. Carefully grasp the following questions when planting:

1. Apply more organic fertilizer and less nitrogen fertilizer. 2500 kg chicken manure per acre. The application of organic fertilizer is much more effective, the plants can grow robustly, and the disease resistance will not only increase, but also the yield of the vegetables is high and the quality is good.

2, the density is appropriate smaller. Appropriate planting not only grows well, the disease is light, and the amount of fertilization is reduced. It also increases the individual's growth space, avoids the occurrence of melon and flowering, and makes the fruit grow large, with good taste and color. Tomato and cucumber acres can be planted 3200 ~ 3500 strains.

3, early planting can promote early-onset seedlings, but the risk is large, so after the planting should be multi-layer coverage, so be prepared.
