Seven points for vegetable cultivation

First, balanced fertilization. Use open space fertilization to make the soil fat enough; there is a previous crop to fertilizer as early as possible, laying out organic fertilizer, 2000 to 2500 kilograms per acre, and then apply the compound fertilizer, manure water should be uniform, ventilation, insulation. Second, the appropriate depth. Deep-rooted plants such as eggplants and tomatoes should be planted deeply, and cotyledons should be buried. Shallow-rooted plants such as peppers and cucumbers should be planted in shallow depths, with soil and ground flat, and cotyledons on the ground. Planted deep, easy and stiff seedlings, planted too shallow and easily frozen. Third, cover cultivation. Planting earthworms can use various cultivation methods to increase the temperature. Such as a small high ridge cover film, east-west high ridge, planted sunny slope, seedling planted ditch or mulch on the hole cover, etc., such as cover film and then take a small arch shed better. Fourth, exercise seedlings. 10 to 15 days before planting, the seedbed should be ventilated, exercise seedlings, grass cover early to cover the late cover, leaving the wind at night, until all removed. After the exercise, the stems of the seedlings have thick leaves, strong green color, high survival rate after planting, and strong frost resistance. Exercise should be gradually carried out, always pay attention to the sudden cold weather. Fifth, spray fertilizer, medicine. Spraying fertilizer and medicine before Miaowang planting can play a role in saving liquid medicine, disease prevention and pest control and strengthening seedlings. Omethoate, deltamethrin, etc. can be used to prevent aphids, chlorothalonil, carbendazim and other diseases. Fertilizer can use potassium dihydrogen phosphate, urea 0.3% solution, single or mixed sprayer back. Sixth, protect the root system. Planting 4 to 5 days before planting. Watering the day before raising seedlings and cutting seedlings the next day. Asked the bandits 8.3 ~ 10cm square, high 10cm, seedlings in the middle, less wounded roots, do not scab, after planting the seedlings in order to tighten the code in the original seedlings, surrounded by soil cover to prevent evaporation of water; Avoid dry roots, shoots, roots, shoots, and shoots that cause damage to the root system, such as using a nutrient pot to raise seedlings. Seven, Yi Qin cultivator. The cultivator can cut off the soil capillary and prevent the lower layer from rising and evaporating. It can protect the soil and avoid soil compaction, allowing air to penetrate into the soil to enhance the heat absorption of the soil.
