First, seedlings exercise. Before 10-15 days of planting, seedbeds should be ventilated and the seedlings should be raised. Grasshoppers should be exposed early and covered with lids, and they must be left at night to remove them until they are completely 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.
Second, 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.
Third, protect the root system. Planting 4 to 5 days before planting. Watering the day before raising seedlings and cutting seedlings the next day. The bandits are required to be 2.5-3 inches square and 3 inches high. The seedlings are in the middle, and the roots are not to be wounded. Do not disperse the beaks. After the beggars are lifted, the seedlings will be tightened in the order of the original seedlings, surrounded by earth to prevent moisture. Evaporation; Avoid dry roots sprouting and wet seedlings sprouting, so that the root system damage, such as the use of nutritional seedlings better.
Fourth, soil fertigation. The use of empty land fertilization, so that the soil is fat enough; there is a previous work to be ploughed fertilizer as soon as possible, laying decomposed organic fertilizer, 2000-2500 kilograms per acre, and then after the application of compound fertilizer, manure water should be uniform, ventilation, insulation.
Fifth, 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.
Six, water stable seedlings. There are two methods for planting seedlings: the dry planting method is to plant seedlings, cover soil, and water, so that the topsoil is moist, but it is easy to lose water and the soil is hardened; the wet planting method that is water stable seedling method is to open the ditch, water, put the seedlings, water After infiltration, the soil is dry, which is conducive to ventilation. The soil is easy to warm and warm, and the soil is kept warm. The lower wet soil is conducive to root growth. This is the best way to plant seedlings.
Seventh, the depth is appropriate. 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.
Eight, 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.
Nine, to prevent freezing. As the saying goes: “Clearance breaks the frost, and the valley rain stops the snow.†When there are cold currents, it is necessary to pay attention to antifreeze. The method is: Watering or watering can prevent dry freezing and reduce damage.
