I. Preparation before planting
1, digging planting ditch. Divide planting trenches by row spacing, depth and width are each 60-80 cm, open topsoil and subsoil, dig a layer of 10-15 cm thick wheat straw at the bottom of the trench, mix with the soil, and then fill in the subsoil 10-15. Centimeter thick, put a layer of 5-10 cm thick with manure, cake fertilizer and other organic fertilizer mixed with fertilizer, and finally fill in the topsoil, irrigated.
2, seedlings renovation and disinfection. The grafted seedlings retained 3-4 full shoots in the scion, 3-4 full shoots from the roots of the rooting shoots, and the excessively long shoots should be trimmed properly. Roots were soaked with 50 mg/kg naphthalene acetic acid or 25 mg/kg hydrazine butyrate for 8-12 hours. The seedlings were sprayed with 5 degree lime sulfur for sterilization.
Second, planting time
Seedlings planted in late November and early December are planted in autumn, and planted in spring from February to the Ching Ming Festival. The first planting roots in autumn plants and the first planting in spring plants are better than those in spring planting. However, the disadvantage of autumn planting is that the soil has not weathered over the winter, and in order to avoid winter cold and winter drought, it is necessary to strengthen the rhizosphere soil and regular watering.
Third, planting density
The determination of the planting density of grapes should take into account various factors such as breed characteristics, shelf type, climate factors, site conditions, and cultivation habits.
Fourth, planting methods
The planting hole was planted according to the planting distance and the width was determined according to the size of the root system. Choose sunny or cloudy planting. The autumn planting should be shallow and deeply buried, that is to say, the seedlings should stand upright in the hole, and the depth should be the depth when the original seedbed is used, so that the root system can be stretched and evenly distributed. When the soil is half filled, the seedlings are raised gently to make the root system closely contact with the soil. Fill soil and ground level, pour water thoroughly, then cover soil 20 centimeters thick, showing a bread-like shape. In the spring of the following year, the earthworms will be opened to the roots. Planting in spring should be shallow shallow burial, is conducive to early root activity, such as the condition of available film cover insulation moisturizing.
