Planting and cultivation techniques of raisin

Growth environment and conditions: flat land, leeward to the sun, moderate dry and wet ventilation zone should be selected, and the soil requires sandy soil with good permeability, fertile and good drainage, which should not be exposed to strong light. Reasonable close planting: select the seedlings with full bud eyes and rooting, and carry out reasonable close planting in February according to the plant spacing of about 1 m and the row spacing of 2-3 m. Water and fertilizer management: fully watered after planting, timely drainage in rainy days, fertilization about 8 times a year.

I. the growth environment and conditions of raisins.

The main results are as follows: 1. Raisins can be planted in most parts of our country, and flat land or hills should be chosen for planting raisins. The soil requires good drainage conditions, good air permeability and fertile sandy soil.

2. The raisin is suitable for growing in the moderate dry and wet ventilation zone. During the sprouting and flowering period, if the humidity in the air is too high and the soil moisture content is too high, it is easy to cause diseases, thus affecting the yield. The water demand is large during the growth period, and the watering water can be increased appropriately, and the watering water should be controlled when the fruit is ripe.

3. The raisins should be planted in the place where the leeward is facing the sun. The vines of the raisins are more afraid of the wind. In case of a windy climate, it is easy to cause the scaffolding to collapse and damage the vines, thus affecting the yield. The raisins are not suitable to be planted in shaded areas. Lack of light can easily lead to the growth of thin vines and affect the normal photosynthesis of leaves. When it is hot in summer, it should be shaded properly. During the fruit growth period, it is not suitable for direct light, which can easily lead to burns.

Second, reasonable close planting

1. The seedlings with full bud eyes and rooting should be selected before planting, and then the roots of the seedlings should be wrapped in a wet cloth to avoid air-drying or dehydration.

2. generally, it is better to plant raisins in spring and autumn, and planting in this time stage is beneficial to improve the survival rate of plants. The most suitable planting time is in February in spring. When planting, it must be planted in a reasonable and close manner, according to the distance between plants about 1 m. The row spacing is about 2-3 m.

3. First, dig the planting ditch, then dig and transplant according to a certain distance, put the bud eye on the sunny side, then pour water through, cover the whole planting ditch with a layer of plastic film, and finally seal the film mouth with wet fine soil.

III. Water and fertilizer management

After planting, you must pour enough water to keep the soil moist, replenish water in time if it does not rain for a long time, and drain in time in case of rainy weather, otherwise it is easy to produce mildew root phenomenon, and you can apply sufficient base fertilizer from the end of October to the beginning of November. the number of fertilization is about 8 times a year.

IV. Prevention and control of diseases and insect pests

About 3 days after seedling planting, 50% carbendazim 800 times or 50% thiram 700 times can be sprayed every 7-10 days, or 70% methyl tropin can be used alternately to effectively prevent white rot, black pox and so on. If insect pests are found, insecticides can be sprayed for control.
