Grape planting technology

The soil for growing grapes is suitable for loam and fine sandy loam, which is generally planted after the soil is thawed from March to May. When planting, the grape seedlings are planted obliquely to the north according to the plant spacing of 0.7 meters. After planting, the grape seedlings are watered, and then covered with 5 cm thick wet grass, which is covered with plastic film. During the growth period, maintain a suitable temperature, have a certain intensity of light, strict water control, reasonable fertilization, do a good job of erection, ploughing, weeding, vine binding, tendrils, flower thinning, fruit thinning and other work.

1. Soil: it is suitable for loam and fine sandy loam. After selecting the plot, sprinkle fermented dung, then turn about 40 cm deep, ridge along the line according to the row spacing of 1.8-2 meters, in the direction of north-south.

2. Planting: it is generally planted from March to May after soil thawing to germination. The grape seedlings will be planted obliquely to the north according to the plant spacing of 0.7 meters, pour a lot of water after planting, and then cover with 5 cm thick wet grass, covered with plastic film.

3. Temperature: the lowest temperature required for growth is about 12 ℃-15 ℃, the lowest ground temperature is about 10 ℃-13 ℃, the optimum temperature for flowering stage is about 20 ℃, and the optimum temperature for fruit expansion period is 20 ℃-30 ℃. If the temperature difference between day and night is large, the coloring and sugar content are better.

4. Lighting: there should be a certain intensity of light, but not too strong. If the light is insufficient, it will lead to poor plant growth, no fruit or unisexual fruit, poor quality, etc.; if the light is too strong, sunburn disease can be easily occurred, bagging or plant leaves can be used to cover the fruit.

5, watering: higher requirements for moisture, but to strictly control water, avoid Rain Water and dew. The water demand is more in the early growth period or vegetative growth period, and less in the later growth stage or fruiting period. Rice straw should be properly covered in water-deficient and drought-prone areas to maintain soil moisture.

6. Fertilization: base fertilizer, topdressing and foliar fertilization were adopted. The base fertilizer is used after hibernation or harvest, and the topdressing is the application of chemical fertilizer after flowering after rain or watering.

7. Management: grape is a vine, so it should be set up; during the growth period, we should do a good job in ploughing and weeding, as well as binding vines, removing tendrils, thinning flowers, thinning fruits, and so on.
