What winter cold protection measures are there for grapes? Key practical techniques
As a very popular fruit, grapes are grown on a relatively large scale across our country. Now, as time goes on, temperatures are getting lower and lower, and winter has gradually arrived. In winter, grapes gradually enter dormancy. After entering dormancy, the cold resistance of the grape plants also declines. Therefore, we need to do a good job of cold protection in winter. So let's take a look below, together with the editor, at the winter cold protection measures for grapes!
1. Ground solid burial cold protection method
The ground solid burial cold protection method is a commonly used winter cold protection measure for grapes. First, do the winter pruning of the grape plants well, then take the canes off the trellis in the same direction, comb them, and lay them flat on the ground. Be careful not to let the canes be broken by pressure. You can cover the base of the plant and the top and surroundings of the canes with some grain straw to keep them warm. Then cover with soil and compact it. When covering with soil, there must be no gaps, to prevent thief winds from entering and affecting cane growth. Usually the height of the soil mound is kept at about 40cm. After the soil freezes, pour in an appropriate amount of freezing water.
2. Underground trench solid burial method
In addition to ground solid burial, we can also carry out cold protection by digging trenches underground for solid burial. First, beside the grape plant, at a position about 40cm from the root system, dig a trench along the row direction with a depth and width of about 50cm. Then, as with ground solid burial, comb and tie the canes and place them into the trench. After putting them into the trench, in order to improve the cold protection effect, also cover with an appropriate amount of straw and other stalk materials for insulation, then cover with soil and compact it. Note that although this cold protection effect is very good, it cannot be used year after year, otherwise it will damage the plant root system.
3. Deep trench planting cold protection method
The deep trench planting cold protection method requires everyone to start preparing at planting time. First, when planting grapes, we need to dig deep trenches for deep trench planting. The depth of the deep trench is kept at about 40cm, and then planting can be carried out according to the usual grape planting method. The grape plants will grow directly in the deep trench. After winter arrives, you can choose according to the actual situation whether to bury soil in the trench, and its cold protection effect is very good.
4. Plastic film cold protection method
The plastic film cold protection method is also a cold protection measure that many fruit growers use relatively often in winter now. First, cover the grape canes with some straw and grain straw, then cover with a layer of film, and then cover it tightly with soil. During operation, be careful not to damage the film, and also pat the soil firm, otherwise basically the cold protection effect cannot be achieved. The cold protection effect of this method should be the best, because straw, film, soil, etc. can all protect against cold, and the overwintering survival rate of grapes will also be very high.
