What winter cold protection measures are there for grapes? The latest freeze protection guide
Grapes, as a very popular fruit, are widely planted across our country. Now, as time goes on, the temperature is getting lower and lower, and winter has gradually arrived. In winter, grapes gradually enter the dormant period. After entering the dormant period, 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 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 down from the trellis in the same direction and lay them flat on the ground. Be careful not to let the canes be crushed and broken. Some grain straw can be spread at the base of the plants and above and around the canes to keep them warm. Then cover with soil and press it firm. When covering with soil, there must be no gaps, to prevent drafts 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
Besides solid burial on the ground, we can also carry out cold protection by digging trenches underground for solid burial. First, beside the grape plants, 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, sort and tie the canes and place them into the trench. After placing them in the trench, in order to improve the cold protection effect, also cover with an appropriate amount of straw and other stalk materials to keep them warm, then cover with soil and press it firm. Note that although this cold protection effect is very good, it cannot be used year after year, otherwise it will harm the plant root system.
3. Deep trench planting cold protection method
The deep trench planting cold protection method requires everyone to begin preparing at the time of planting. 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 used relatively often by many fruit growers in winter now. First, some straw and grain stalks should be covered on the grape canes, then a layer of film should be covered, and then soil should be used to cover it tightly. During operation, be careful not to damage the film, and also pat the soil firm, otherwise the cold protection effect basically cannot be achieved. The cold protection effect of this method should be the best, because straw, film, soil, and so on can all protect against cold, and the overwintering survival rate of grapes will also be very high.
The above is a brief introduction to winter cold protection measures for grapes. That is all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone!
