Grape bagging is more stressful
There are many farming operations involved in grape planting, such as flowering and earing, water and fertilizer management, swelling treatment, etc. Of course, consumers are paying more and more attention to the value of the color, so it is better to plant methods in the planting process. Eat, still look good grapes. And this requires a technology - bagging.
It is necessary to carry out the fruit thinning before bagging. If the fruit pieces are too tight, it is easy to cause cracks. There are many friends who have lost too much grain, and the fruit pieces are crushed and ruptured, and the liquid overflows. After a long time, it causes gray mold, white rot, acid rot and other diseases.
If the weather is too dry before bagging, water the whole garden before the fruit thinning to prevent sunburn. A few leaves can be placed on the top and around the fruit to prevent sunburn. When thinning the fruit, the small particles on the ear should be removed, and the damaged fruit should be removed.
There are many types of bags and there are many varieties. How to choose the right bag to bag, there is also a way.
Green varieties such as Sunshine Rose can be used in colored bags; there are also some red varieties that need to be refracted, and transparent bags are preferred.
When spraying and sterilizing, you should not choose the products of emulsifiable concentrates and powders. Try to choose suspending agents, water-dispersible granules, water emulsions, etc., so as to reduce the damage to grape fruit powder.
The liquid medicine is mixed evenly and then the medicine is sprayed. After the medicine is finished, the liquid can not be formed on the fruit surface. Try to shake the ear or wire and shake the liquid on the ear to avoid the formation of spots and contaminate the fruit.
When bagging, avoid the hot weather or the weather that suddenly clears after the rain, and wait until the fruit adapts to such an environment before bagging. Also pay attention to the situation of the day, the morning and afternoon low temperature period is the best bagging time.
