The phenomenon that persimmon drops fruit often happens, why can you appear this kind of phenomenon? Listen to the fruit farmer

Persimmon is one of the common fruit varieties. At present, many rural areas are specially planted persimmon tree, but many new people can meet such a problem. What is the reason for their persimmon tree always falling? Do you want to do something?

Persimmon trees drop fruit and themselves for a reason. First of all, its own nutrient growth is too vigorous, resulting in the lack of fruit nutrition, and the flower pedicle can not bear the weight of persimmon in the later stage, resulting in a drop. This also applies to poor initial pollination and fruit dropping at later stages when not fully developed.

Finally, when there are too many persimmons on the same branch, they will compete with each other for nutrients in later stages of growth, and some poorly growing persimmons will also cause fruit loss. There are environmental factors, which are also easy to cause persimmon trees to fall fruit. First, not keeping up with water and fertilizer will lead to a serious decline in the health of persimmon trees.

Severe fruit loss occurs because the tree can no longer maintain the nutrient requirements of the fruit. Secondly, if the weather is not ideal for a long time, the growth and development of the fruit will be severely hindered, unable to grow, and finally can only drop. If the soil is too poor and the persimmon trees are stunted, isn’t it normal for the persimmon to fall?

In terms of diseases and insect pests, this is a serious aspect of persimmon fruit dropping. For example, the most common persimmon pedicle worm is a kind of persimmon, which is usually found more often, causing serious damage to the persimmon pedicle, reducing the vigor of the pedicle and even wilting. Finally, persimmon can only drop without tension.

Persimmon tree fruit drop is relatively normal, the normal growth of persimmon will also be affected by some external factors. Have to. When we visit the orchard every day, we try not to walk past the persimmon trees below, so as not to cause unnecessary injury.

Prevention and control of persimmon falling fruit. During the first flowering period, persimmon trees should be ringed during the flowering period until the full flowering period is complete. The width of ring mouth is 0.3-0.5mm. After peeling, wrap the peeling mouth with plastic cloth strip to maintain the humidity of the peeling mouth and promote healing.

In THE MEANTIME, WANT TO GROW PERIOD TOO DENSE BRANCH, INEFFECTIVE BRANCH, UNDERTAKE PRUNING, ACCORDING TO “WINDWARD SIDE MUCH LEAF BRANCH, LEEWARD SIDE LITTLE LEAF BRANCH” PRINCIPLE UNDERTAKES. After pruning, useless shoots should be removed before lignification, and long shoots with room to grow at 40 cm should be harvested to reduce nutrient consumption. In addition, the buds should be properly retained, generally, the 3 buds in the middle of the mother branch should be retained, and the rest should be dredge.

Drug regulation. The USE OF CHEMICAL CONTROL CAN IMPROVE THE NUTRITIONAL STATUS OF FLOWERS AND fruits, prevent the stem from SEPARATING FROM THE stem of perSIMmon, enhance THE nutrient absorption function OF flowers and young fruits, stimulate fruit expansion, and increase fruit set rate. General use of chemical agents should be in full flowering and young fruit period each spray gibberellin and urea mixture, to fruit expansion period, spray 0.3%-0.5% urea solution and ammonium molybdate and other trace element fertilizer on the leaf.

Pest and disease control. During fruit growth, on the basis of artificial disease and insect removal, 50% dichlorvos emulsion was sprayed 1000 times to prevent persimmon impermeability. And IN a few days after spraying 70% methyl tubujin wettable powder 600-800 times liquid, can prevent anTHRacnose, horn spot disease, round spot disease, etc. From July to August, 25% isocaricide was sprayed on fruits, stems and buds 1500 times, once every 10 to 15 days and twice to three times, which could prevent the occurrence of larvae in the peak period.

The treatment of flower branches includes pruning branches, peeling around branches and thinning buds. In order to avoid waste of fertilizer and water and poor air permeability, the ineffective and ineffective branches must be pruned before flowering, and the principle of more branches on the windward side and less branches on the leeward side should be followed to ensure ventilation and avoid bacterial breeding and transmission. Circular desquamation can not only promote flower bud differentiation, but also reduce physiological fruit drop in advance.

In general, circumferential peeling should be done early in flowering. After circumferential peeling, wrap the peeling mouth with a plastic strip to maintain peeling humidity, promote healing, and strengthen fertilizer and moisture management. To ensure final fruit quality, keep three buds on the first two to three parent branches of fruit, three buds in the middle, and the rest sparsely.

Persimmon tree fruit drop is relatively normal, the normal growth of persimmon will also be affected by some external factors. So occasionally drop a few drops of people should not be too nervous, drop more frequently should pay attention to, need to check whether there is the above situation, so that the right medicine. When we visit the orchard every day, we try not to walk past the persimmon trees below, so as not to cause unnecessary injury.
