Prevention and control measures of loquat fruit cracking

Loquat is a unique cherished fruit in the south. Its fruit is beautiful in appearance, bright in color, sweet in taste and unique in flavor. However, in the mature period of loquat, in case of overcast and rainy climate, the fruit will expand rapidly, which will lead to fruit cracking. Fruit cracking causes loquat to lose its commercial value, reduces the economic benefits of fruit farmers, and is extremely vulnerable to diseases and insect pests, so how to control loquat fruit cracking? Let's take a look.

1. Fruit bagging

Bagging loquat fruit in time can pass through a suitable and stable growth environment, which is one of the main control methods to reduce fruit cracking caused by climate change. In addition, after bagging, it can also reduce the damage caused by diseases and insect pests and the temperature, do a good job of disinfection and sterilization and pest control before bagging, try not to directly touch the surface of the bag, so as not to cause burns, and the mouth of the bag should be tied tightly.

2. Scientific watering and fertilization

Reasonable and scientific watering and fertilization can also effectively prevent fruit cracking and apply organic fertilizer as far as possible, which can not only improve soil results, provide diversified nutrition for plants, increase yield, but also reduce fruit cracking rate. In the inter-garden management, water is extremely important, we should pay attention to the uniform supply of water, in the climate and soil drought, timely watering to keep the soil moist, to provide plant growth needs, and in the rainy season to timely drainage and waterlogging, lest the plant absorb too much water, rapid expansion and lead to fruit cracking.

3. Reasonable shaping and pruning

The sprouting power of loquat plant is very strong, if it is not pruned in time, it will grow many branches in a short time, resulting in a tall crown, and these branches are many and thin, which will consume a lot of nutrients of the plant, so that the fruit can not get enough nutrients to grow, resulting in fruit cracking. Therefore, it is necessary to dwarf the plant during growth, so that the crown is shorter, but the branches are strong, which is conducive to the supply of nutrients, so that the fruit grows well and reduces the occurrence of fruit cracking.

4. Medicament prevention

In modern planting industry, a large number of chemicals are widely used. Spraying chemicals on loquat fruit growth time can prevent the occurrence of fruit cracking. In the fruit color change, timely spraying ethylene solution can effectively prevent loquat fruit cracking, but also make the fruit mature 7-10 days ahead of time, make it appear on the market earlier and seize the market in time. In addition, 0.2% urea and 0.2% borax solution can be used for foliar spraying during the fruit expansion period, which can promote fruit growth and development and reduce the occurrence of fruit cracking.

The above are loquat fruit cracking control measures, hope to help you, want to know more about loquat planting knowledge, please pay attention to us.
