Causes of melons and melons in melons and melons, preventive measures and methods of operation
After many years of experimentation by our company's plant protection experts, the following are the main reasons for the production of watermelons, melon melons and melons:
â—† Causes of watermelon, melon melon melon:
1. Poor pollination: When the amount of pollination is insufficient or the spraying is not uniform, the seeds in the melon can easily concentrate on one side of the melon. Usually on the side with more seeds in the melon, the nutrition supply is also more, the growth rate is fast, and the external appearance is rapid and rapid. On the side with less seeds, the expansion is slow due to lack of nutrient supply, which leads to uneven formation of both sides of the melon. Melon
2, uneven temperature distribution of melon surface: generally speaking melon Chaoyang surface temperature is higher, the expansion is also faster, and melon's paste on the ground side, due to low temperature expansion is slow, resulting in the formation of a large, small Melon; Due to insufficient nutrient supply at low temperatures, it is easy to form pods even if fruitless products are not used.
3, too many nutrients Zuogua insufficient supply: Guazao too many fruit on the left to make nutrient supply is insufficient, get more nutrition side of the rapid growth, get less nutrition side of the slow growth is the formation of Gualou, (removable part of the fruit).
4, plant damage: melon in the expansion process, the local melon surface is mechanically damaged, the injured side of more slowly growing, so as to form melon.
5. Malnutrition: Insufficient supply of drought and water fertilizers The weak growth of melons or disease disasters, or the occurrence of small melons, will be due to the small effective area of ​​melons, and the nutritional supply of melons will be insufficient to form melons.
â—† Watermelon, melon melon melon prevention measures:
1. Artificially assisted pollination: Through auxiliary pollination, ensure that the amount of pollen is sufficient, and avoid the inequality of pollination in natural pollination, and prevent the formation of loquat fruit.
2, Fold melon: Fold melon can make the melon around the light evenly, to prevent the melon surface temperature difference is too large, and the formation of melons.
3, do not leave low-section melon: Because the low-section melon melon, melons are still small, the effective area of ​​melons is small, easy to form melon.
4. Protection of fruits and vegetables: We must strengthen the supply of fertilizers and water, prevent and control diseases and pests, and keep the stems and leaves of melons well. At the same time to prevent excessive growth of nutrient plants, to take measures to promote sitting melon, to prevent melon seat too far can prevent the production of abnormal melon.
â—† Causes of Melon and Melon Cleft Melon:
1. Variety reasons: Thin and crispy varieties are easy to form melons.
2, long drought and water: long drought time, fierce irrigation or heavy rain, water supply imbalance, resulting in split melon.
3. Irrigation during mature period: excessive irrigation in the near mature period can also cause fruit cracking. Practice has shown that splitting of the melon is most likely to occur at the fifth and sixth splits.
4. When it's too cloudy for a long time: As the temperature rises too fast, it can cause cracking.
â—† Melon crack melon preventive measures:
1. Select varieties: Select watermelon varieties with high toughness.
2. Reasonable watering: The groundwater should be filled with small water, but not with flooding, so as to avoid the difference in soil moisture content before and after watering. The high temperature period should be watered when the temperature is low in the early morning or evening, and do not water at a high temperature at noon, so as to avoid a large amount of water absorbed by the root after watering, and the water supply is too fast and too much and cracking occurs. Immediately drain water after rain. Stop watering after the watermelon is set.
3, to promptly harvest melon: Should be melons in the sunny noon or afternoon when the melon water content is small, early and late harvest melon, because the melon contains more water, in the process of harvesting melon and handling, prone to crack melon.
â—† West cantaloupe melon king operating technology:
Melon method: In the morning of the watermelon and melon female flower opening day, 7-10 am, use the “Sweet melon king†to dip 2-3 pounds each, then pour it into a small bowl and mix the whole baby in the liquid. Dip a little, then gently touch the edge of the small bowl, so that the excess liquid on the young melon can be licked in the bowl. When using this method, avoid high temperatures at noon. (In this method, female flowers are evenly inflated at a fast rate, and it is not easy to produce melons or deformed melons. This method is better than the spray method and the smear method.)
Spray and spray melon method: In the morning of the watermelon and melon female flower opening day, 7-10:00 am, use “watermelon seat melon king†each watered 2-3 jin spray evenly on female flower and young melon with watering can or spray gun. It is advisable to cover the flowers with drops of flowers and young vines. When using this method, avoid high temperatures at noon.
