The cause and prevention of the latest melon rotten melon

Melon planting after the fruit is easy to appear rotten fruit, sometimes growers do not know what reason, management is no problem, melon is rotten melon, most people think it is rain accumulated water melon absorption too much, soaked rotten, but in fact there are many specific reasons, not only this kind, so today mainly to introduce melon rotten melon detailed reasons, and how to prevent rotten melon.

I. Reasons

Infected bacteria, causing disease, and then rot melon, mainly caused by rot disease is bacterial angular spot disease, rot disease. These germs can be transmitted through soil, seeds, and infected. The germs on sick and disabled bodies can be transmitted through rain splashing and insects. Sometimes applying more potassium and nitrogen fertilizers will inhibit the absorption of improved melons, and lack of calcium will cause rotten melons. Improper management, sometimes over-dense planting, excessive humidity in the field, no disinfection of seeds and seedlings, weak growth of malnutrition, and reduced disease resistance will easily rot melons.

II. Preventive measures

1. disinfection

Seeds should be soaked and soaked in liquid medicine. The seedlings purchased should be sprayed with carbendazim to prevent bacteria. Then the seedling tray, culture medium or seedling bed should be disinfected. You can sun them first. You also need to spray disinfectants such as chlorothalonil for disinfection. To clean up the sick body in time, after harvest, do not leave the sick body in the field, to clean up the garden.

2. fertilization

Reasonable fertilization, nitrogen, phosphorus and potassium combined use, early to control some nitrogen fertilizer, do not let the plant flourish, there is not to use too much nitrogen and potassium fertilizer, affect calcium absorption, can reduce nitrogen and potassium fertilizer appropriately. Nitrogen fertilizer will be used a lot less in the later stage of growth, but potassium fertilizer is needed more in the later stage, so in fact, it can be controlled in the later stage and more potassium fertilizer can be applied in the middle stage.

3. strengthen management

Melons are generally planted on flat ground, so they should be planted sparsely, not too densely, sparsely planted, the humidity in the field will be lower, and no space will be provided for the growth of germs; then they should be reasonably fertilized, and topdressing should be applied according to the fertilizer requirements of melons in each period, and fertilizer should not be lacking, or planted in barren land.

Melon rot is mainly caused by diseases, but there are some environmental factors that are not well coordinated, which will create conditions for the growth and reproduction of pathogens. Melon rot disease likes high temperature and high humidity most. So prevention starts with environmental factors.
