What are the reasons for the latest balsam pear?

Balsam pear planting is a common phenomenon, it is only in the growth and development of young melons suddenly stop growing, from the melon to the whole melon gradually yellowing, shrinking, until withered, seriously affecting the yield and income. So what are the reasons for Momordica charantia? Let's get to know it.

1. The temperature is not suitable

Balsam pear requires higher temperature during the gourd bearing period. the temperature should not be higher than 32 degrees or lower than 20 degrees in the daytime and lower than 18 degrees at night, which will lead to the hindrance of photosynthesis, increased respiration, more nutrient consumption and unfavorable nutrient accumulation in its leaves. resulting in malnutrition and melons. Melon vegetables in the growth of low temperature freezing injury is that because the ground temperature is too low, it will lead to root dysplasia, affect the absorptive capacity, resulting in undernutrition and melons.

2. Carbon dioxide concentration is too low.

Nowadays, in order to increase production and facilitate management, many growers will use greenhouse cultivation technology, and balsam pear is more sensitive to carbon dioxide, once the concentration of carbon dioxide in the greenhouse is too low, it will lead to the phenomenon of melons.

3. Improper management

When planting, the cultivation density is too high, resulting in canopy closure in the field, poor ventilation and light transmittance between plants, which is not conducive to plant photosynthesis, less assimilates and easy to appear melon phenomenon. In addition, for improper fertility management, resulting in lack of water and fertilizer, the lack of some necessary trace elements will also affect the normal photosynthesis of the plant, resulting in the emergence of melon.

4. Overgrowth

Under the factors of partial application of nitrogen fertilizer, high temperature and excessive water, the stem of balsam pear will grow stout, the leaves are thick, the plant grows too prosperous, while the melon strips grow slowly, and the flowers and fruits gradually melt away because they can not get assimilates.

5. Diseases and insect pests

A variety of diseases will directly harm the growth of leaves, leading to leaf wilt, necrosis, serious cases lead to plant drying, unable to carry out normal photosynthesis and melon. In addition, aphids, whitefly and other pests will also suck the sap of the leaves, and their excrement will also pollute the leaves and destroy the photosynthesis of the leaves, resulting in the insufficiency of nutrition and the transformation of melons.

The above are the reasons for the introduction of balsam pear, hope to help you, want to know more related knowledge, please pay attention to us.
