Causes and control methods of planting melons and melons

First, the reason for the melon.

1. The temperature is too high or low. Too high temperature, less photosynthetic accumulation, more respiratory consumption, easy to make melon vine grow, malnutrition and melon; too low temperature, weakening root absorption capacity, affecting photosynthesis leading to lack of nutrition and melon.

two。 The soil is too dry or waterlogged. Excessive soil drought will make young melons unable to expand due to lack of water; excessive waterlogging will reduce soil permeability and inhibit the absorption of nutrients by roots.

3. Improper fertilization. The main reason is that the excess supply of nitrogen fertilizer will make the vegetative growth of muskmelon too prosperous and weaken the reproductive growth.

4. Too high concentration of hormones can easily lead to melons.

II. Prevention and control methods

1. To control the suitable temperature, the highest temperature in daytime is not higher than 35 ℃, preferably between 25 ℃-32 ℃, and the lowest temperature at night is not less than 10 ℃, preferably between 15 ℃-20 ℃.

two。 Timely drainage and irrigation to ensure that the soil is dry and wet.

3. Balanced fertilization, especially in the peak fruiting period, should be supplemented with appropriate amount of phosphorus and potassium fertilizer.

4. Strictly control the concentration of hormone, use low limit concentration at high temperature and high limit concentration at low temperature.
