The causes and Control methods of the latest premature senescence of Rice
The phenomenon of premature senescence occurs when rice is planted. The so-called premature senescence refers to premature senescence, which mainly occurs in the late heading stage of rice, such as withered stems and leaves, poor grain filling and reduced yield due to the increase of shrunken grain. In folk, it is called standing stalk dead or returning to straw, then rice is premature senescence.

Causes and control measures of premature senescence of latest watermelon
In the middle and later stage of watermelon growth, premature senescence is very easy to occur if it is not managed properly. Premature senescence does great harm to watermelon, which will cause a large number of fruits not to ripen normally and seriously affect the yield and quality. So what about the premature senility of watermelons? Let's get to know it.

The latest measures for the prevention and control of premature senescence of hot pepper
In the later stage of pepper growth, because of improper fertilizer and water management, diseases and insect pests or other factors, pepper plants often lead to premature senescence, premature senescence will seriously affect the yield, and serious will lead to premature plant death. In order to promote the high yield of hot pepper, it is very serious to avoid premature senescence.

The latest ways to prevent premature senescence of tomatoes
In the cultivation of tomato is no stranger to premature senility, after the emergence of premature senility of tomato, the most intuitive is to affect the variety of tomato, and premature senescence of tomato plant nutrient absorption function greatly decreased, its yield will also decline in a straight line. So what about the premature senescence of tomatoes?

Beware of cotton premature senescence in summer
After the emergence of premature senescence of cotton, remedial measures are of little significance, focusing on prevention. The first ten days of August is the peak period of cotton flowering and bolling. if the vegetative growth and reproductive growth are well coordinated, it is not easy to senescence prematurely. The earlier the occurrence of premature senility, the more serious the yield reduction. In serious years, premature senility occurred in the middle and late August. How to prevent cotton premature senescence and increase cotton yield is an urgent problem to be solved in cotton production. Here are some measures to prevent cotton premature senility. Pay attention to the way of watering. The summer drought leads to the premature senescence of cotton. If there is no rain in Fuli, it should be watered in time.

Main causes and Preventive measures of premature Senescence of Cotton under drip Irrigation
First, the main reasons for the premature senescence of cotton planting with high density. Variety factor varieties are not resistant to premature senility. In recent years, there are many varieties of cotton, some varieties of aging, degradation, some varieties of their own disease resistance and early aging resistance is poor, or not suitable for high-density planting, resulting in premature senescence of cotton. two。 Environmental factors the suitable sowing time of precocious cotton in ① temperature is 5 cm ground temperature and 12 ℃. If sowing is too early or cold injury occurs at seedling stage, the root system function of cotton is easily damaged due to low air temperature, slow root growth and serious disease.

Prevention of premature senescence of cotton in the later stage
Premature senescence of cotton plant means that when the growth center turns to reproductive organs after the cotton plant enters the flower and boll stage, if the cotton plant is malnourished and the bud and boll compete with the vegetative organs for the organic nutrients produced by leaves, the vegetative growth will be more restrained. After this kind of cotton plant bears several cotton bolls in the middle and lower part, the upper part of the cotton plant appears the phenomenon of vegetative growth decline, such as top tip, hard hair, red stem to the top, thin and yellow leaves, which is the premature senescence of cotton plant. Premature senescence of cotton plants generally occurs in stiff soil, poor fertility and poor root growth.
