Cotton Seedling Management and Transplanting

Cotton Seedling Management and Transplanting

Cotton from the cotyledon to the two true leaves are most susceptible to various diseases, which endanger the roots with blight, rot, damage to the leaves of anthrax, brown spot. Most of these diseases are severe in rainy, cold and warm climates, and they often occur mixedly. Light causes diseased seedlings, and heavy ones easily form stiff seedlings, resulting in lack of seedlings and ridges.

Cotton seedlings management and disease prevention methods are as follows:

1. Control seedbed humidity and temperature

After the cotton seedlings emerge, the cotyledons shall be unfolded, and the covering films at both ends shall be promptly opened to ventilate, reduce humidity, cool down, and practice seedlings so as to prevent the formation of tall seedlings. At the same time pay attention to prevent the late spring.

2. 2~3 days before cotton seedlings are transplanted, spray bacteria sterile 5ml/15kg+20g carbendazim + 1/2 grain spring rain 1/15kg

It can prevent a variety of diseases (including yellowing and wilt disease), and make transplanting seedlings take root early, and quickly and slowly to achieve Miao Qi and Miao Zhuang.

3, after transplanting cotton seedlings in addition to timely cultivator, improve ground temperature, improve soil permeability, but also timely prevention of insect pests; prevention and control of ground tigers can be used 90% trichlorfon per acre 50 grams (1 two), add water 2 pounds, Spray 2.5 pounds of sauteed cotton cake or wheat bran and mix well. Sprinkle the cotton seedlings at intervals and prevent the tiger from harming the seedlings.

When cotton spider mites occur, the cotton seedlings become fire-like, and they can be sprayed with 1500-fold liquid.

After the occurrence of cotton aphid, the plant growth point contracted, resulting in growth stagnation, and can be sprayed with Coke 1500 times liquid.

In the case of harm caused by blind stink bugs, the cotyledon stage is characterized as “broken leaf disease”. The top buds are affected with multiple cotton heads, and can be sprayed with poisonous ear 1500 times liquid. It can also be used to prevent cotton aphids.

Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
