After the cotton is topping in July, the following technical measures should be taken.
First, scientific control
1. As the growth control of cotton topping, generally control 1 or 2 times. For the first time, after 3 to 5 days of topping, 667 square meters of seedlings were planted in 12,000 or so plots, 4 to 5 grams of ghrelotamine was applied, and 30 kilograms of water were applied; Amine 6 to 7 grams, 40 kilograms of water. For the second time, the individual development and population size of the cotton plant were controlled, and moderate re-control was performed according to the weather, soil moisture, and the appearance of the cotton plant. Generally about 8 grams of ghrelin was applied on 667 square meters. Through the action of dildo-amine, the effective control of ineffective buds and empty fruit shoots is finally achieved, and the transformation from vegetative growth to reproductive growth can be achieved, and the growth and shape of balanced growth can be shaped to ensure that the number of bolls at the top of the cotton plant and the weight of the boll are increased. Create conditions for high yields.
2. The proper method of spraying the dilute amine is to dissolve the dilute amine first in a weighed basin or plastic bucket container, stir it well, and make the dilute amine containing the amount of diaminos per 100 grams of the dilute amine solution. Add to the sprayer.
The principle of spraying dilute amine should be uniform and dissatisfied, the spray height should not be low, and the principle of spraying should not spurt. It should be performed after 5 pm. Spraying under high temperature and strong light will reduce the effect. Rainfall within 6 hours after spraying will affect the absorption effect. If the rainfall is too long, it will be ineffective, and heavy spraying is required.
Second, according to local conditions, irrigation cotton to enter the peak of reproductive growth after topping, flowers, buds, bells gradually formed, this stage is the cotton during the entire growth phase of the most water demand stage, the conventional furrow irrigation of cotton fields, a small water, two water to Full, three and four waters should be sufficient (three and four waters are the second water after topping), and water must be stopped before August 15th to prevent cotton plants from becoming greedy and late.
Third, look at the appearance of fertilizer topping After the cotton needs more water and fertilizer, the conventional irrigation of cotton fields, base fertilizer and the first and second irrigation when the application of different amounts of nitrogen, phosphorus, potassium fertilizer, after the top should be based on the cotton plant branches, leaves Apply nitrogenous fertilizer for a long phase, applying 5 to 8 kg per 667 square meters. At the same time, boron fertilizer was sprayed on the leaves, and 50 grams of fast boron was dissolved in 50 kg of water spray per 667 square meters for a total of 2 sprays to increase the rate of ringing.
Fourth, timely picking and collecting bolls after picking flowers to adhere to the "three white", and do graded flower picking, graded stacking drying, graded sale, to ensure that the quality and quantity of cotton, yield bumper harvest.

At ancient times, people picked up wild fruits, and they found the magic of Goji , The pictograph word "qi" in Chinese character just like a man knelt down at a Goji tree , the left of the character "qi" seems like a tree, and the right like a person bowed down. That means as early as four thousand years ago, people found that Goji can keep fit and role of longevity ,Goji has magic power to people`s life.
