Although cotton has entered the bud stage this year, the progress of childbirth is slightly later than that of normal years. However, from June 15 to the end of July, the temperature has risen rapidly, and the growth of cotton activity has increased rapidly. Many cottons that were planted earlier, were transplanted with nutrient, seedlings, or “double-film†cultivation, and the density was relatively sparse. When surveyed on July 15, the average number of peaches per plant was 2 to 3, more than the same period last year. 1 or so. By July 25th, some farmers' cotton fields had reached 15 peaches per plant. Some farmers told me from the phone that his cotton even had more peaches. This year, many farmers have so many cotton peaches and cotton puddings. Is this a happy or a worry? Some farmers said that they were happy, and some farmers said that they were a bit worried.
The farmers who say hi say that, based on the existing cotton peaches, there are 100 to 150 kilograms of seed cotton per acre of cotton fields, and then the management is carried out later, and the seed cotton can be collected from 250 to 300 kilograms per mu. Worried farmers have had the lesson of cotton early peaches. First, they are afraid that there will be no stamina in the late stage of cotton, and they will get early and get cotton stalks early. Second, they will be afraid of frequent rain and rain, reduce quality, reduce production and reduce income. We believe that the two predictions of farmers' friends are justified. That is to say, the number of cotton nectars in the early stage can lay a certain foundation for high cotton yield, but early peaches are not necessarily equal to high yield.
Due to the different climatic conditions in different regions, the maturity of cotton varieties is different, and the cultivation methods are quite different. Every year, some farmers' cotton can often have a batch of early peaches in the early stage of fertility, can the early-developed cotton not prematurely decay , and reduce the rotten peach, enhance the stamina, and capture the harvest?
First of all, it is necessary to supplement nutrition due to seedlings. In the early stage, the cotton with more peaches generally lacks stamina, the stems are red, the top of the heart is prominent, and the symptoms of de-fertilization are obvious. However, as long as the peach fertilizer is supplemented, this type of cotton can enhance the stamina, because cotton has the habit of unlimited growth. The effective ringing period can continue to peach. For this reason, for cotton fields with poor soil fertility and severe de-fertilization, the time for top dressing can be extended to around August 15th. In places where conditions are irrigated, the dry cotton fields should be filled with water first, and about 15 kg of urea per mu. The root can also be sprayed with 1% to 2% urea and 0.2% to 0.3% potassium dihydrogen phosphate solution, which can play the role of multi-junction and strong peach.
Second, we must thoroughly pruning and playing power. In order to plant hybrid insect-resistant cotton, in order to prevent rotten peaches early, the wood branches (nutrition branches) and axillary buds as well as the middle and lower old leaves should be completely removed to enhance the ventilation and light transmission properties of the cotton fields. In the event of continuous rain, it is necessary to timely dispose of the trench, and do not ignore these conventional measures. In the cotton fields with large shades, it is still necessary to adhere to the capping of cotton after the topping of the cotton, or to promote the capping according to the condition of the seedlings. Generally, 2 to 3 grams of ketamine or 8 to 12 milliliters of auxin is used per acre, and some specially shaded cotton fields can be used for 4 to 5 grams of ketamine or 16 to 20 milliliters of auxin per acre to create a good The cotton living environment reduces the rotten peach and ensures the quality of cotton fiber.
Third, we must guard against diseases and insect pests in the middle and late stages. Cotton with early peaches, when the potassium fertilizer is insufficient, in the case of heavy rain after a long drought, it is easy to cause stem blight of red leaves, and the number of times of spraying potassium or potassium chloride on the basis of increasing potassium fertilizer is required. The concentration is preferably 1% aqueous solution.
