Remedial measures for Drug damage of Cotton
First, elution. Most chemicals are not resistant to water scouring. If you find that the medicine is not used properly, you can immediately wash the stems and leaves repeatedly with a sprayer filled with water, so as to flush away the chemicals left on the surface of the cotton plant and reduce the drug damage; when flushing, the air pressure of the sprayer should be sufficient and the amount of water sprayed should be large. For the cotton fields with soil application and the drug damage caused by some herbicides, the soil can be irrigated immediately and the residual chemicals can be leached into the deep soil. Second, fattening. In general, fertilizer or foliar spraying should be applied to the symptoms such as leaf spot, leaf margin scorching, plant yellowing and so on.

Beware of the three major drug hazards of cotton
Diagnosis and identification of insecticidal and fungicides. The damage degree of insecticides and fungicides is not only related to cotton variety, development stage and morphological characteristics, but also different from each other. For example, if dichlorvos is highly vaporized, cotton leaves can be smoked by spraying twice with 1000 times liquid; after being damaged by stone-sulfur mixture, the leaves and boll shells of cotton plants will produce burnt patches, and the leaves will soon dry off; stone-sulfur mixture is a strong alkaline agent, Bordeaux solution can only be used 7 ~ 10 days after use, if Bordeaux liquid is sprayed.

Technology of sowing whole Seedling of Cotton covered with plastic Film
Baicheng City, located in the west of Jilin Province, belongs to the continental monsoon climate. The contradiction between the long growth period of cotton and the shortage of heat resources needs to be solved in planting cotton. In order to achieve a bumper cotton harvest, we must first sow and take the whole seedling. In order to make efforts on adequate moisture, superior seed, fine sowing, film protection and healthy seedlings in production, we must do a good job in the "five passes". First, soil preparation and fertilization pass 1. Choose soil: cotton is a temperature-loving crop. It is better to choose Pinggang sandy (soil) land for planting, and the previous crop is better than Gramineae crops, bean stubble and so on.

The whole Seedling technique of Cotton in one sowing
The whole seedling technology of cotton sowing in one sowing has been a technical problem concerned by our cotton farmers and technicians over the years. Many factors are involved, such as soil temperature, soil moisture, sowing method, seed quality and treatment, etc., which are the key factors that affect the whole seedling. Therefore, we discuss with the majority of cotton farmers on how to realize the whole seedling and strong seedling early development of cotton. First, the preparation before broadcasting. Preparation for sowing is the premise and basis of sowing the whole plant. as the saying goes, "before the soldiers move, the food and forage go first" and "conceive in October and give birth once" all illustrate the importance of preparation. Create soil moisture before sowing: by

Pest Control techniques of Cotton in sowing and Seedling stage
Cotton sowing and nursery stage is an important link in cotton production. According to the forecast of the municipal meteorological station, the precipitation in the spring of 2008 (from March to April) is slightly less, 2000mm 250mm in the Dabie Mountains and 240mm 290mm in other areas. The average temperature in spring is close to the normal year, the temperature changes greatly, the cold air is active frequently, and the cold weather in late spring may occur. It is more beneficial to the occurrence of cotton leaf mite and cotton thrips, because the temperature changes greatly, which is not conducive to the growth of cotton seedlings, reduces the resistance of cotton seedlings, and is also beneficial to cotton seedling disease.

Key points of sowing and Seedling raising techniques of Cotton
First, to prepare the seedbed as soon as possible, we should choose the disease-free land with leeward to the sun, high terrain, convenient drainage and irrigation and low groundwater level as the seedbed. Second, the application of sufficient seedling bed fertilizer should be based on organic fertilizer, and appropriate amount of phosphorus and potassium fertilizer should be added to achieve a scientific formula. If you use ternary compound fertilizer as seedling bed fertilizer, you must have an appropriate amount. When fertilizing, it is necessary to mix well so as to achieve the goal of fertilizing both soil and seedlings. At the same time, there should be little or no application of urea and ammonium bicarbonate, so as to prevent burning root and dead seedlings or overgrowing cotton seedlings, resulting in weakening disease resistance, underdeveloped roots and delayed seedling stage after transplanting.

Preparation work before cotton sowing
First, make preparations before the broadcast. Land preparation, direct seeding cotton field should be raked in time during the suitable moisture period to preserve soil moisture, so that the plough layer is virtual and solid. 1. Deep ploughing and soil preparation: the cultivated time of cotton field can be divided into winter ploughing and spring ploughing, and winter ploughing is better than spring ploughing. Winter ploughing is deeper, usually 20-30 cm. Spring ploughing should be appropriate shallow, generally 13-16 cm is appropriate; after ploughing to fine soil preparation, so that the upper and lower solid, loose soil quality, water storage to preserve soil moisture. 2. Applying sufficient base fertilizer: applying sufficient base fertilizer and improving soil fertility is the basis of high yield of cotton. The amount of base fertilizer should be based on yield, soil fertility and fertilizer.

Matters needing attention in advance of cotton sowing date
Is it possible to advance the sowing date of cotton? According to the practice of cotton sowing for many years, the lesson in this aspect is very profound. Indeed, using plastic film mulching to raise seedlings in a nutrition bowl, cotton seedlings can also be cultivated by sowing seeds in mid-late March and early April, and a large-scale demonstration has been made in production, but the result is that it is very difficult to manage and it is difficult to ensure that the whole seedling is strong. First, the cold wave is frequent in the first and middle of April, the temperature varies greatly, and the north wind patronizes many times, so it is difficult to grasp the cover of the seedbed film; second, if you encounter continuous overcast

Key points of cotton sowing technology
Cotton is still the main crop in agricultural production in Yaobei, and the cotton sown area is estimated to be 25-30 million mu in 2007. In recent years, cotton output has increased steadily, and economic benefits have been continuously improved. In 2006, the actual cotton area of the whole city was 26000 mu, the average seed cotton yield was 193kg (equivalent to 76.5kg lint per mu), the output value per mu was 1150 yuan, and the income per mu was about 1000 yuan after deducting the cost of agricultural production. In particular, after popularizing insect-resistant hybrid cotton, the cost of using pesticides in cotton fields continues to decline, which will affect the farmland environment.

Maintenance and storage of cotton seeders
During the use of agricultural machinery, the performance of parts will be reduced or lost due to natural and artificial factors. Therefore, the technical maintenance of agricultural machinery is extremely important, correct maintenance and storage can greatly improve the service life of agricultural machinery, avoid premature wear of parts, and keep the machinery in good technical condition. The author through this year's Shawan County 514 thousand mu machine cotton picking promotion, to do a good job of cotton planter maintenance and storage summarized some essentials, cotton planter maintenance is divided into three categories: maintenance before operation, maintenance during operation, maintenance after operation
