Description
Technical Field
The invention relates to a special controlled-release fertilizer, in particular to a disease-preventing special controlled-release fertilizer for Xinjiang cotton, and a preparation method and application thereof, belonging to the technical field of production and application of controlled-release fertilizers.
Background
As an important commodity cotton base in China, the total output of Xinjiang cotton accounts for about 40% of the whole country, and in 2010, the planting area of the Xinjiang cotton is 1420 mu, and the total output is 150 million tons. Xinjiang has been the first place in China for 15 years continuously for 7 indexes of planting area, total yield, average yield per mu and the like.
In recent years, the popularization of transgenic insect-resistant cotton effectively controls the harm of pests such as cotton bollworms and the like. However, the transgenic cotton has poor resistance to diseases such as rhizoctonia rot and fusarium wilt. In recent years, the incidence of disease in Xinjiang area increases year by year due to the extension of the continuous cropping years of cotton area, the incidence of disease in rainy and low-temperature years can reach 100%, the seedling death rate is more than 20%, and the great loss is caused to the cotton peanut yield. The cotton rhizoctonia disease and wilt disease belong to soil-borne diseases, and the infection of cotton is mainly in seedling stage. The occurrence of cotton diseases also has great relation with soil nutrient balance and fertilization management, and the fertilizer is reasonable, has developed root system, robust plants and strong disease resistance. Therefore, the effect is better through nutrition regulation according to the nutrient condition of the soil and prevention by certain medicines. The controlled release fertilizer has the advantage of not harming seeds and root systems, and if the disease prevention medicament and the controlled release fertilizer are matched with each other and are directly applied around the root systems during cotton sowing, infection can be better prevented, and the occurrence probability of diseases is reduced.
CN 100429192C (200710114007.6) discloses a special controlled release fertilizer for cotton and a manufacturing method thereof, and 6 percent and 7 percent of thermoplastic resin coated urea, sulfur coated urea, potassium chloride compound fertilizer, potassium chloride, zinc sulfate and borax are precisely compounded according to the fertilizer requirement rule of cotton to form the special formula controlled release fertilizer for cotton. Patent document CN101891550A (201010236133.0) discloses a synchronous nutrient controlled release fertilizer special for cotton and application thereof, wherein the fertilizer is prepared by compounding humic acid coated controlled release fertilizer, sulfur high molecular polymer coated controlled release fertilizer, thermoplastic and thermosetting double-layer coated urea, zinc sulfate and boric acid as raw materials. The release rule of the nutrients of the two special controlled-release fertilizers for cotton is consistent with the absorption rule of cotton on the nutrients, and the two special controlled-release fertilizers for cotton are intensively applied into the planting furrows at one time during cotton sowing or transplanting, so that additional manuring is not needed, the root system is not damaged, and the utilization rate of the fertilizer is high. But they have disadvantages in that: firstly, the nutrient proportion is designed only aiming at nutrient absorption of cotton, and the difference of soil nutrients in different areas is not considered; secondly, it has no disease preventing effect.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a special controlled release fertilizer for Xinjiang cotton for preventing and treating diseases and a preparation method thereof. The invention provides an application method of the special controlled release fertilizer for cotton.
Summary of The Invention

According to the invention, the application of the special controlled release fertilizer for cotton is used for cotton planting in Xinjiang area, and can prevent and control cotton rhizoctonia rot, epidemic disease, anthracnose, blight and the like while providing nutrients in the cotton growth period.
The application of the special controlled release fertilizer for cotton is characterized in that the fertilizing method comprises the following steps:
i. when seedling is raised in the nutrition pot, before transplanting and field planting, fertilizer is applied in the field planting ditch, and the fertilizer application depth is 5-6 cm below the bottom of the ditch; or,
and ii, when the cotton is directly sowed, fertilizing and sowing are carried out simultaneously, the fertilizer rows and the sowing rows are on the same line, and the depth of the fertilizer in the sowing trench is 12-15 cm from the ground, or 5-8 cm below the seeds.
According to the fertilizing method, the fertilizing amount of the special controlled-release fertilizer for cotton is as follows: the total nutrient of nitrogen, phosphorus and potassium is converted, and the dosage per mu is 20 kg-30 kg; or taking the amount of ordinary fertilizer nutrients applied by local farmers as reference, and applying the fertilizer according to 70-80 wt% of the amount of ordinary fertilizer nutrients such as nitrogen, phosphorus and potassium.
The invention has the following excellent effects:
1. the nutrient proportion is suitable for the soil nutrient condition of Xinjiang cotton producing area
The soil in Xinjiang area is mainly aeolian sandy soil, the content of calcium carbonate is high, the pH value is high, the effectiveness of nutrient elements such as phosphorus and zinc is easily reduced, meanwhile, the weathering effect of the soil is weak, the leaching of basic ions is less, the effective potassium content of the soil is high, and the conditions can be used as references for the design of a fertilizer formula. The disease-proof controlled release fertilizer special for Xinjiang cotton is prepared according to the soil nutrient characteristics of Xinjiang region accurately, and can meet the high-yield requirement of cotton.
2. The nutrient release period is suitable for the absorption requirement of Xinjiang cotton
The nutrient release period and the release rate of the controlled release fertilizer in soil depend on the soil temperature and moisture conditions, compared with cotton planting areas in Henan, Hubei and the like in China, the controlled release fertilizer in Xinjiang has low temperature, less rainfall, relatively less soil temperature and moisture content, the controlled release fertilizer in the same release period is suitable in the middle east area in China, while the release period is prolonged in Xinjiang areas, and the nutrient is incompletely released in the cotton growth period, so that the cotton growth is influenced, and the fertilizer utilization rate is reduced. The special controlled release fertilizer for cotton is designed and compounded according to the soil temperature and water conditions of cotton production areas in Xinjiang, and the nutrient release period and the release rate are suitable for the absorption requirements of Xinjiang cotton.
3. Good disease prevention effect
Due to the extension of the continuous cropping years of Xinjiang cotton, the disease is more and more serious day by day, especially in the seedling stage. The conventional method in production is to use liquid medicine to irrigate roots or spray the liquid medicine when the disease occurs, but certain harm is caused. The medicament in the disease-proof controlled-release fertilizer special for Xinjiang cotton selects various medicaments with better effect on preventing and controlling cotton diseases, and is directly applied to the main root area of cotton together with the fertilizer, thereby having good effect on preventing germs from invading the root system and damaging seedlings.
4. Once application, double effects, labor saving and labor saving
According to the conventional method, root irrigation or pesticide spraying is carried out for 2-3 times every time when the cotton is subjected to diseases, so that more labor is used, and the labor intensity is high. The special fertilizer is directly applied with the fertilizer at one time, reduces the operation times, greatly reduces the labor intensity of farmers, saves the labor cost and improves the economic benefit.
