Examples of the experiments
Material method
Demonstration site: 1 connecting 31 st team of No. 2 scholars of Xinjiang production and construction;
demonstration area: 780 mu of land;
demonstration time: 4 months in 2018-10 months in 2018;
the demonstration variety is as follows: handan Hetero646;
demonstration of fertilizer application: the invention relates to a nutritional formula.
Design of experiments
And (3) applying no base fertilizer in the topping-free area, and adopting the topping-free accurate fertilizer and water management scheme in the table 1 in the whole process. Other pest and disease damage management and field farming operation are finely managed according to the high-yield cotton field standard. The specific fertilization protocol and the comparative fertilization protocol (conventional fertilizer and water management protocol) are detailed in table 2.
TABLE 2 topping-free accurate fertilizer and water scheme and traditional fertilizer and water management scheme
Analysis of results
(1) Influence of different fertilizer and water management schemes on cotton plant height
As can be seen from FIG. 1, the plant height of the cotton in the demonstration area is steadily increased according to the established growth speed on the basis of accurate fertilization 110 days after field planting, and the plant height is always controlled within the established plant height model. And (3) the plant height of the cotton adopting the topping-free scheme is basically maintained at about 96cm 110 days after the field planting, and the plant height is not increased any more. This height is a suitable mechanical harvesting height.
(2) Effect of different fertilizer and water management schemes on cotton boll number
As can be seen from FIG. 2, the cotton bud number in the non-topping cotton demonstration area is slowly increased in the early stages of the bud period and the boll period, and the bud number enters the rapid increase stage 90 days after planting. The flower and boll number of the topping-free accurate fertilizer and water management scheme is higher than that of the traditional fertilizer and water manual topping scheme after 60 days of field planting, the flower and boll number of the cotton plant of the accurate fertilizer and water management scheme reaches the maximum value in 100 days after field planting, the traditional fertilizer and water scheme is 10 days later than the topping-free scheme when entering the maximum boll period, and the maximum value of the flower and boll number is 3.9 less than that of the accurate fertilizer and water management scheme. After the boll stage, due to the influence of dry hot air, cotton plants enter a bud removing and bud dropping stage, and finally, in the later stage of the boll stage (130 days after planting), the number of the cotton bolls in the precise fertilizer and water management scheme is stabilized to be about 17, and the number of the cotton bolls in the traditional scheme is stabilized to be 13.4, which is 3.6 less than that in the precise fertilizer and water scheme.
(3) Influence of different fertilizer and water management schemes on growth point and plant type at top end of cotton
From fig. 3a, it can be seen that the cotton side branch which is manually topped is re-sprouted, topping is required again, and the boll-forming part is moved upwards. The precise fertilizer and water management leads the growing point of the cotton to automatically necrose, and the growing point does not continue to grow (fig. 3b and c).
The cotton plant type of the topping-free precise fertilizer and water management scheme is tower-shaped, the manual topping is inverted triangle-shaped, the boll-forming part moves upwards, and the number of bolls is obviously less than that of the precise fertilizer and water management scheme (fig. 3a and d).
(4) Influence of different fertilizer and water management schemes on cotton yield constituent elements and quality
As can be seen from the results in the following Table (Table 3), the number of cotton bolls per plant using the precision fertilizer and water management protocol was 17, and the number of cotton bolls per plant using the conventional control protocol was 13.4; the number of cotton bolls in the precise fertilizer and water management scheme is 4.2, which is 0.8 more than that of 3.4 cotton bolls in the comparison scheme, and meanwhile, the weight of cotton bolls is about 15g than that of the comparison scheme; meanwhile, the quality of the cotton is greatly improved, the clothing is 2% lower than the contrast, the velvet length is 1.3mm longer than the contrast, and the grade of the cotton reaches the second-level cotton standard.
TABLE 3 influence of different fertilizer and water management schemes on cotton yield constituents and quality
(5) Cotton yield difference and economic benefit analysis under different fertilizer and water management conditions
As can be seen from the following table (Table 4), the cotton yield in the test area is increased by 88kg per mu compared with the traditional cotton, and meanwhile, the yield is increased by 572 yuan per mu. Deducting the increased 8 yuan per mu of cotton in the test area, the net benefit of the cotton in the test area is increased by 564 yuan per mu compared with the traditional cotton. The cotton yield in the test area is increased by 0.37 compared with the traditional cotton.

Conclusion
The topping-free precision fertilization scheme can realize the topping-free of the cotton through the plant type control and the regulation and control of vegetative growth and reproductive growth of the cotton. And on the basis of avoiding manual topping, the goals of increasing the yield and increasing the efficiency of cotton are realized. Meanwhile, the input amount of the chemical fertilizer per mu of the precise fertilizer and water management scheme is 50kg, compared with the traditional fertilizer consumption of 81.5kg, the topping-free precise fertilizer and water management scheme greatly reduces the input amount of the fertilizer, improves the utilization efficiency of the fertilizer, reduces agricultural non-point source pollution and resource waste, and realizes the green and sustainable development of Xinjiang cotton.
