Problems solved by technology

However, the growth and development of cotton has obvious timeliness. October 23 is the frost solar term, and immature cotton before the frost festival cannot bring economic benefits. Therefore, the buds formed after August 15 are invalid buds. When the recovery time is not enough When compensating for the loss of early cotton buds, it will cause a reduction in yield and affect the quality of cotton fiber
Traditional cotton cultivation management only focuses on intertillage loosening and soil fertilization measures, and lacks management measures to promote the recovery of aboveground cotton plants, which is ineffective in reducing cotton yield loss

Embodiment 1

[0067] Experimental plot: Cotton field affected by hail on the coast of Lixue Village, Fengjia Town, Zhanhua County, Shandong Province. The planting density is 4,500 plants, and 4,000 plants after the disaster. The cotton variety is Lumianyan No. 37. There are 4.5 functional leaves remaining on the stem.

[0068] Circle the affected cotton fields into two experimental plots, each with 1 mu. Field No. 1 is the experimental area, and Field No. 2 is the control area.

[0069] Field No. 1 (experimental area) cultivation method:

[0070] (1): On the first day after the disaster, the restoration substance A was sprayed on the leaves; the spraying amount of the restoration substance A was 12L / mu, including 10g / L of urea, 3g / L of potassium dihydrogen phosphate, 50mg / L of abscisic acid, and 25 % Carbendazim wettable powder 4g / L and 16μg / L vitamin B12.

[0071] (2): loosen the soil on the 1st day after the disaster, topdress fertilizer B; fertilizer B comprises humic acid organic fer...

Embodiment 2

[0089] Test plot: Hail-stricken cotton field in Liuzhuang Village, Baimahu Town, Xiajin County, Dezhou City, Shandong Province. The cotton variety is K836. The continuous cropping cotton field has a planting density of 4,000 plants / mu. 2 functional leaves remain.

[0090] Circle the affected cotton fields into two test plots, each with 0.5 mu. Field No. 3 is the experimental area, and Field No. 4 is the control area.

[0091] No. 3 field (experimental area) cultivation method:

[0092] (1): On the first day after the disaster, the restoration substance A was sprayed on the leaves; the spraying amount of the restoration substance A was 15L / mu, including 8g / L of urea, 5g / L of potassium dihydrogen phosphate, 60mg / L of abscisic acid, and 25 % Carbendazim wettable powder 3g / L and 18μg / L vitamin B12.

[0093] (2): 2 days after the disaster, loosen the soil, topdress fertilizer B; fertilizer B includes humic acid organic fertilizer and nitrogen fertilizer, and the application rate...

Abstract

The invention discloses a cultivation method for alleviating hail disaster loss in the bud stage of cotton, belonging to the technical field of cotton planting, comprising the following aspects: S1: spraying repair substance A on the leaf surface on the first day after the disaster; S2: loosening the soil 1-3 days after the disaster, Topdressing fertilizer B on the root; S3: On the 7th day after the disaster, spray the restoration substance C on the leaves; S4: On the 14th day after the disaster, spray the restoration substance D on the leaves; S5: After the boll opening rate of cotton is ≥ 40%, spray the Leaf ripening agent. The invention achieves the following beneficial effects: (1) It promotes the rapid restoration of hail-affected cotton, and improves the chlorophyll content and photosynthetic ability of cotton leaves. (2) Increase the accumulation of cotton biomass, laying a foundation for increasing the number of bolls and increasing cotton yield. (3) In the process of defoliation and ripening, the cotton boll opening before the frost festival is realized, the proportion of invalid buds is reduced, and mechanized harvesting is realized. (4) Compared with the traditional management method, the biological yield of cotton in the present invention is increased by more than 6.10%, the yield of seed cotton is increased by more than 11.77%, and the economic benefit of cotton is increased by more than 11.77%.

Description

technical field [0001] The invention relates to the technical field of cotton planting, in particular to a cultivation method for alleviating hail disaster loss in the bud stage of cotton. Background technique [0002] Hail is one of the natural disasters often encountered in cotton planting. Concentrated hailstorms in northwest Shandong, northern Henan and southern Hebei often occur from April to July, with the most in June, when cotton is in the budding period. Mild hailstorms have little effect on the growth and development of cotton, while moderate and severe hailstorms will seriously damage cotton buds, stems, branches, and leaves, affecting the growth and development of cotton plants, the number of buds, and cotton before frost, and then reducing cotton production. yield and quality. Hailstorms in the cotton bud stage often lead to damage to the top center of the main stem or decapitation, leaving only 1 to 5 functional leaves. The more severe the disaster, the slowe...
