Problems solved by technology

In fact, some plant growth regulators with strong activity, such as triacontanol, CPPU, etc., can significantly improve the growth and stress resistance of crops ([16] Liu Desheng et al. Plant growth regulator triacontanol (TA) milk Effects of powder on rice yield [J]. Chinese Engineering Science, 2002, 4(11): 82-88; [17] Chen Jingxiang, Ye Xufeng, Zheng Zerong. Preliminary study on the physiological activity of triacontanol-promoting effect of rice seedling growth [J]. Plant Physiology Communications, 1981, (02); [18] Huang Jianchang et al. The protective effect of CPPU on papaya drought stress [J]. Fruit Tree Journal, 2003, 20(3): 211-213; [19] Fei Xueqian et al. Effects of different concentrations of CPPU on the growth and nutritional quality of Actinidia sinensis [J]. Journal of Agricultural and Environmental Sciences, 2005(24): 30-33), but the application on turfgrass is rarely reported
Most of the studies on the effects of mixed application of fertilizers and plant growth regulators on cold resistance focus on promoting high yields of grain crops, etc. ([20] Shi Hongzhi, Liang Fangzhi, Tang Jihua. Effects of spraying paclobutrazol and nitrogen, phosphorus, and potassium fertilizers on summer soybean production in summer soybean [J]. Journal of Henan Agricultural University, 1994, 28 (1): 37-40; [21] Fan Xiuzhen et al. Physiological effects of mixed triacontanol and potassium dihydrogen phosphate on rice [J]. Journal of Fujian Normal University ( Natural Science Edition), 2003, 19(4): 80-84), rarely reported on lawn

Embodiment 1

[0023] ① Preparation: For the preparation of component A, weigh 300 mg of paclobutrazol powder and dissolve it in 6 ml of acetone, then add 20 mg of triacontanol, stir to dissolve, and add water to 1000 ml; for the preparation of component B, weigh chitosan (Molecular weight: 100,000) 4000mg, add about 5ml of phosphoric acid co-solvent, mix well, add tap water to 1000ml; preparation of component C, soybean meal hydrolyzate 2000mg, urea 500mg, potassium magnesium sulfate fertilizer 1000mg, mix with tap water to 1000ml.

[0024]②Use: Mix the prepared components A, B and C in equal volumes, use a sprayer to spray the Manila lawn, and spray in mid-November with a spray volume of 667m 2 Foliar spray 80kg.

[0025] ③Effect: After the Manila grass is sprayed with this formula by the sprayer, it can obviously turn green within 10 days, and the greening time will last until mid-January. The greenness and growth of the lawn after spraying are significantly better than those without spra...

Embodiment 2

[0027] ① Preparation: For the preparation of component A, weigh 600 mg of paclobutrazol powder and dissolve it in 8 ml of acetone, then add 100 mg of triacontanol, stir to dissolve, and add water to 1000 ml; for the preparation of component B, weigh chitosan (Molecular weight 250,000) 6000mg, add about 10ml of phosphoric acid co-solvent, mix well, add tap water to 1000ml, store for 5 days; preparation of component C, soybean meal hydrolyzate 2000mg, urea 800mg, potassium magnesium sulfate fertilizer 800mg, mix tap water to 1000ml.

[0028] ②Use: Mix the prepared components A, B and C in equal volumes, use a sprayer to spray the Manila lawn, and spray in mid-November with a spray volume of 667m 2 Foliar spray 60kg.

[0029] ③Effect: Manila grass can obviously turn green within 12 days after spraying this formula with a sprayer, and the greening time and comprehensive quality of the lawn are equivalent to the treatment in Example 1.

Embodiment 3

[0031] ① Preparation: For the preparation of component A, weigh 300 mg of paclobutrazol powder and dissolve it in 8 ml of acetone, then add 200 mg of triacontanol, stir to dissolve, and add water to 1000 ml; the preparation of component B is the same as in Example 2; The preparation of component C, soybean meal hydrolyzate 2000mg, urea 500mg, potassium magnesium sulfate fertilizer 500mg, mixed with tap water to 1000ml.

[0032] ②Use: Mix the prepared A, B and C components in equal volumes, use a sprayer to spray the turf lawn, and spray in mid-November, with a spray volume of 667m 2 Foliar spray 60kg.

[0033] ③Effect: After spraying this formula with a sprayer, the turf lawn can obviously turn green in 12 days. The comprehensive quality of turf (growth, resistance and greenness) was significantly better than that of the control.

Abstract

A warm-season lawn grass winter green-maintaining growth-promoting agent and a method for making the same relate to a plant green-maintaining growth-promoting agent, providing a warm-season lawn grass winter green-maintaining growth-promoting agent capable of increasing chlorophyll content and overground biomass, reinforcing cold resistance and prolonging green period and a method for making the same. The growth-promoting agent comprises an A component, a B component and a C component, wherein the A component is a paclobutrazol triacontanol aqueous solution containing a latent solvent; the B component is a chitosan acidic aqueous solution; and the C component is proteolysis product quick-acting fertilizer. The method is as follows: paclobutrazol powder is dissolved in the latent solvent, and triacontanol and water are added so as to obtain the A component; chitosan and water are added in an acidic latent solvent, thereby obtaining the B component; and proteolysis product is dissolved by water, and then urea, potash magnesium sulphate fertilizer and water are added so as to obtain the C component.

Description

technical field [0001] The invention relates to a plant greening and growth promoting agent, in particular to a warm-season turfgrass winter greening and growth promoting agent and a preparation method thereof. Background technique [0002] The low temperature in winter and human trampling can easily cause chlorosis and growth stagnation of warm-season turfgrass, seriously affecting the quality and landscape of urban turfgrass. Breeding is the best way to solve warm-season turfgrass yellowing in winter ([1]Xu Xiaogang, Wu Yanqi. Discussion on the causes and countermeasures of warm-season turfgrass winter yellowing[J]. Grass Industry Science, 2000, 17(2): 430- 49), but there are not many successful examples ([2] Li Xi et al. Research progress on cold resistance of warm-season turfgrasses [J]. China Grassland, 2000, (4): 53-58). Measures such as fertilization and spraying growth regulators can achieve good results ([3] Sun Xiaoxia, Lin Wenxiong Measures to improve the quality...
