Embodiment 1

[0043] Embodiment 1 chemical control IV preparation:

[0044] Chemical control IV is a uniform mixed solution composed of the following components and proportions:

[0045] Ethephon (CEDP): Gibberellin (GA3): Brassinolide (BR): Absolute Ethanol: Calcium Dodecyl Sulfonate: Tween 80: KH 2 PO 4 : CaCl 2 :H 3 BO 3 : fulvic acid: dimethyl sulfoxide: water is 20: 1.5: 0.01: 200: 30: 30: 125: 250: 80: 50: 10: 700; the dimensions involved in the ratio of absolute ethanol is the volume ml, and the dimension involved in the proportioning of the rest of the materials is the mass g.

[0046] Group A solution: according to chemical control IV composition ratio, weigh ethephon (CEDP), gibberellin (GA 3 ), brassinolide (BR), are dissolved in the dehydrated alcohol of proportioning quantity successively, then add the calcium dodecylsulfonate of proportioning quantity, Tween 80, stir;

[0047] Group B solution: take by weighing the potassium dihydrogen phosphate (KH 2 PO 4 ), calcium ...

Embodiment 2

[0048] Application experiment and effect of embodiment 2 chemical control IV

[0049] In this experiment, the effect of chemical control IV on the yield and quality of sugar beet was evaluated. The field test was conducted at the Taonan Sugar Beet Breeding Research Institute in Jilin Province. The soil tested had a salt content of 0.45%, a pH value of 8.6, and medium fertility. The variety tested: HYB74.

[0050] 1. Test method

[0051] The experiment consisted of 4 treatments:

[0052] (1) Chemical control IV: Spray chemical control IV on the leaf surface on August 25, use the uniform mixed solution of chemical control IV mixed with water 50 times to spray on the sugar beet leaf surface with a sprayer, and the area of ​​each plot is 19.2m 2 , spray 1.2kg.

[0053] (2) Sugar enhancer No. 1 (MH): Spray the concentration of MH mixed with 1000 times of water on the beet leaves with a daily sprayer, and the area of ​​each plot is 19.2m 2 , spray 1.2kg.

[0054] (3) Sugar-enh...

Abstract

The invention relates to a composite growth regulator for increasing yield and saccharinity during the sugar accumulating period of beetroot and a usage, which are particularly suitable for the application under the arid environment, and have obvious effect on increasing yield and saccharinity through the foliage spray in late August. The regulator can not only control the injury caused by the stress of the environment, and keep the duration of the function foliage at the maximum, but also increase the activity of sucrose synthase, reduce the consumption of glycogen, promote coordination and uniform of the beetroot and the environment, individual and group, root and overground part, the external shape of the plant and internal physiological function during the sugar accumulating period, and finally reach the goal of improving the yield and saccharinity. Under the environment of the west of Jilin province, with less than 300 mm of the amount of precipitation, 0.47 percent of salt content and PH value of 8.6, the yield of beetroot reaches to 52,766.25kg/hm2, the yield is increased by 12.18 percent, and the sugar content is 17.0 percent, which is increased by 1.4 percent.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a stress-resistant, yield-increasing, sugar-increasing compound growth regulator for the sugar beet accumulation period and its usage. Background technique [0002] Sugar beet is not only a sugar raw material, but also an important raw material for the production of ethanol. China's beet planting areas are mainly distributed in the "Three North" regions. Due to the impact of salinity, drought and the spread of diseases, the yield and sugar content of beet are decreasing year by year. Especially in September, sugar beet is under extreme drought stress, and this time is the main period of sugar beet accumulation. Drought stress causes premature senescence of functional leaves and seriously affects the transport and accumulation of photosynthetic products (mainly sucrose) to roots. One of the most effective and feasible technical measures to solve this problem is...
