Abstract

The invention discloses a method for preparing rooting-free stem nourishing solution for sugarcane hybrid seed production. The method includes steps: (1) mixed acid solution preparation, to be specific, slowly adding concentrated sulfuric acid into 1L of water, continuously stirring, sequentially and proportionally adding nitric acid and phosphorous acid after the temperature of the solution is reduced to the room temperature, finally adding water until the volume reaches 2L, and well stirring to keep for standby application; (2) intermediate liquid preparation, to be specific, adding 150ml ofmixed acid solution prepared in the step (1) into 2.5L of water to dilute, well stirring, feeding sulfur dioxide gas to increase the weight of the solution by 165mg, and making the solution to be 3L;(3) stem nourishing solution preparation, to be specific, adding 200ml of the intermediate liquid prepared in the step (2) into 18L of water, and well mixing to obtain the stem nourishing solution. By soaking of non-rooted ear stems in the rooting-free stem nourishing solution for sugarcane hybrid seed production, functions of sugarcane stem rotting prevention, bacterium inhibition and keeping ofsmoothness of sugarcane stem dredging tissues are achieved, moisture and nutrient demands of the ear stems in a hybridization process are met, and the sugarcane stems can survive for 70 days or longer.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a preparation method of a root-free and stem-raising solution for sugarcane hybrid seed production. Background technique [0002] Sugarcane is an important sugar crop and the main raw material for sugar production in the world today. Sucrose accounts for about 70% of the world's total sugar and is the main source of sugar in my country. my country's sugarcane planting area accounts for more than 85% of the national sugar crop planting area, and sugar production accounts for more than 92% of the total sugar. Guangxi is the largest sugarcane production base and sugar production center in my country. The sugarcane planting area and sugar production both exceed 60% of the national total, ranking first in the country all year round. The cane sugar industry is one of the pillar industries in Guangxi, and it is an advantageous leading industry to promote agricultural development,...
