Embodiment Construction
[0016] The method for using the sugarcane drought-resisting agent provided by the present invention is as follows: take out the five-sided hard plastic packaging box containing the sugarcane drought-resisting agent, stick the incision surface of the cut sugarcane stem close to the drought-resisting agent, and slide firmly to complete the sugarcane stem incision The anti-drought treatment work at one end of the sugarcane stem, and the other end of the incision surface of the sugarcane stem is treated in reverse, which not only completes the drought resistance treatment of the sugarcane stem, but also completes the drought resistance treatment of the incision surface of multiple sections of sugarcane stem at one time, and within one packaging unit The sugarcane drought-resistance agent is designed to be the treatment dosage of the planting amount of one mu of sugarcane stems.
[0017] The implementation results of the technical solutions of the present invention will be described...

The invention provides a drought-resisting agent for sugarcane and a preparation method thereof. The drought-resisting agent for sugarcane is prepared from the following raw materials in percentage by weight: 90-92% of hydrocarbon substance, 4-8% of 50% carbendazol wettable powder, 0.5-4.5% of potassium sulfate and 0.1-0.5% of gibberellin and a gibberellin activity protectant, wherein the gibberellin and the gibberellin activity protectant is blended in a weight ratio of 1:(3-3.5). The method comprises the following steps: firstly, heating and dissolving the hydrocarbon substance; when the temperature is reduced to 60-80 DEG C, evenly mixing the 50% carbendazol wettable powder and the potassium sulfate into the dissolved hydrocarbon substance; and evenly adding the mixture of the gibberellin and the gibberellin activity protectant so as to obtain the drought-resisting agent composition for sugarcane. Before a sugarcane ratoon is planted, the drought-resisting agent for sugarcane is used for sealing fresh incisions at the two ends of the sugarcane ratoon. The drought-resisting agent for sugarcane provided by the invention can effectively reduce the moisture evaporation loss of the sugarcane ratoon, significantly enhance the adaptability of the sugarcane ratoon to water deficit and increase the emergence rate of newly planted sugarcane, therefore, the drought-resisting agent forsugarcane has a broad application prospect in the aspects of improving the yield of sugarcane planted in dry lands and hilly lands.
Description
Technical field: [0001] The invention relates to the technical field of plant growth regulators, in particular to a sugarcane drought-resistant agent and a preparation method thereof. Background technique: [0002] Sugarcane is an important sugar crop in my country, with a long growth cycle and high water demand. my country's sugarcane is mainly distributed in Guangxi, Yunnan, Guangdong, Hainan and other provinces, of which dryland sugarcane accounts for more than 80%, which belongs to the typical "rainfed" agriculture. Due to the frequent drought in winter and spring, it poses a serious threat to the emergence of sugarcane planting in dry land every year. In order to solve this problem, while adopting the comprehensive cultivation technology of sugarcane drought resistance, it is necessary to seek new technical approaches. [0003] According to analysis, the water content of the sugarcane seed stem itself is more than 70%, and its seed coat is composed of fiber and wax, wh...
