Abstract

The invention discloses a cultivation method for improving blooming of cassava. The cultivation method for improving the blooming of the cassava comprises the steps of land selection, land preparation, variety selection, planting, field management, seedling control and dwarfing, blooming period regulation and control, flower protection and the like. According to the cultivation method for improving the blooming of the cassava, through artificial agronomic measures and a chemical regulation and control method, nutrient components of nitrogen, phosphorus and potassium of the cassava are regulated, overground part spindling is inhibited, and the cassava is promoted to be converted from vegetative growth to reproductive growth, so that the blooming of the cassava is promoted, and then cassava hybrid seeds are obtained in a natural pollination or artificial pollination mode. The cultivation method for improving the blooming of the cassava is high in practicability and good in controllability, the problem that the blooming is difficult in Guangxi cassava planting areas is effectively solved, and a basis is provided for development of new cassava variety breeding in the future.

Description

Technical field[0001]The present invention belongs to the field of crop cultivation, and in particular, the cultivation method of improving the flowering of cassava flowers.Background technique[0002]Cassava (Name: Manihot Esculenta Crantz) is a plants in the eager cocons, and is one of the three big potato crops in the world. It is a non-grain biological energy crop, not only the staple food of billions of people worldwide, but also produces starch and One of the processed fuel ethanol materials is mainly used for development and utilization such as food, feed and industrial alcohol, which has a very high economic value. Guangxi is the largest cassava planting area in the country, accounting for more than 60% of the country.[0003]At this stage, the cultivation variety of tapas in China is more singular, and the main cultivation varieties are cultivated in South China 205. Due to long-term planting, varieties have severely degraded and low yields have become the urgent problem to be ...
