High-yield planting method of simultaneously ripe five-spike ricinus communis

Abstract

The invention provides a high-yield planting method of simultaneously ripe five-spike ricinus communis, solving the problems of low acre yield, simultaneously ripe recovery failure, difficult mechanical harvesting and the like of the existing ricinus communis planting method. At first, organic fertilizer and ternary compound fertilizer are applied; next, seeds are sowed; when growing out three to four main leaves, each seedling is fixed; when each seedling grows out five to six main leaves, a terminal bud is removed, and five main leaves are kept; moreover, paclobutrazol is sprayed onto the seedlings; when four to five class-one branch spikes of each seedling grow out flower buds, the intertillage ditching is performed at the flowering stage; furthermore, topdressing carbamide and diammonium phosphate are applied; after seven to ten days since pollination on all class-one branches of the ricinus communis seedlings, a chemical solution formed by blending pidine, 83% of maleic hydrazide, washing powder and water is sprayed onto the ricinus communis seedlings; and finally, when 80% to 85% of fruit in the ricinus communis plant is in dark brown, the fruit can be picked and harvested. With the adoption of the planting method provided by the invention, the simultaneously ripe harvesting is realized; the acre yield, the grain weight and the oil ratio are improved; and the mechanical harvesting can be realized.

Description

technical field [0001] The invention belongs to the field of crop planting, and relates to a high-yield planting method of castor bean that promotes early maturation, one-time maturity and is suitable for mechanized harvesting, in particular a high-yield planting method of five-eared castor bean that is one-off mature. Background technique [0002] Castor is a crop with many uses and low requirements for planting conditions. Due to poor varieties, low yield, and backward planting technology in the past, the planting scale is not large. Generally, it is used on the corner land or on the slope of the dam or in front of the house. Crowds are squeezed behind houses, so the total output of castor in China is very low, resulting in a shortage of raw materials for castor processing, mainly relying on imports. [0003] The existing planted high-stalk castor varieties plant 600-800 plants per mu. The plants grow tall, generally 1.8-2.5 meters in height, with many secondary and tertia...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of low yield per mu in the existing castor planting method, inconsistencies in the maturity stages of branches at all levels, which lead to the inability to harvest at one time, and the difficulty in mechanical harvesting, etc., and to provide a high-yielding castor plant with one-time maturity planting method
