Problems solved by technology

[0003] Due to the special structure of the spring Amomum flower organ, that is, the stigma is higher than the anther, resulting in a low rate of natural pollination and fruit setting, resulting in a very low natural growth and yield of Spring Amomum, which affects the economic benefits of large-scale planting. Insect pollination and artificial pollination are usually used, but relying on insect pollination is affected by the climate, and the spikes of Amomum chinensis grow on the rhizomes on the ground, resulting in many restrictions on insect pollination, which directly affects the yield of Amomum sativa

Abstract

The invention discloses a pollination method for increasing the yield of spring Amomum, and the pollination method for increasing the yield of Amomum comprises the following steps: 1. field management before pollination, 2. collecting pollen, 3. manual pollination, 4. pollination after pollination manage. Beneficial effects: artificially pollinate the spring amomum by combining pollination at the flowering stage and pollination at the bud stage, using repeated spot pollination to increase the probability of successful pollination, and remove pollen-free or dense female plants and male plants in time , to improve the fruit setting rate of Amomum sativa, and supplement nitrogen, phosphorus and potassium fertilizers in time to ensure the nutrients needed for the growth of Amomum sativa fruit, thereby increasing the output of Amomum sativa.

Description
