Method for seed selecting and remaining of double-cropping water bamboos in summer

Abstract

The invention relates to a method for seed selecting and remaining of double-cropping water bamboos in summer. According to the method, at the terminal stage of or after harvest of the water bamboos growing in summer, robust stem tillers in a normal harvest area are selected, piled up under dark conditions after slightly processed, and watered to maintain humidity. Five days later, when the water bamboos can be transplanted into water bamboo fields for autumn, stem tillers without sprouting young leaves are rejected, and stem tillers with young leaves longer than 5cm are transplanted into the large fields. Not only is the output of the water bamboos growing in summer not affected, but also temporary planting in other fields is unnecessary. The selected and remained stem tillers are large in specifications and nutrient amount, and beneficial to sprouting and rapid growth of new-sprouting branch tillers and ensures relatively large output of water bamboos in autumn. Residual stem tillers in water bamboo fields for summer are fully utilized for promoting the use efficiency.

Description

technical field [0001] The invention relates to a summer seed selection and retention method of double-crop wild rice stems. It belongs to the technical field of agricultural (vegetable) cultivation. Background technique [0002] Liu Yiman et al. (2010) reviewed the summer seed selection and retention techniques for double-cropping Zizania zizania based on previous data: (1) Practice in Wuhan, Hubei: the selection time is mid-to-late May to June. The seed selection criteria are plants with early, abundant and homogeneous summer water junctions, low cross junctions and typical varietal characteristics. The selection objects are tillers that occur in spring and summer but are not fertile. Pull out the selected tillers individually from the base, and plant them in a special seedling field with a row spacing of 20 cm and a plant spacing of 15 cm. Before artificial planting, cut off the upper part of the leaves of the selected tillering seedlings, leaving 25-35 cm at the base. ...

AI Technical Summary

Problems solved by technology

The method of selecting and retaining smaller tillering seedlings, because of less nutrient accumulation, the yield of autumn rice is low, and even in order to obtain a high yield of summer rice in the next year, autumn rice is not harvested in the same year; Opening up another field for planting reduces the utilization rate of the land, and under the current situation of shortage of cultivated land, it is difficult to implement in many places

Moreover, after the harvesting of summer jiaozi is completed, there are still a large number of unpregnant jiaozi remaining in the field, and some stems and tillers that are pregnant but have not yet reached the harvesting standard; Prepare to plant the next crop, resulting in a lot of wasted stems and tillers
