Seedling breeding diaphragm for rice transplanter

Abstract

The invention provides a diaphragm for breeding seedlings for a rice transplanter. The diaphragm comprises a porous fiber membrane with wet tensile of greater than 5 N / m; and super absorbent polymer, coating controlled-release fertilizer, plant growth regulator and microcapsule long-term pesticides are adhered on the porous fiber membrane. When the seedlings transplanted by the rice transplanter are bred, the diaphragm is arranged below nutritional soils in a seedling breeding tray, in this way, the wind forces of seedling roots is effectively enhanced, the optimal transplanting age is advanced, namely the seedlings can be transplanted at a sucking seedling stage, at the same time, the microenvironment of the transplanted seedlings is improved, thus the diaphragm is beneficial for high yield cultivation of seedlings transplanted by the rice transplanter. Furthermore, an acid conditioning agent, a seedling strengthening agent, a controlled-release herbicide and other materials for agriculture can also be added in the diaphragm according to requirements of different areas. According to tests, by adopting the diaphragm provided by the invention to breed seedlings, the seedlings are planted at a 2-leaf stage by the rice transplanter, the low position tillering is enhanced, the leaves grow early and the rows are enclosed early, thus the heading stage is advanced; and the diaphragm is an effective measure for the high yield cultivation of the seedlings transplanted by the rice transplanter.

Description

technical field [0001] The invention belongs to the technical field of crop planting, in particular to a seedling raising and cultivation technology of mechanized rice transplanting. technical background [0002] Mechanized rice transplanting has developed rapidly in recent years. From the classification of seedlings and the principle of separate transplanting, mechanical transplanting can be mainly divided into two methods: root-washing and large seedling transplanting and medium and small seedling transplanting with soil. Washing the roots and transplanting the large seedlings has not been used in large-scale production and application at home and abroad so far because the technology is not perfect enough. my country, Japan, South Korea and other countries have promoted in recent years mainly the transplanting method of high-density blanket-shaped small and medium-sized seedlings with soil. This method uses high-density trays to raise blanket-shaped seedlings, and has be...

AI Technical Summary

Problems solved by technology

[0005] 2. When the seedlings were 21 days old, the high-density plate cultivation mode caused the growth of indica hybrid rice seedlings to be severely inhibited

3.8-leaf machine-transplanted hybrid rice, compared with sparsely sown strong seedlings and manually transplanted, the field grows slowly and has poor stress resistance

However, with the existing technology, when the seedling age is shorter than 10 days, the root growth and coiling force cannot meet the standards required by the rice transplanter, and machine transplantation cannot be performed.
