Embodiment 1

[0034]Example 1: The hemp fiber non-woven fabric produced by the Hemp Research Institute of the Chinese Academy of Agricultural Sciences is a degradable porous fiber membrane with a longitudinal wet tensile strength greater than 5 N / m. First, spray a layer of water mist on the fiber membrane, then spray 12 grams of powdered sodium polyacrylate per square meter, dry it with hot air, and cut it into a 58 cm long and 28 cm wide sheet, which becomes a film with a moisturizing agent attached. Seedling raising diaphragm for rice transplanter. This diaphragm is especially suitable for the cultivation of dry seedlings in sandy soil, and plays an important role in machine-transplanted rice seedlings in Hainan Island.

Embodiment 2

[0035] Embodiment 2: In the production process of the paddy rice transplanter seedling raising membrane attached with humectant in embodiment 1, when spraying powdery sodium polyacrylate, adding 0.05 gram content per square meter is 15% wettable powder paclobutrazol , after being dried by hot air, cut into 58 cm long and 28 cm wide sheets, it becomes a paddy rice transplanter seedling raising membrane attached with a moisturizing agent and a plant growth regulator. This membrane is especially suitable for the cultivation of machine-transplanted rice seedlings in the middle and late rice seasons in southern China, and can effectively control the steepness of seedlings.

Embodiment 3

[0036] Embodiment 3: adopt the hemp fiber non-woven fabric among the embodiment 1 as carrier, spray powdery sodium polyacrylate 6 grams per square meter under wet conditions, form one deck mucus very soon on the non-woven fabric, then evenly sprinkle each 5-10 grams per square meter of coated controlled-release urea that releases 50% of the time in 30°C water for no less than 15 days, after drying, cut into 58 cm long and 28 cm wide sheets, and become rice with controlled-release nitrogen fertilizer Seedling raising diaphragm for rice transplanter. This diaphragm is suitable for the cultivation of machine-transplanted rice seedlings in southern rice areas, and can effectively promote early growth of seedlings after transplanting, early tillering and row sealing. Changing the release rate of the coated controlled-release urea can make seedling-raising membranes suitable for different temperature conditions.

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...
