Problems solved by technology

This method requires high germination temperature control, it is difficult to ensure the uniformity of centralized germination, a certain amount of germination facilities is required, and the damage of rice buds reaches 5-10%, resulting in a relatively high cost and a decline in the utilization rate of rice seeds.
Machine transplanting has very high requirements on the uniformity of seedling growth, packing soil and easy separation of seedlings. It is difficult for existing seedling raising methods to meet the demands of transplanting in terms of uniformity of seedling growth, ability of packing soil and easy separation of seedlings. The operating requirements of the machine, the seedling rate after machine transplanting is less than 90%

Embodiment Construction

[0015] Technical thinking of the present invention:

[0016] Select fresh vermicompost sieved with 20 meshes and mix it evenly with 20 meshes sieved soil of Daejeon soil according to the ratio of 1:1 as the cultivation substrate for machine-transplanted seedlings, put the substrates into seedling trays through the machine assembly line or manually, and then put the rice soaked for 48 hours. Seeds are sown by machine or artificially evenly, covered with 20-mesh sieved fine soil with a thickness of 0.5cm, and then the seedling trays after sowing are moved indoors and piled up to a height of 1-1.5m. After more than 80% of the buds in the seedling tray are unearthed, the seedling tray is transplanted to the outdoor seedling field to grow until the three leaves are one heart.

[0017] The main methods and steps of implementation:

[0018] Substrate preparation - sowing - stacking germination - seedling cultivation

[0019] Matrix preparation:

[0020] The fresh vermicompost was ...

Abstract

The invention relates to a method of raising machine-transplanted seedlings. According to the method, earthworm cast and earth are used as seedling culture medium; rice seeds are exposed to sunshine and then soaked in moving clear water; seedling trays are fully loaded with the medium and fully irrigated by means of mist; the seeds are evenly sowed in the seedling trays and covered with fine earth; germination piles are obtained by piling and subjected to centralized accelerating germination; the germination piles are tightly wrapped with plastic film to increase the interior temperature of the film; when 80% seedlings emerge in the seedling trays, the seedlings are transplanted to raise in outdoor seedling fields. The method has the advantages that the defects that the existing seedling raising method hardly meets the operation requirements of rice transplanters in terms of seedling growth regularity, root-climbing earth carrying capacity and seedling division easiness and machine-transplanted seedlings are not higher than 90% in emergence rate are overcome; the seedlings raised by the method are strong with well-developed roots and more than 90% of white roots, the roots are highly active, seed availability is increased by 10%, seedling regularity is increased by 15%, emergence rate is increased by 10%, and yield can be increased by about 10%.

Description

technical field [0001] The invention relates to crop cultivation technology, in particular to a method for machine-transplanted seedlings. Background technique [0002] The existing rice transplanting and seedling raising methods are divided into industrialization and field seedling raising, and the seeds are sown after soaking and accelerating germination. In this method, there are high requirements for germination temperature control, it is difficult to ensure the uniformity of centralized germination, a certain amount of germination facilities is required, and the damage of rice buds reaches 5-10%, resulting in a relatively high cost and a decline in the utilization rate of rice seeds. Machine transplanting has very high requirements on the uniformity of seedling growth, packing soil and easy separation of seedlings. It is difficult for existing seedling raising methods to meet the demands of transplanting in terms of uniformity of seedling growth, ability of packing soil...
