Potato seed facility seedling raising method

Abstract

The invention discloses a potato seed facility seedling raising method. The method includes: using a rectangular shallow water containing pool subjected to waterproof treatment as a seedling raising pool; using solid framework materials with high plasticity to build a seedling raising shed frame, and mulching a film on the shed frame to build a seedling raising shed; selecting a rectangular seedling raising plate with a plurality of seedling raising cavities; making a culture medium suitable for sprouting and growth of potato seeds; preparing solid fluid fertilizers according to a certain proportion of microelements and major elements of crop nutrients; filling the culture medium in the seedling cavities of the seedling raising plate, and placing the seedling raising plate with the seeds sowed in the seedling raising shed pool; and manually or automatically controlling the temperature and humidity to meet grouting and seedling of the seeds, adding the seedling raising fertilizers into the seedling raising pool according to a certain nutrition concentration, controlling diseases, insect pests and weeds, and transplanting seedlings to a mesh room or fields after seedling exercising. The method is high in emergence rate, the seedlings are developed in root system, the transplanting survival rate is high, seedling nursery management operations are simple, seedling raising cost is low, and seedling raising efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of seedling raising of potato seeds, and in particular relates to a method for raising seedlings of potato seeds in facilities. Background technique [0002] The technical scheme that prior art provides is: [0003] Build the nursery pool: apply cement mortar or pad the inside of the pool to prevent water leakage. After the nursery pool is built, fill the pool with water. [0004] Floating seedling trays for culture medium: Use foam plastic or polystyrene plastic trays as seedling trays, with inverted pyramid-shaped seedling holes with small holes at the bottom evenly distributed on it, and the spacing between adjacent seedling holes is 0.5cm. Both are filled with pre-soaked culture medium, which is made by mixing perlite and humus in a weight ratio of 1:8-10. [0005] Sowing virus-free test-tube micro-tubers: Sow the germinated virus-free test-tube micro-tubers in the seedling holes on the seedling trays ...

AI Technical Summary

Problems solved by technology

[0010] The invention provides a method for facility seedling cultivation of potato seedlings, aimed at solving the problem that existing potato seedlings are cultivated and mostly adopt small sheds for seedling cultivation. Although seed soaking for germination or 100mg / L gibberellin soaking is used before sowing, the emergence rate is between About 70%, and the root system is underdeveloped, the nursery management work is heavy, the emergence rate is low, the breeding process is slow, the cost of seedling raising is high, and the problem of small population size can be selected
