AI Technical Summary

Problems solved by technology

Although the nutrient liquid film technology can solve the problems of soil compaction and fertilizer leaching, in the practical application of the modern nutrient liquid film technology, its production facilities are relatively complicated and the cost is high, and it is difficult to meet the needs of large-scale agricultural production.

Embodiment 1

[0036] A seedling raising method adopting an intermittent flow type nutrient liquid film, which specifically carries out the seedling raising process for tobacco seedlings according to the following steps:

[0037] (1) Using segmented seedling cultivation:

[0038] Tobacco seedlings at the cross stage were bred in a high-density plug tray with 570 holes whose specifications were 53 cm long × 34 cm wide × 3.5 cm thick, and then robust, disease-free, and uniform tobacco seedlings were selected to be artificially planted in a commercially available floating seedling raising substrate. The specifications are: length 67cm×width 34cm×thickness 6cm in a 200-hole grid plate, and then place the grid plate in several small nursery pools that have been arranged in advance and continue to cultivate seedlings;

[0039] The nursery pool which is divided into several small nursery pools, its structure is as detailed in the description figure 1As shown, as follows: the nursery pool includes ...

Embodiment 2

[0051] A seedling raising method adopting an intermittent flow type nutrient liquid film, which specifically carries out the seedling raising process for tobacco seedlings according to the following steps:

[0052] (1) Using segmented seedling cultivation:

[0053] The cross-stage tobacco seedlings were bred with a high-density hole tray with 570 holes of length 53cm × width 34cm × thickness 3.5cm, and then robust, disease-free, and uniform tobacco seedlings were selected for artificial planting and filled with loam according to the weight ratio: Fine sand: the ratio of organic matter to 6:3:1 The specifications of the nutrient soil for seedling cultivation are: 58.5cm long × 32.5cm wide × 4.5cm thick 96-hole grid plate (the grid plate should be lined before filling the nutrient soil A hard board, which will be pulled out for repeated use after the belt will be placed), and then the grid plate is placed in several small nursery ponds that are divided into several small nursery...

Abstract

The invention relates to a method for growing seedlings by using an intermittent flow type nutrient liquid film. The method for growing the seedlings by using the intermittent flow type nutrient liquid film is characterized by including the step (1) of selection of a seedling growing mode and the step (2) of water and fertilizer management. By means of the method, a nutrient solution can be supplied intermittently, fertilizer is supplied step by step, fertilizer saving is achieved, and diseases and weak seedlings due to overfertilization can be avoided; due to the fact that a wetting and drying alternation seedling growing method is adopted, the long seedling recovery time after root system strongly-aquatic seedlings are transplanted is avoided, and fertilizer waste and environmental pollution due to water draining and seedling hardening are also avoided.

Description

technical field [0001] The invention relates to seedling raising of food and economic crops, in particular to a seedling raising method using an intermittent flow nutrient liquid film. Background technique [0002] At present, the seedling raising of crops such as flowers, vegetables, tobacco, cotton, fruit and food mostly adopts a two-stage method, especially in cold regions in early spring. The so-called two-stage method means that the seedlings are first grown in a high-density grid tray in a seedling raising facility, and then the seedlings are artificially planted in a relatively large grid tray, and then the seedlings are grown in floating seedlings, wet seedlings or shallow water seedlings. [0003] As a relatively new method of raising seedlings, floating seedlings refer to floating the foam trays equipped with light seedling substrates on the water surface, sowing seeds in the substrate, seedlings take root and grow in the seedling substrate, and can grow from the s...
