Paddy soilless transplant-free quick seedling raising method and seedling raising net as well as seedling raising rack thereof

Abstract

The invention discloses a paddy soilless transplant-free quick seedling raising method and equipment. The method comprises the following steps: a, preparing seedling raising nets, i.e., manufacturing square seedling raising nets by using a perishable and degradable biomass material, wherein the two ends of the seedling raising nets are fixed to fixing rods; b, transplanting seeds, i.e., transplanting the seeds in the seedling raising nets, wherein one ends of the seeds with embryos are exposed outside the net material and are in the same direction, and 2-3 seeds are transplanted for each plant; c, soaking to sprout, i.e., placing and soaking the seedling raising nets in which the seeds are transplanted in the previous step in a sprouting pool to sprout, and draining water in the pool and covering with thin films when the seeds are budded; and d, putting on the rack to raise seedlings, i.e., moving the seedling raising nets to an outdoor seedling raising rack when the seedlings are grown to 1-2 mm, covering with the thin films, watering once per hour, reserving holes in the thin films at the two ends of the seedling raising rack to ventilate when the seedlings are grown to 1.5 cm, removing the thin films to expose the seedlings in air when the seedlings in the seedling raising rack are grown to 8-10 cm, and transplanting into a paddy field after removing the thin film for 3-4 days.

Description

technical field [0001] The invention relates to a method for raising rice seedlings, in particular to a method for quickly raising rice seedlings without soil and without transplanting. It also relates to a seedling raising net and a seedling raising frame for realizing the method. Background technique [0002] The planting of rice all has the steps of raising seedlings in the field and transplanting rice seedlings, and raising seedlings in the field and transplanting rice seedlings are both time-consuming and laborious manual labor. Especially in the southern mountainous and hilly forest areas, the fields are small, scattered, and irregular, and mechanized operations cannot be realized. Field seedling raising and transplanting must be done manually. The management requirements for seedling raising are strict, and seedling raising takes a long time.

Problems solved by technology

[0002] Rice planting involves the steps of raising seedlings in the field and transplanting them in the field, which are both time-consuming and labor-intensive manual labor.

Especially in the southern mountainous and hilly forest areas, the fields are small, scattered, and irregular, and mechanized operations cannot be realized. Field seedling raising and transplanting must be done manually. The management requirements for seedling raising are strict, and seedling raising takes a long time. Consume a lot of manpower and material resources

Although there are soilless seedling raising techniques now, they all rely on artificially made or purchased seedling trays or seedling bases. The production of seedling trays or seedling bases is complicated, and the seedling raising technology requires high requirements, high cost, and low efficiency. use, so it is difficult to popularize; and after raising seedlings, it is necessary to manually complete the work of transplanting or throwing seedlings, and it is always difficult to throw seedlings neatly

At present, most of the young and middle-aged laborers in rural areas are working in cities, and heavy physical labor such as rice seedling raising and transplanting can no longer be completed normally, so many rice fields are deserted
