Embodiment 1

[0017] Embodiment 1: a kind of method for rice mechanized seedling raising, comprises the following steps,

[0018] Step S1: Straw tendon treatment: Soak the straw tendon with 20 times the vinegar solution, and wash it with clean water after 24 hours.

[0019] Step S2: Select the seedling-raising substrate: the seedling-raising substrate is obtained by thoroughly mixing fine vinegar grains, vermiculite and peat in sequence at a volume ratio of 66.7%: 16.65%: 16.65%, wherein the physical and chemical indicators of the seedling-raising substrate are: bulk density 0.26g / cm 3 , the total porosity is 68%, the available potassium content is 8.30g / kg, the available nitrogen content is 0.77g / kg, the available phosphorus content is 0.23g / kg, the EC value is 2.17mS / cm, and the pH value is 6.39. The crushed product of industrial waste vinegar grains, the physical and chemical indicators are: bulk density 0.26g / cm 3 , available potassium content 9.09g / kg, available nitrogen content 0.79g...

Abstract

The invention relates to a method for mechanically raising rice seedlings. The method comprises the following steps of straw rib treatment: soaking straw ribs by using vinegar which is diluted by 20 times, and cleaning by using clear water after 24 hours; seedling growing medium selection: a seedling growing medium is prepared by fully and evenly mixing and stirring 66.7 percent of fine vinegar residue, 16.65 percent of vermiculite and 16.65 percent of turf according to a volume ratio in sequence; seeding: seeding by adopting a seeding mode of a seeding machine; paving the treated straw ribs in rice seedling raising plates; paving the rice seedling raising plates in which the straw ribs are paved on a ridge of a rice seedling field; covering the rice seedling raising plates by non-woven cloth and keeping the water level, and carrying out machine transplanting of the rice seedlings for use after 18 days. According to the method for mechanically raising the rice seedlings, disclosed by the invention, the problem of seedling leakage caused by easiness in plate scattering of mechanical rice seedling transplanting of plastic plate rice seedling raising adopted by current production can be effectively solved, the machine-transplanting working efficiency is greatly increased, and the loss of the rice seedlings is reduced.

Description

technical field [0001] The invention relates to the field of rice seedling raising, in particular to a method for mechanized rice seedling raising. Background technique [0002] Seedling raising is one of the important links in the early stage of rice production, because the quality of seedlings is directly related to the growth and appearance of rice in the early stage and the yield frame in the later stage. Therefore, rice production has always attached great importance to the cultivation of seedling quality. According to the changes of the times and the progress of technology, rice seedling raising includes water seedling raising, wet seedling raising, dry seedling raising, floppy seedling raising and industrial seedling raising. But the current degree of mechanization is not high, and there is no unified system. Contents of the invention [0003] In view of the above-mentioned deficiencies existing in the current technology, the present invention provides a method for...
