specific Embodiment approach

[0014] A method for raising seedlings on a seedling tray in the open, which comprises the following steps:

[0015] Step 1. Seedling field arrangement: select the original seedling field, prepare the land according to the water culture method, plow the field three times, and harrow the field four times. No base fertilizer is applied to the bottom of the seedlings to meet the requirements of Tianping mud;

[0016] Then, release water to the seedling field to make borders, and dig border ditches on the border side to collect the mud in the border ditches, where the border width is 1.5-1.6 meters;

[0017] Sprinkle compound fertilizer in the furrow, and mix the compound fertilizer and mud thoroughly;

[0018] Step 2. Placing the tray and filling: Place the seedling tray on the border, fill the mud in the border into the seedling tray, after filling, use a wooden board to flatten the seedling tray;

[0019] Step 3. Sprouting seeding: germinate the grain seeds according to the three-soaking ...

Abstract

The invention provides an open-air seedling raising method through seedling trays, which comprises the following steps of: arrangement of a seedling bed, namely selecting the original seedling raising bed, performing soil preparation by a water raising method, feeding water to the seedling bed, making furrows, dredging a furrow trench on the side of each furrow, merging slurry into the furrow trenches, and scattering a compound fertilizer in the furrow trenches; the placement of the seedling trays and slurry filling, namely placing the seedling trays on the surfaces of furrows and filling the slurry in the furrow trenches into the seedling trays; germination hastening and seeding, namely germinating grain seeds, scattering the germinated grain seeds on the surface of the slurry in the seedling trays, and smearing the slurry; and the management of seed beds, namely after seeding, airing the bed to raise seedlings, sprinkling herbicide when the seedlings are raised to reach the two-leaf and one-core period, watering and applying urea to the seedling trays in the second day after sprinkling the herbicide, draining water of the seedling trays after two days, keeping the semiarid state of the seedling trays, and removing the seedling trays after the seedlings are raised to reach the four-leaf and one-core period. The method has the advantages of short seedling raising period, simple seedling raising process, low cost, time saving, labor saving, no plant diseases and insect pests of the raised seedlings and low incidence of diseases of the seedlings after seedling transplantation.

Description

Technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for raising seedlings on a seedling tray in the open air. Background technique [0002] Mechanized rice transplanting has the characteristics of time saving, labor saving, standardized seedling transplanting, and high yield. It is popular among farmers; however, mechanized rice transplanting requires seedling trays with seedlings. Usually, seedling trays require special seedling nutrient soil. And cumbersome disinfection measures, and start in the early spring, the seedling cycle is too long, the process is complicated, time-consuming and labor-consuming. The most important thing is that the seedlings raised by this method are prone to diseases and insect pests, and the safety is poor, especially easy to cause unstable rice yield. , Has a certain risk and is not conducive to national food security. [0003] For this reason, people have been looking for a suitable solution. Su...
