Embodiment Construction

[0023] Such as figure 1 and 2 Shown, a kind of paddy rice two-stage seedling raising device comprises a plurality of stacked seedling raising trays 1, and the seedling raising tray 1 includes a rectangular frame with a bottom plate 12, and the frame 11 height of the rectangular frame is 28mm, and the bottom plate 12 A circle of frame-type ribs 13 is provided on the peripheral side of the frame, and reinforcing ribs 14 are also provided on both sides of the bottom plate 12, and the frame-type ribs 13 and reinforcing ribs 14 are used to connect with the rectangular frame of the seedling raising tray below it. The frame 11 is clamped.

[0024] A method for cultivating seedlings using a second-stage rice seedling raising device, comprising the steps of:

[0025] 1), such as figure 2 As shown, add subsoil 2 or matrix in each seedling tray 1, subsoil 2 or matrix are higher than 2 / 3 of the frame 11 height of the rectangular frame of seedling tray 1 and have 5-8mm distance from th...

Abstract

The invention discloses a two-stage rice seedling raising device and a two-stage rice seedling raising method. A rectangular rice seedling raising tray with a frame having a certain height at the periphery and a frame-type rib which protrudes downwards at the outer bottom is used for seeding and raising seedlings, the rectangular rice seedling raising trays are stacked after seeding, and the rice seedling raising tray on the top is also covered, so that each rice seedling raising tray forms a dark environment for seedling sprouting. The sprout of rice seeds is accelerated by dark environment formed by the rice seedling raising tray, the seed sprouting uniformity can be improved, the operation is simple, and the two-stage rice seedling raising device can be used for solving the problems that rice mechanical transplanting causes slow and non-uniform seedling.

Description

technical field [0001] The invention relates to rice planting technology, in particular to a rice two-stage seedling raising device and a method thereof. Background technique [0002] Rice seedling emergence is an important link in rice production. The rice seedling emergence process requires suitable temperature, moisture and oxygen. The emergence of rice seedlings is easily affected by the soil environment and weather. Problems such as rotten seeds, rotten seedlings, irregular seedling emergence, poor seedling quality, and frequent seedling diseases often occur. Rice machine transplanting mainly adopts blanket seedling machine transplanting technology. Blanket seedling raising usually uses a standard seedling tray, put seedling soil or seedling substrate in the seedling tray, sow the seeds on the soil, and then cover the seeds with soil. After the seeds grow Form blanket seedlings. Therefore, seed emergence is extremely important for the formation of blanket seedlings, e...
