Problems solved by technology

This kind of seedlings with too high seedling height has problems such as many seedlings, high rate of seedling damage and missed transplanting, and long greening period due to their slender and delicate during machine transplanting operations, which leads to the advantages of machine transplanting technology to increase production can't be used effectively
Moreover, based on the fact that the seedling height is too high, whether it is during the seedling cultivation period or after

Example Embodiment

[0021] Example 1

[0022] The invention is a method for cultivating single-hole rice seedlings for transplanting by a rice transplanter. Among them, the required single-hole rice seedlings have a seedling age of 35 to 45 days, a leaf age of 4 to 7, and a seedling height of no more than 250 mm. This single-hole rice seedling cultivation method includes the following steps:

[0023] 1). Select high-quality rice seeds. The specific selection requirements are: rice seeds with full grains, deflated grains ≤5%, and sprout rate ≥98%, that is, the quality of the selected seeds must meet the national standards. At the same time, prepare plug trays. The plug trays are polyvinyl chloride plastic soft plug trays. The overall outline size should meet the requirements of the rice transplanter. The general size is 610×315mm. There are several bowls on the plug tray; each bowl on the plug tray is required. The length and width of the mouth of the body are 15mm respectively. If the body is a roun...

Abstract

The invention discloses a method for cultivating single-cave rice seedlings for mechanical rice transplanting. The age of the single-cave rice seedlings is 35-45 days, the leaf age is 4-7 leaves, and the seedling height is not greater than 250mm. The method comprises the following steps: (1) selecting high-quality seeds and preparing cave discs, wherein the mouth of each bowl on the cave discs is 14-18mm in length and 14-18mm in width, the bottom of each bowl is 11-15mm in length and 11-15mm in width, and the depth of each bowl is 22-28mm; (2) filling cultivation soil inside the bowls of the cave discs, wherein the cultivation soil inside each bowl accounts for 2/3 of the volume of each bowl; (3) planting seeds in the cave discs, and covering cultivation soil of 3-5mm in thickness into the cave disc bowls subjected to seeding, wherein the number of seeds in each bowl is 1-4; (4) placing the cave discs subjected to seeding on a seedbed, and performing seedling management in a dry nursery seedling management mode. By adopting the method, compact winding of rice seedling root systems is achieved in a single-cave low-density seedling manner, the height of rice seedlings is limited, the requirements of mechanical rice transplanting of bowl-shaped blanket-shaped rice seedlings are met, and the yield increase advantages can be brought into play.

Description

technical field [0001] The invention relates to a method for growing seedlings of agricultural crops, in particular to a method for growing rice seedlings with a single hole inserted by a machine. Background technique [0002] With the development of society and economy, the transfer of rural labor force is accelerating and the phenomenon of rural labor force aging is becoming more and more serious. The traditional rice planting method based on hand-transplanted rice seedlings is no longer suitable for the development of modern rice cultivation technology in my country's socio-economic development. In this context, mechanical transplanting technology came into being. The key to the mechanical transplanting technology lies in the grasping of the seedlings and the continuity of the supply of the seedlings on the mechanical equipment. At present, the machine-transplanting technology with better application effect is the machine-transplanting technology of bowl-shaped blanket-sh...
