Method for cultivating mechanized transplanted seedlings of rice by use of organic medium production line in gutter-connected plastic greenhouse

Abstract

The invention discloses a method for cultivating mechanized transplanted seedlings of rice by use of an organic medium production line in a gutter-connected plastic greenhouse. The method comprises the following steps of 1), arrangement of cultivating seedling materials, namely a medium, a seedling disk, a dome-shaped steel-structure plastic film gutter-connected glasshouse facility, and a finishing seedbed; 2), seed treatment, namely choosing seeds, soaking the seeds and accelerating germination; 3), medium treatment and disk loading, namely firstly loading a bottom-layer medium, then seeding, finally covering the seeds with the medium and watering; 4) seeding and bud promotion, namely seeding dry rice and bud rice in each disk, stacking the disks and promoting bud, moisturizing, warming, arranging the disks, and performing atomizing spray, wherein the disk stacking height is 20 layers; and 5) seedling stage management, namely attentively managing the temperature and moisture and controlling diseases. The method has the advantages of good technical effect, obvious social benefit and prominent economical and ecological benefits and the like, and the method has preferable popularization prospect.

Description

technical field [0001] The invention belongs to a technical method for raising seedlings by machine-transplanted seedlings in rice cultivation, and in particular relates to a method for sowing and cultivating blanket-shaped machine-transplanted seedlings by using an organic matrix assembly line in a double-span greenhouse plastic shed. It is closer to factory production, saves time, labor, and labor, and the speed of seedling emergence is fast, and the seedlings grow well and have good quality, which is conducive to large-scale seedling cultivation. Background technique [0002] Rice is the second largest food crop in the world, the first in Asia, and the first in my country. With the acceleration of urbanization in my country and the rapid reduction of the rural labor force, it is an inevitable choice to carry out the mechanization of rice production and realize the modernization of rice farming. Other management links of rice production, such as arable land, land preparat...

Problems solved by technology

The first disadvantage is that the working environment in the open field is poor, mainly relying on manual work, which is laborious; the second is that the small non-woven arch shed needs to be built every year, which is laborious and wastes materials; ; Fourth, it is difficult to level the seedling bed, and the low-lying areas have a lot of water and high humidity, which affects the emergence of seedlings.

The density of seedlings is high, and diseases are prone to occur; fifth, the weight of nutrient soil is heavy, and the operation is laborious, which is very inconvenient for raising and transporting seedlings, which is time-consuming and labor-intensive, and has a certain impact on the efficiency of machine transplanting

Although the investment is small, it is difficult to repeat the promotion under the current conditions of lack of rural labor force
