Method for transplanting rice seedlings and raising rice seedlings through rice machine

Abstract

The invention discloses a method for transplanting rice seedlings and raising the rice seedlings through a rice machine. The method comprises the following steps that a field block which is leeward, apricus, fertile in soil and convenient to manage is selected as a seedling bed; an organic matrix is prepared; seeds are treated; for each plate, conventional rice seeds range from 120 g to 140 g, hybrid rice seeds range from 80 g to 100 g, and covering is conducted with soil for 0.5 cm after the seeds are sowed; an arch frame is built with bamboo chips, the arch frame is 30 cm-40 cm high, spacing is 50 cm, and the arch frame is covered with thin film; after the seeds sprout, the field is kept moist, after a leaf has one leaf center, the film is removed, seedling exercising is conducted at the temperature ranging from 20 DEG C to 25 DEGC, water controlling and seedling exercising are conducted three days before transplanting, fertilizer applied before transplanting is applied once at dusk, and 4 kg of urea mixed with 500 kg of water is watered to a rice seedling bed per mu at dusk. According to the method for transplanting the rice seedlings and raising the rice seedlings through the rice machine, the organic matrix is adopted for raising the seedlings, the speed of emergence is high, the seedling quality is good, root systems of seedlings are developed, and the number of white roots is increased; matrix seedling raising and seeding are good in uniformity, and few pest diseases and weeds exist; by means of the method for transplanting the rice seedlings and raising the rice seedlings through the rice machine, the seedling raising cost is reduced, consumption on surface soil is avoided, and a good protective effect on farmland is achieved.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a method for machine-transplanted and raised rice seedlings. Background technique [0002] Traditional rice machine-transplanted seedlings are mainly based on field soil or nutrient soil. The specifications of the general seedling-raising should be plastic trays with a length of 58 cm, a width of 28 cm, and a height of 2 cm. With such a seedling tray, the average amount of field soil or The nutrient soil is about 80 kg. Based on the area of ​​200,000 mu of machine-transplanted rice in a certain area, 133 mu of fertile land is needed as a soil source for machine-transplanted seedlings every year, resulting in a serious loss of surface mellow soil. [0003] As a modern rice production method, machine transplanting has the characteristics of high operating efficiency, labor and labor saving, and increased production and efficiency. It is the development trend of m...

Problems solved by technology

At present, the main bottleneck restricting the development of machine-transplanted seedlings is the quality of seedlings and the source of nutrient soil.
