Problems solved by technology

The planting technology of seedlings generally adopts the technology of mechanical planting after seedling cultivation in developed areas, while the traditional manual planting method is still used in underdeveloped areas. This traditional technology is inefficient
However, the technical efficiency of mechanical planting still needs to be improved, and the cost of maintenance after planting is relatively high, so the planting technology of seedlings needs to be further improved

Embodiment 1

[0017] A planting technique for seedlings, the process steps comprising:

[0018] (1) Flat land: The land for planting is selected to be a slightly acidic field with deep soil, loose and fertile soil, and a good aggregate structure. 10cm above the soil surface, the soil is crushed to form mud, and the ground is prepared with a width of 2.0 meters, and planted in a north-south direction;

[0019] (2) Retting: Sprinkle fertilizer on the field. The fertilizer components are: 15% decomposed cow dung, 55% plant ash, 10% general calcium as base fertilizer and 20% compound fertilizer. The amount of fertilizer applied per mu of field 500 kg, retting for 7 days;

[0020] (3) Sowing seeds: spread the seedlings in the ground, after the seedlings are spread, use a plow to pat the seeds, and the spreading density is 200 grains / m 2 At this time, the air humidity is high, 85%, and the temperature is kept at 28°C, and the roots can take root after 20 days;

[0021] (4) Thinning and transpl...

Embodiment 2

[0024] A planting technique for seedlings, the process steps comprising:

[0025] (1) Flat land: The land for planting should be a slightly acidic field with deep soil, loose and fertile soil, and a good aggregate structure. 5cm above the soil surface, the soil is broken to form mud, and the furrows are prepared with a width of 1.5-2.0 meters, and the furrows are planted in a north-south direction;

[0026] (2) Retting: Sprinkle fertilizer on the field. The fertilizer components are 20% decomposed cow dung, 50% plant ash, 10% general calcium as base fertilizer and 20% compound fertilizer. The amount of fertilizer applied per mu of field 200 kg, retting for 5 days;

[0027] (3) Sowing seeds: spread the seedlings in the ground, after the seedlings are spread, use a plow to pat the seeds, and the spreading density is 150 grains / m 2 At this time, the air humidity is high, 60%, and the temperature is kept at 20°C, and the roots can take root after 20 days;

Embodiment 3

[0031] A planting technique for seedlings, the process steps comprising:

[0032] (1) Flat land: The land for planting is selected to be a slightly acidic field with deep soil, loose and fertile soil, and a good aggregate structure. Above the soil surface by 8cm, the soil is crushed to form mud, and the furrows are prepared with a width of 1.8 meters, and the furrows are planted in a north-south direction;

[0033] (2) Retting: Sprinkle fertilizer on the field. The fertilizer components are: 10% decomposed cow dung, 65% plant ash, 5% general calcium as base fertilizer and 20% compound fertilizer. The amount of fertilizer applied per mu of field 350 kg, retting for 7 days;

[0034] (3) Sowing seeds: spread the seedlings in the ground, after the seedlings are spread, use a plow to pat the seeds, and the spreading density is 180 grains / m 2 At this time, the air humidity is high, which is 80%, and the temperature is kept at 25°C, and roots can take root after 20 days;

Abstract

The invention discloses a rice seedling planting technology. According to the rice seedling planting technology, fertilizer used in the step (2) is prepared from components as follows: 5%-20% of decomposed cow dung, 40%-65% of plant ash, 5%-10% of single superphosphate as base fertilizer and 10%-20% of compound fertilizer, and fertilizer efficiency of the field can be improved sufficiently in advance by the aid of the fertilizer; after rice seedling seeds are sown in the step (3), the seeds are pressed by a plough, and the seeds can be rapidly planted in soil with the method; the rice seedlings are subjected to irrigation and fertilizer application once 5 days before transplanting in the step (4), so that seedling death in the transplanting process can be prevented, wherein a fertilizer application method comprises steps that the compound fertilizer is dissolved in water, 5-7.5 kg / 100 L of water is utilized, a fertilizer solution is splashed to the rice seedlings, and the fertilizer can be absorbed by the rice seedlings rapidly; the irrigation frequency in the step (5) is as follows: 1-2 times of irrigation is performed each week in July and august and 1-2 times of irrigation is performed once in September, and sufficient water can be provided for growth of the rice seedlings under the frequency.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a seedling planting technology. Background technique [0002] my country is a large agricultural country, and the amount of pesticides is very large. The planting technology of seedlings generally adopts the technology of mechanical planting after seedling raising in developed areas, while the traditional manual planting method is still used in underdeveloped areas, which is inefficient. However, the technical efficiency of mechanical planting still needs to be improved, and the cost of maintenance after planting is relatively high, so the planting technology of rice seedlings needs to be further improved. Contents of the invention [0003] A planting technique for seedlings, the process steps comprising: [0004] (1) Flat land: The land for planting should be a slightly acidic field with deep soil, loose and fertile soil, and a good aggregate structure. , the water surface exceed...
