Problems solved by technology

However, it has been found in production practice that although good results can be achieved by using superabsorbent seed coating agent for seed coating, there are still technical difficulties. Seeds are easy to stick to machinery, making it difficult to sow
Some farmers also think that seed coating increases the workload and operation difficulty

Embodiment 1

[0028] According to the preparation of 500 kilograms of nutrient soil for rice long seedling age and strong seedlings in the preparation cultivation machine, accurately weigh 1.15 kilograms of superabsorbent seed coating agent, 2.5 kilograms of nursery companion, and 496.35 kilograms of sieved paddy field topsoil, and produce the above-mentioned materials according to the production process, to get final product Nutritive soil for machine-transplanted rice with long seedling age and strong seedlings.

[0029] The test site was selected to be carried out in the experimental field of the Agricultural Science Institute of Jiangsu Lixiahe District, Wantou Town, Yangzhou City, Jiangsu Province. The test time was 2015. According to the standard machine transplanting tray (58cm×28cm×2.5cm), each tray was filled with 3.0 kg of subsoil, covered The proportion of soil is 0.9 kg for machine-transplanted seedlings, moist seedlings, set up machine-transplanted rice long seedlings strong see...

Embodiment 2

[0046] According to the preparation of 500 kilograms of nutrient soil for rice long seedling age and strong seedlings in the preparation cultivation machine, accurately weigh 1.30 kilograms of superabsorbent seed coating agent, 3.35 kilograms of nursery companion, and 495.35 kilograms of sieved paddy field topsoil, and produce the above-mentioned materials according to the production process, to get final product Nutritive soil for cultivating machine-inserted rice with long seedling age and strong seedlings.

[0047] Contrast nutritional soil preparation: Accurately weigh 3.35 kg of seedling-growing companion, sieve 496.65 kg of paddy field topsoil, pre-mix with a small amount of paddy field topsoil and seedling-growing companion, then add them together to the remaining paddy field topsoil and mix in a mixer until Mix evenly to obtain comparative nutrient soil.

[0048] The test site was selected at the Zitong Experimental Base of Sichuan Shuyu Agricultural Science and Techno...

Abstract

The invention discloses a preparation method of nutrient soil for cultivating mechanical-transplanting rice long-age strong seedlings. The preparation method is characterized in that the nutrient soil is prepared by mixing three types of ingredients, namely sieved blank soil, high-hydroscopicity resin seed-coat and a seedling rearing fertilizer for the mechanical-transplanting seedlings. By virtue of applying the nutrient soil to perform seedling rearing of the mechanical-transplanting seedlings, not only can the suitable planting seedling age of the mechanical-transplanting seedlings be greatly prolonged, but also disease damage during a seedling stage of the mechanical-transplanting seedlings can be prevented, the coiled root force of the seedlings can be increased, the seedling quality is improved, and the seedling rearing level of the mechanical-transplanting seedlings is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a preparation of nutrient soil for cultivating machine-transplanted rice with long seedling age and strong seedlings. [0002] system method. Background technique [0003] Agricultural mechanization is the only way for my country's agricultural modernization. Rice is an important food crop in my country, and rice machine transplanting technology has become a light and simple rice cultivation technology that is currently being promoted in my country, and the application area is expanding year by year. [0004] At present, there are two main methods of transplanting seedlings by machine, one is the method of raising seedlings with nutrient soil, and the other is the method of raising seedlings with matrix. Nutrient soil seedling has the advantages of simple operation, low cost, high safety, and good seedling quality. It is the main method of machine-transplan...
