Embodiment 1

[0031] The test site was selected to be carried out in the experimental field of the Jiangsu Lixiahe District Agricultural Science Institute, Wantou Town, Yangzhou City, Jiangsu Province. The rice variety used was Yangjing 4227. Two sets of high-absorbent seed coating agent-coating machine transplanting seedlings and uncoated machine transplanting seedlings were set up. For each treatment, 10 trays are sown for each treatment, and the seeding amount of each tray is 120 grams of dry seeds.

[0032] 1. Nutritional soil configuration: Accurately weigh 60 kg of paddy field surface soil through a 20-mesh sieve, and 750 grams of special fertilizer for machine-transplanted seedlings and seedlings (N-P-K content 19%) 750 grams, mix the two evenly, and prepare machine-transplanted seedlings for nutrition earth.

[0033] 2. Seed coating: Accurately weigh 1200 grams of Yangjing 4227 rice seeds and soak in clean water for 20 minutes, remove the rice seeds, drain off excess water, pour 40 ...

Abstract

The invention discloses an application of a high water-absorbing seed coating in prolonging mechanical transplanted seedling age of rice. The high water-absorbing seed coating is a Duo.Duozuo seed-dressing agent, the commercial number of which is drought-foster nurse. The using steps comprise matching of nutrient soil, seed coating, plate swinging and sowing, seedling management and the like. According to the application, the rice seeds are coated by using the high water-absorbing seed coating to culture mechanical transplanted seedlings, so that diseases such as bakanae disease, damping off and the like can be prevented and treated and the quality of the seedings is improved, and the suitable planting age of the mechanical transplanted seedlings is greatly prolonged. Moreover, the seeding-growing link of the mechanical transplanted seedlings is reduced, the labor and medicinal costs are lowered, and the breeding level of the mechanical transplanted seedlings is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to the application of a superabsorbent seed coating agent in prolonging the age of machine-transplanted rice. Background technique [0002] Rice is an important food crop in my country, and rice cultivation techniques in different regions are also complicated. As a light-duty rice cultivation technology integrating mechanization, intensification, scale and industrialization, rice machine transplanting technology has become a key promotion in my country. The light and simple cultivation technology of rice, the application area is expanding year by year. [0003] The seedling raising method and planting technology of rice transplanting technology are essentially different from other cultivation techniques. First, the sowing location is not limited to the farmland, but also in the greenhouse factory (multi-layer placement), or in hard cement On the ground; secondly...
