Method for cultivating machine-transplanted bowl body strong tiller seedling in easy water leakage soil

Abstract

The invention provides a method for cultivating machine-transplanted bowl body strong tiller seedling in easy water leakage soil, belonging to the technical field of crop cultivation. The cultivatingmethod comprises the following steps: (1) accelerating germination of seeds until the seeds are broken and white buds appear, and drying to obtain germinated seeds; (2) sowing that germinated seeds into the nutrient soil in the seedling tray, darkening for 2 to 3 days to obtain a seedling emergence tray; (3) placing that seedling emergence tray on the seedling bed, covering the bed with a non-woven cloth, pouring PAOMA water, removing the membrane when the leaf age of the seedling reach one leaf and one core stage, and performing the promoting and controlling of the seedling. As that promotingand controlling operation is carried out during the seedling stage, the fertilizer can be prevented from leaking with water, the chemical control agent effective ingredient can be prevented from being diluted and the concentration can be prevented from being reduced, so that the chemical control effect is prevented from being weakened, thereby playing a romoting and controlling role of topdressing fertilizer and chemical control. Compared with the conventional seedling raising method, the invention has the advantages of uniform seedling emergence, more roots, strong seedling, 0.6-0.8 increasetiller / hole and about 5% rice yield increase in the later stage.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for cultivating strong seedlings with tillers in soil prone to water leakage. Background technique [0002] Due to the large amount of sowing in the conventional blanket seedling raising tray, the quality of the seedlings is relatively weak, and the overage seedlings are often unable to be transplanted with high quality, and it is difficult for conventional blanket seedling machine transplanting to fully develop the potential of rice yield and quality in areas where temperature and light resources are scarce. Machine-transplanted seedlings in bowls are transplanted into large fields where the strong seedlings raised in bowls are evenly spaced according to a certain row without plant injury. The key innovation point of this technology is to use the supporting planting line technology to cultivate strong seedlings with a seedling age of 25-35 days...

Problems solved by technology

However, farmers will encounter the following problems in the production process according to the above operation steps. On the one hand, a large amount of fertilizer is applied to fertilize the nutrient soil and seedling boards, which has the risk of burning seedlings. The nutrient soil is mixed with seedling strengthening agents, and it is difficult for farmers to control the dosage. Or it is easy to mix the soil unevenly, and the germination rate of rice seeds often decreases, and the emergence of seedlings is uneven (the seedlings grow short in places where there are many seedling strengthening agents, and the places where there are few seedlings are easy to jump up); Leaky soil, because of its poor water and fertilizer retention performance, and the short water storage time of the soil ball in the pot hole, in high temperature weather, the seedling field needs to be watered several times to keep the pot hole moist, which makes the nutrient soil and the fertilizer in the seedling bed easy to seep with water Leakage, and the seedling strengthening agent is repeatedly diluted, the concentration is reduced, and the chemical control function is lost. The effect of fertilizer and seedling strengthening agent is weakened, and the "promoting control" effect cannot be effectively exerted. Eventually, the seedlings are slender and without tillers, and cannot form Strong seedlings
