Method for cultivating full and strong peanut seedlings

Abstract

The invention belongs to the technical field of agricultural cultivation, and discloses a method for cultivating full and strong peanut seedlings.The method includes implementation steps of seed selecting and blending, quantitative fertilizer application, fine tilling, ridging and grooving, seed sowing and film covering, timely seedling releasing and comprehensive prevention and control.The method has the advantages that regular-triangle holes are dug on two sides of each groove in each ridge, a healthful and full peanut seed is sown in each hole, the density and the planting distances are appropriately increased, double sub-ridge mulching films cover each single ridge, nitrogen fertilizers are quantitatively applied into the middle grooves in the ridges, water evaporated under the films are sufficiently utilized in initial peanut seed germination and seedling emergence periods, accordingly, soil moisture can be preserved, the utilization rate of the nitrogen fertilizers in the grooves can be increased, illumination and accumulated temperatures can be increased, rooting and budding can be promoted, problems that full peanut seedlings cannot be germinated and peanut seedlings are not strong at seedling stages and fight for fertilizers, light and spaces due to double plants in each hole and excessively short planting distances in the prior art can be solved, the peanut seedlings cultivated by the aid of the method are full and strong, and the yield can be increased.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for cultivating whole peanut seedlings and strong seedlings. Background technique [0002] Peanut is an important economic crop and oil crop in my country. It is rich in protein and fat, has high nutritional value and is widely used. Although peanuts are crops that love drought and fear waterlogging, without proper amount of water, peanut seeds cannot germinate and grow normally. Some cotyledons that have just sprouted will lose water and die due to insufficient moisture. Therefore, it is very important to preserve moisture in the field. Moreover, sufficient light and sufficient accumulated temperature must be required to ensure the normal growth of peanuts.

Although peanuts are crops that love drought and fear waterlogging, without proper amount of water, peanut seeds cannot germinate and grow normally. Some cotyledons that have just sprouted will lose water and die due to insufficient moisture. Therefore, it is very important to preserve moisture in the field. Moreover, sufficient light and sufficient accumulated temperature must be required to ensure the normal growth of peanuts.

[0003] There are three main traditional cultivation methods for peanuts: one is flat planting, including open-air flat planting and film-covered flat planting. This cultivation method is very easy to cause marsh damage in rainy days, and it is difficult to have enough accumulated temperature, and the roots do not have sufficient light. The moisture in the planting is serious, and the fields where the peanuts are planted are dry fields, and most of the surrounding areas lack water sources, and the water in the fields is difficult to meet the needs of the normal growth of peanuts

The second is to plant in the open air on ridges. This cultivation method is very likely to cause a lack of fertilizer and water, and it is difficult to have enough accumulated temperature. It is also easy to cause hardening of the ridge surface, which is not conducive to the needle planting of peanuts during the flowering period.

The third is ridge-covered planting. This kind of ridge is generally an arched ridge. Although it has strong light and high accumulated temperature, a single row of peanuts is planted on a single ridge. The peanut is just in the middle of the ridge and evaporates from the ground during the day. When the water vapor condenses under the mulch, the water droplets accumulate too much or when the temperature cools down at night, they will slowly flow to the two sides of the ridge along the lower surface of the mulch and fall on the soil on the edge of the ridge, resulting in the ineffective use of water and some seeds cannot germinate. Emergence; most of the fertilizers are solid and not dissolved, and the utilization rate is not high, which cannot meet the needs of the initial growth of peanuts; although the seeds have sufficient temperature, they cannot germinate or grow normally after germination, resulting in high temperature rotten seeds and burning seedlings Phenomenon: Two rows of peanuts are planted on one ridge. In the early stage of peanut growth, the vegetative growth lacks strong vitality due to the ineffective use of solid fertilizers.

[0004] Insufficient soil moisture caused by the phenomenon of running moisture in the fields restricts the whole peanut seedlings; the low utilization rate of fertilizers in the peanut seedling stage restricts the growth of peanut seedlings; insufficient light and insufficient accumulated temperature restrict the rooting and growth of peanuts; The flower needles of peanuts are pricked down; in the traditional planting of peanuts with double beads in one hole, after the seeds germinate, they compete for fertilizer, glory and space, which restricts the yield of peanuts

These factors restrict the planting benefits of peanuts
