Method of improving plantlet planting soil in barren hilly land

Abstract

The invention discloses a method of improving plantlet planting soil in barren hilly land, comprising: (1) clearing the weed Dicranopteris dichotoma on the surface, piling the weed aside for use, digging planting holes, separately placing the dug surface coil and core soil, and sun-curing the soil for 7-15 days; (2) spreading the weed Dicranopteris dichotoma as a first layer which has the thickness 15-20% of the depth of the planting holes, and spreading quick lime; (3) spreading surface soil as a second layer having the thickness 15-20% of the depth of the planting holes; (4) spreading formula soil as a third layer having the thickness 15-20% of the depth of the planting holes, wherein the formula soil includes formula fertilizer and core soil; (5) spreading the core soil as a fourth layer having the thickness 15-20% of the depth of the planting holes; (6) spreading formula soil as a fifth layer having the thickness 5-10% of the depth of the planting holes, wherein the formula soil isthe same as the formula soil of the third layer; (7) covering the surface with the core soil. Plantlets planted in soil improved via the method grow fast and highly neatly, and the plantlets have high quality and short outplanting time, as well as high outplanting rate.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method for planting seedlings on barren ridges and slopes. Background technique [0002] In the planting of seedlings, the success or failure of the planting is especially important to the soil of the planting site. With the increasing shortage of land around the city, the planting area of ​​seedlings on hillsides is constantly expanding. However, due to poor hillsides, compacted soil, high density, lack of nutrients, low organic matter content, and poor water and fertility retention, the growth of seedlings cannot be satisfied. demand, resulting in slow growth of planted seedlings, poor quality, and unsatisfactory planting effects. The most effective solution is to improve the soil on the hillside. [0003] At present, the main method for soil improvement on poor ridges and slopes is to dig planting holes, scatter the applied base fertilizer on the p...

Problems solved by technology

Although this method is simple and easy to operate, the added nutrients are relatively single, and it has not effectively improved the structure and physical and chemical properties of the soil. The soil is easy to harden, and still cannot meet the growth needs of seedlings, making it difficult for seedlings to grow, and it is easy to cause seedlings to grow. Bad, and the seedlings are easy to age, degrade and not grow

Especially for seedling species with strict growth requirements, if the favorable period of seedling growth in the early stage is missed, it will take a long time to cultivate in the later stage, or the aging of seedlings will occur, resulting in slow emergence of seedlings, low uniformity of emergence, and uneven growth specifications Uneven, more seedlings are eliminated, which seriously affects the production of seedlings, and the economic benefits are poor
