Soil improvement method before planting sugarcane

Abstract

The invention provides a soil improvement method implemented before sugarcane planting. The soil improvement method includes the following steps: selecting soil fertility indexes needing to be improved; determining target values of the soil fertility indexes needing to be improved; determining buffering values of the soil fertility indexes needing to be improved; measuring soil fertility indexes obtained before the improvement; determining the weight of soil of a farming soil improvement layer; building a calculation model for adjusting the soil fertility indexes to the target values; determining soil improvement materials; calculating the amount of the soil improvement material; applying the soil improvement materials, and carrying out soil improvement work. By means of the soil improvement method, the soil fertility indexes, difficult to optimize through conventional fertilizing applying and farming measures, in soil can be adjusted to be in the optimal ideal state at a time before planting is carried out, and the performance cost ratio of the selected soil improvement materials is high and the soil improvement material is easy to purchase; the soil improvement work and land cultivating and preparing before sugarcane planting are combined, the soil improvement materials can be evenly scattered in the soil accordingly, and the soil improvement work cost can not be additionally increased; the per unit area yield level of sugarcane can be improved, and particularly the per unit area yield level of perennial root sugarcane can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of sugarcane cultivation, and relates to a soil improvement method before sugarcane planting, which is suitable for use in sugarcane planting areas in my country. Background technique [0002] Sugar cane is a perennial crop that is harvested annually. At present, the main sugarcane producing areas in my country mostly adopt the planting management mode of 1-year new planting and 2-4 years of perennial roots, that is, once sugarcane is planted, it can be harvested 3-5 times, and it will be plowed and planted again after 3-5 years. Most of the soil in the main sugarcane producing areas in my country is acidic red soil, and the basic soil nutrients are lacking. Under the long-term sugarcane cultivation and fertilization mode, the imbalance of soil nutrients has caused serious adverse effects on the growth and high yield of sugarcane. Therefore, soil improved. [0003] Typically soil improvement is the applicat...

AI Technical Summary

Problems solved by technology

Since fertilization during sugarcane planting only supplies nutrients such as nitrogen, phosphorus, and potassium to local soils, it cannot improve the unfavorable conditions such as acidity in the entire root layer soil and insufficient nutrients such as phosphorus, potassium, calcium, magnesium, sulfur, zinc, and boron. The yield per unit area in the production area is very low, especially the per unit yield of rattan cane has declined greatly year by year, the benefits of sugarcane planting are poor, and the cost of sucrose production is too high, which has seriously restricted the healthy development of my country's sugarcane sugar industry
