Nutrient soil for watermelon planting and preparation method of nutrient soil

Abstract

The invention discloses nutrient soil for watermelon planting. The nutrient soil is prepared from cinder, river sand, loess, corncob, bone meal, straw and ammonium nitrate. A preparation method of thenutrient soil comprises the following steps: the cinder and blocky loess are ground; the ground cinder and loess are mixed with the river sand, and the mixture is steamed in a steamer for 3 h for sterilization; the corncob and the straw are crushed by a crusher; the obtained raw materials are mixed with the bone meal, and the mixture is dried in the sun; the obtained raw materials are mixed withammonium nitrate, and the nutrient soil is prepared. Loose and breathable soil is provided for watermelon planting, the soil is moderate in pH and lower in salinity, has better water storage capacityand is rich in various nutrients needed by watermelon growth, and the nutrients are not prone to loss and are beneficial to watermelon growth.

Description

technical field [0001] The invention relates to a nutrient soil, in particular to a preparation method of a watermelon planting nutrient soil. Background technique [0002] Watermelons are more drought-tolerant and barren-tolerant. However, because the watermelon root system is aerobic, it needs sufficient air in the soil. It is most suitable for well-drained, deep loam or sandy loam. It has good air permeability, fast water plant infiltration after rainfall or irrigation, fast ground temperature rise in early spring, rapid night heat dissipation, large temperature difference between day and night, strong seedling growth, more fruit sugar accumulation, and good quality. However, sandy land is generally relatively barren, and fertilizer decomposition and nutrient consumption and loss are fast. Plants often lose fertilizer in the later stage of growth, and their growth potential becomes weak, and they are prone to aging and disease; while newly reclaimed wasteland and clay l...

Problems solved by technology

However, sandy land is generally relatively barren, and fertilizer decomposition and nutrient consumption and loss are fast. Plants often lose fertilizer in the later stage of growth, and their growth potential becomes weak, and they are prone to aging and disease; while newly reclaimed wasteland and clay land have poor ventilation and low ground temperature. , slow seedling growth, late fruit ripening, and poor quality; watermelon is suitable for planting in neutral soil, and has wide adaptability to soil pH, and can grow normally in the range of pH 5 to 7. Watermelon is more sensitive to salinity and soil If the salt content is higher than 0.2%, it will not grow normally

In addition, the soil is too sticky, the groundwater level is too high, the land is low-lying and prone to water accumulation, and the land with heavy cropping is not suitable for planting watermelons.
