New method for soil treatment before planting rice in slope-reformed terraces

Abstract

The invention relates to the technical field of agriculture, and especially relates to a new method for soil treatment before planting rice in slope-reformed terraces. The method reduces probability of water seepage in newly reformed terraces by compacting bottom soil of a newly opened slope-reformed terrace. By grinding the bottom soil into slurry, the soil naturally forms a base, so as to greatly improve water retention effect of the newly opened slope-reformed terrace. The structure of a ridge is firm, and anti-leakage effect is good. Through spreading a special fertilizer specially used for planting rice and vegetable waste, soil fertility of the newly-reformed terrace is improved, soil environment is improved, and adaptability of rice to adverse environment is improved, and yield ofrice is greatly increased. From an aspect of the water retention effect, the water retention time of a water layer of 5-7cm under the condition of average daily temperature of 25 DEG C (without effective natural rainfall) reaches 5-7 days, and the time of soil relative humidity >=60% increases from original 3-5 days to more than 15 days.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a new method for soil treatment before paddy planting in terraced fields. Background technique [0002] Rice has always been in a dominant position in my country's food production and consumption. More than half of my country's population takes rice as a staple food, so the consumption demand for rice is particularly large; rice is also widely distributed, and more than 90% of the country's provinces, autonomous regions and cities are There are varying degrees of rice cultivation. [0003] Rice growth requires a lot of water. Insufficient water will affect the normal production and final yield of rice. According to calculations, traditional flooded planting requires 400-600 cubic meters of fresh water per mu. If the soil water retention effect is poor, in order to ensure For the normal growth of rice, the water consumption will increase exponentially. [0004] In my countr...

Problems solved by technology

In the process of converting the original slopes into terraces, the original barren hills were simply flattened and transformed into terraced fields. Therefore, the newly transformed terraced fields have more gravel on the soil surface, loose soil structure, and poor water and fertilizer conservation. The newly reclaimed farmland The crop yield is low, and it is not even suitable for planting

Especially in rice planting, due to the need to maintain water and fertilizer all the time, but the newly reclaimed terraced fields have poor water and fertilizer retention capacity, often resulting in serious production reduction or even failure due to the loss of water and fertilizer
