Embodiment 1

[0042] In 2011, 20 mu of arable land was newly reorganized in Hongshi Town, Hengyang County. On September 20, 2011, deep dry tillage (plow layer greater than 25cm) was carried out, the land was leveled, and the surrounding ditches and side ditches were opened according to the location of the drainage outlet and water inlet and the green manure planting technology. Ditch, so that the paddy field forms a "ten" or "well"-shaped ditch system. The side ditch should be deep, and the middle ditch and waist ditch can be slightly shallower. Rain does not accumulate water. Sow milk vetch alone or mix milk vetch and other green manures, and leave the winter fallow fields, and do not sow any winter green manure crops. The early rice planting method is transplanting. 100% chemical fertilizer treatment is set on the winter fallow fields, and the dosage of nitrogen, phosphorus and potassium fertilizers are respectively 10kg N / mu and 5kg P 2 o 5 / mu, 6kg K 2 O / mu is applied, and the tre...

Embodiment 2

[0050] In 2011, 30 mu of cultivated land was selected to be reorganized in Gaoqiao Town, Changsha County. On September 27, 2011, deep dry tillage (plow layer greater than 25cm) was carried out to level the land. According to the location of the drainage outlet and water inlet and the green manure planting technology, the surrounding ditches and side ditches were dug, and the middle ditches and waist ditches were dug at the same time. Ditch, so that the paddy field forms a "ten" or "well"-shaped ditch system. The side ditch should be deep, and the middle ditch and waist ditch can be slightly shallower. Rain does not accumulate water. Sow milk vetch alone or mix milk vetch and other green manures, and leave the winter fallow fields, and do not sow any winter green manure crops. The planting method of spring corn is transplanting. 100% chemical fertilizer treatment is set on the fallow field, and the amount of nitrogen, phosphorus, and potassium fertilizers are respectively 16k...

Abstract

The invention discloses a method for rapidly improving the soil fertility of new consolidated cultivated land. The method comprises the following steps: performing deep ploughing on the new consolidated cultivated land in mid-to-end of September; ditching the cultivated land according to the Chinese milk vetch green manure planting technology; applying 30-50kg/mu of calcium-magnesia phosphate fertilizer and 3-6kg/mu of potassium chloride to the cultivated land to serve as base fertilizer after ditching; then, levelling the cultivated land; performing mixture sowing by matching Chinese milk vetch seeds and one or two of other seeds of green manure crops; sowing the seeds of green manure crops by sections and times when the mixture sowing is performed; performing the routine management of green manure planting after sowing; turning up and rolling green manure in mid-to-end of April the next year; then, keeping the soil wet and retting for 8-10 days, and then, levelling the soil according to the planting requirements of next-stubble crops.

Description

technical field [0001] The invention relates to a method for rapid soil fertilization of newly rearranged cultivated land. Background technique [0002] Soil is the material basis for human survival, the most basic means of production for agricultural activities and an indispensable and non-renewable natural resource for human beings. With the continuous increase of the population, the per capita arable land area in my country has dropped from 1.59 mu per capita in 1996 to 1.38 mu in 2006 (the results of the 2006 National Land Use Change Survey), a decline of 13.3%, which is less than the world average per capita level. 40%. Hunan Province is a large agricultural province with a shortage of cultivated land resources. The per capita cultivated land area in the province is only 0.75 mu, which is already lower than the warning line of 0.78 mu per capita established by the Food and Agriculture Organization of the United Nations. The development of the development zone, roads, a...
