Embodiment

[0049] The experiment was carried out on the silt soil block of Xuanzhuang Village, Daolang Town, Daiyue District, Shandong Province. The soil in the 0-20cm soil layer of the test field contains 11.5g kg of organic matter -1 , total nitrogen 1.29g kg -1 , containing 93.09, 45.49, and 142.62mg kg of alkaline nitrogen, available phosphorus, and available potassium, respectively -1 .

[0050] The winter wheat variety Shannong 29 and the summer maize variety Denghai 618 were selected. On the same plot, first-year winter wheat was planted on October 12, 2015, and harvested on June 15, 2016, and summer corn was planted on June 16, 2016, and harvested on October 1, 2016. The second year of winter wheat was sown on October 3, 2016 and harvested on June 9, 2017, and summer corn was sown on June 11, 2017 and harvested on October 5, 2017. In the third year, winter wheat was sown on October 13, 2017 and harvested on June 8, 2018. Summer corn was sown on June 10, 2018 and harvested on ...

Abstract

The invention discloses a winter wheat and summer corn scarifying, ridging, laminating and micro-irrigation water and fertilizer integrated cultivation method which includes the steps: performing water-saving tillage operation on soil before winter wheat sowing, sequentially performing water-saving sowing operation and water and fertilizer management during growth of winter wheat, and crushing andreturning straws after winter wheat harvesting; sowing a line of corns on each of two sides of each ridge, performing deep furrow application of base fertilizers; performing corn season water management by a demand-based supplemental irrigation method; crushing and returning straws after corn harvesting. Fertilizer application rate is determined according to soil texture, the major nutrient content of an arable layer and target corn yield. Tillage water saving, coverage water saving, facility water saving and agronomic water saving are integrated, the advantage of integrated innovation is highlighted, the cultivation target of drought resistance, water saving, simplifying and high efficiency is achieved, economic, social and ecological benefits are remarkable, and the method has a wide popularization and application prospect.

Description

technical field [0001] The invention relates to the technical field of crop farming and cultivation, in particular to a winter wheat-summer corn plowing, ridging, film-covering, micro-irrigation, water and fertilizer integrated cultivation method. Background technique [0002] The problems of low natural precipitation, water shortage, poor soil fertility and per capita arable land reduction in China's arid areas have seriously restricted the increase in unit yield and total yield of grain crops such as wheat, corn, and millet, threatening national food security. In many places in arid regions, the average annual evaporation is 4-8 times the average annual precipitation, and unreasonable farming methods will further increase the evaporation loss of soil water, resulting in a decrease in soil water storage and a sharp decline in farmland productivity. In some areas with irrigation conditions, the irrigation methods are backward and the water and fertilizer management is extens...
