Environment-friendly drop irrigation water-saving cultivation method for winter wheat/summer maize crop rotation system

Abstract

The invention relates to an environment-friendly drop irrigation water-saving cultivation method for a winter wheat / summer maize crop rotation system. A winter wheat / summer maize planting spacing anddrop irrigation belt arrangement mode is developed, a water and fertilizer integrated implementation scheme for water conservation and fertilizer saving of the winter wheat / summer maize crop rotationsystem is built, and different agricultural water saving methods, drop irrigation platform automatic control systems, precise positioning tractors and multifunctional all-in-one machines are also used, so that an environment-friendly drop irrigation water-saving cultivation technology for the winter wheat / summer maize crop rotation system suitable for north China plain is formed. The water and fertilizer utilization efficiency is improved, the irrigation cost is reduced, and the effects of increasing the yield and improving the efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a green drip irrigation and water-saving cultivation method for winter wheat / summer corn rotation system, especially to provide a low-cost, low-pollution, high-efficiency and high-efficiency cultivation for winter wheat / summer corn rotation areas in the North China Plain method. Background technique [0002] Winter wheat / summer maize double-cropping rotation system is the main grain planting method in the Huanghuaihai region of North China. However, due to the shortage of water resources in North China and the serious situation of groundwater overexploitation, agriculture is the main groundwater user in shallow groundwater overexploitation areas. The lack of water during the crop growth period leads to a decline in yield, which seriously affects my country's food security. With the increase of population, the reduction of arable land, the acceleration of urbanization, factors...

Problems solved by technology

However, the planting crops are limited to corn, which cannot satisfy the good combination of two-crop planting and drip irrigation technology in the winter wheat / summer corn rotation system in the North China Plain, that is, the matching of planting row spacing and capillary spacing, and the impact of tillage on capillary tubes. input, increased production costs

Such as Shihezi University Liu Jianguo and others invented "a double-drip cultivation method for re-sowing crops with wheat stubble drip irrigation belt" (public number: CN104663223A), which describes in detail the treatment method of replanting wheat after harvesting using drip irrigation technology, and realizes the drip irrigation belt. The secondary utilization of the technology enables the "double-drop" cultivation of successive crops, reduces production costs, and improves the multiple cropping index and the utilization rate of water and fertilizer resources. The nature and water and fertilizer management methods are not clear, which greatly affects the benefits of drip irrigation, water saving and fertilizer saving.
