Smash-ridging zero irrigation planting method for crops

Abstract

A smash-ridging zero irrigation planting method for crops comprises the planting steps that (1) deep tillage smash-ridging soil preparation is performed before the rainy season or the snow reason, andthe smash-ridging depth is 40-60 cm; (2) a suitable crop is selected according to the local crop planting habit; crop seeds are sowed after undergoing conventional soaking and pregermination treatment; it is required that the seed sowing rate is increased by 10%-20% in comparison with the sowing rate of conventional irrigation planting, and the sowing depth is increased by 1-3 cm in comparison with that of conventional irrigation planting, and then, covering with soil is performed; (3) zero irrigation is executed during field management; local natural rainfall naturally permeates into the soil; and fertilizers are applied with reference to a conventional fertilizer applying method, while the fertilizers should be applied before intertillage or before the rain; and (4) after timely harvesting, according to the local crop planting period, crops are planted for 2-3 crops by a sowing and field management technology after minimum tillage of a parcel or with zero tillage. According to the method, ultra-deep tillage and subsoiling smash-ridging cultivation is employed, and normal growth and development and normal maturing and harvesting under the zero irrigation condition are guaranteedby the matched seed soaking and pregermination technology, seed sowing rate proper increasing technology and sowing depth proper increasing technology.

Description

Technical field [0001] The invention relates to the technical field of crop planting, in particular to an ecological planting method of crop powder ridges with zero irrigation for years. The technology is mainly applied to water scarce areas such as the North China Plain. Background technique [0002] The North China Plain is an important part of the Great Plains of Eastern China. Also known as Huanghuaihai Plain. It is located at 32°~40° north latitude and 114°~121° east longitude. It reaches the southern foot of Yanshan Mountain in the north, Dabie Mountain in the north, Taihang Mountain and Funiu Mountain in the west, Bohai Sea and Yellow Sea in the east, and spans 7 provinces and cities of Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, and Jiangsu, covering an area of ​​300,000 square kilometers. [0003] The rainfall in the North China Plain is not sufficient, with an annual rainfall of 500 to 900 mm. Precipitation in the Hengshui area of ​​central and southern Hebei Prov...

Problems solved by technology

For example, using traditional techniques to plant crops in the North China Plain, it is difficult to meet the growth needs of crops due to insufficient rainfall, and artificial irrigation is required; however, artificial irrigation of crops in the North China Plain requires a lot of manpower and material resources. Therefore, a Crop planting technology that reduces artificial irrigation
