Embodiment 1

[0019] The following steps can be used to achieve zero irrigation and planting of crops in the North China Plain:

[0020] (1) Before the rainy season or before the snow season, carry out deep ploughing and soil preparation of the powder ridge, the depth of the powder ridge is 40-60 cm, and it is reserved.

[0021] (2) According to the local crop planting habits, select suitable crops, and plant the crop seeds after traditional water soaking and accelerating germination. The seeding rate is required to increase by 10%-20% compared with the traditional irrigation planting rate, and the seeding depth is increased by 1-3 cm. Then cover the soil.

[0022] (3) Field management implements zero irrigation, using local natural rainfall to naturally infiltrate the soil. The fertilization of crops refers to the conventional fertilization method, but should be combined with field cultivation or fertilization before rain.

[0023] (4) After harvesting at the right time, according to the local crop p

Embodiment 2

[0025] The following steps can be used to achieve zero-irrigation planting of wheat and corn on the ridges of the North China Plain:

[0026] (1) Carry out deep ploughing and soil preparation of powder ridges before it snows in October, the depth of powder ridges is 40-60 cm, and set aside.

[0027] (2) The wheat seeds are subjected to traditional water soaking to accelerate germination, and then sown in a good plot of powder ridges. The sown amount of wheat seeds is 10%-20% more than that of irrigated planting, and the sowing depth is increased by about 2 cm.

[0028] (3) Field management implements zero irrigation, and uses local natural rainfall to naturally infiltrate the soil. Fertilization of wheat refers to conventional fertilization methods, and fertilizers are applied before cultivating or rain.

[0029] (4) After the wheat is harvested from late May to early June, use tractors or powder ridge machines to carry out rotary tillage at a depth of 10-20 cm, and then sown corn seeds a

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.
