Problems solved by technology

However, this technology has strong regional and pertinence at the same time. Most of the research on this technology at home and abroad is carried out around winter wheat. The research and development achievements obtained cannot be applied to other crops in arid areas such as spring wheat and malting barley. Production
[0005] Therefore, aiming at the current situation of severe water shortage in arid areas and backward irrigation methods and low water use efficiency in actual crop production, the present invention provides a water-saving cultivation method for crops in arid areas

Embodiment 1

[0018] After soil preparation and fertilization, use a spring wheat ridge planter for ridge planting. The ridge width is 75cm, of which the ridge surface width is 50cm, the ridge width is 25cm, and the ridge height is 20cm. The ridge surface is sown with 4 rows of wheat with a row spacing of 13-15cm. The planting density is 450,000 to 500,000 seeds / mu. The suitable irrigation quota during the growth period of spring wheat is 200 cubic meters / mu, and the suitable irrigation frequency is 4 times, which are carried out on three leaves of spring wheat, flag picking, 10 days after heading, and 25 days after heading. The corresponding irrigation amount is 40 cubic meters / mu. Mu, 60 square meters / mu, 60 square meters / mu, and 40 square meters / mu. Irrigation is required to not flood the ridges; 12 kg of pure nitrogen and 10 kg of pure phosphorus are applied per mu, all phosphorus fertilizers are used as base fertilizer, and 70% nitrogen fertilizer is used as base fertilizer. 30% topdres...

Embodiment 2

[0020] After soil preparation and fertilization, the spring wheat ridge planter is used to complete the ridge and planting operations at one time. The ridge width is 78cm, of which the ridge width is 45cm, the ridge width is 33cm, and the ridge height is 19cm. The rest is the same as in Example 1. Compared with the traditional flat cropping method, the hydroponic cultivation method can increase the yield of spring wheat by 7.18% to 34.97%, increase the water use efficiency by 4.26% to 33.10%, and save more than 50 cubic meters of water per mu.

Embodiment 3

[0022] After soil preparation and fertilization, the beer barley ridge planter is used to complete the ridging and planting operations at one time. The ridge width is 75cm, of which the ridge width is 50cm, the ridge width is 25cm, and the ridge height is 20cm. 4 rows of barley are sown on the ridge surface with a row spacing of 13~ 15cm. The seeding rate is 350,000 to 400,000 seeds per mu. During the growth period of beer barley, the suitable irrigation quota is 180 cubic meters / mu, and the suitable irrigation frequency is 3 times, which are carried out during jointing, flag-raising, and grouting phases. The corresponding irrigation amounts are 50 cubic meters / mu, 70 cubic meters / mu, and 60 cubic meters. Square / mu. It is required that the ditch is not flooded during irrigation; 8-10 kg of pure nitrogen and 6-8 kg of pure phosphorus are applied per mu. All fertilizers are used as base fertilizer and no top dressing is applied. The specific irrigation frequency, irrigation quo...

Abstract

The invention belongs to the field of water-saving crop cultivation, in particular to a water-saving cultivation method of ridge planting and furrow irrigation for spring wheat and brewing barley in arid irrigation areas, which comprises the following steps of: (1) ridging and sowing: ridging according to the specifications that the ridge face width is 45-50 cm, the ridge furrow width is 25-33 cm and the ridge height is 15-20 cm; and sowing on the ridge face according to the specifications that the line distance is 13-15 cm and the sowing quantity is 0.5 million / mu; (2) furrow irrigation: carrying out irrigation by using the ridge furrows according to the requirement that the water in the furrows can not come up to the ridges, wherein the irrigation period and the irrigation times are same to those of the traditional method. Compared with the irrigation quantity of the traditional method, the irrigation quantity is reduced by 50-100 m<3> / mu. The water-saving cultivation method of ridge planting and furrow irrigation for spring wheat and brewing barley in arid irrigation areas is proposed aiming at the current status of severe water shortage in the arid irrigation areas and backward irrigation manner and not high water utilization efficiency in the traditional spring wheat and brewing barley production, and has the advantages of increasing the water utilization efficiency, saving the irrigation water and increasing the yield.

Description

Technical field [0001] The invention belongs to the field of water-saving cultivation of crops, and specifically relates to a ridge planting and furrow irrigation water-saving cultivation method used for the production of spring wheat and beer barley in arid irrigation areas. Background technique [0002] Crop production in most arid regions of my country is restricted by the local arid climate characteristics and severe water shortages. For example, the most important crops in agricultural production in the Hexi Oasis Irrigation Area of ​​Gansu, including important food crops spring wheat and malting barley for beer production, The local arid climate characteristics and severe water shortage have become key factors restricting crop production in these arid regions. Therefore, the research and development of new water-saving agricultural technologies is vital to the sustainable development of agriculture in arid regions. [0003] At present, the traditional flat cropping method has...
