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, the spring wheat ridge planter was used for ridge sowing. The ridge width was 75 cm, of which the ridge surface width was 50 cm, the ridge width was 25 cm, and the ridge height was 20 cm. 4 rows of wheat were sown on the ridge surface with a row spacing of 13-15 cm. The sowing density is 450,000 to 500,000 grains / mu. The suitable irrigation quota during the growth period of spring wheat is 200 m3 / mu, and the suitable irrigation times are 4 times, which are carried out respectively at the spring wheat three leaves, pick flags, 10 days after heading and 25 days after heading, and the corresponding irrigation volumes are 40 m3 / mu. Mu, 60m3 / mu, 60m3 / mu and 40m3 / mu, the irrigation furrows should not be flooded when irrigation; 12 kg of pure nitrogen and 10 kg of pure phosphorus should be applied per mu, and all phosphorus fertilizers should be used as base fertilizer, and 70% of nitrogen fertilizer should be used as base fertilizer. ...

Embodiment 2

[0020] After the fertilization of the site preparation, the spring wheat ridge planting machine is used to complete ridging and sowing in one go. The ridge width is required to be 78cm, wherein the ridge surface is 45cm wide, the furrow width is 33cm, and the ridge height is 19cm. All the other are the same as in Example 1. Compared with the traditional flat cultivation method, the hydroponics 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, use the beer barley ridge planter to complete the ridge and sowing operations at one time. The ridge width is required to be 75cm, of which the ridge surface width is 50cm, the ridge width is 25cm, and the ridge height is 20cm. 4 rows of barley are sown on the ridge surface, and the row spacing is 13~ 15cm. The seeding rate is 350,000 to 400,000 grains per mu. The suitable irrigation quota during the growth period of malting barley is 180 cubic meters / mu, and the suitable irrigation times are 3 times, which are carried out in the jointing, flag raising and grouting stages respectively. The corresponding irrigation volumes are 50 cubic meters / mu, 70 cubic meters / mu, 60 square / mu. When irrigated, it is required that the irrigation ditch is not full of ridges; 8 to 10 kg of pure nitrogen and 6 to 8 kg of pure phosphorus are applied per mu, and all fertilizers are used as base fertilizer, and no top dressing is applied. The specif...

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 in particular relates to a water-saving cultivation method for ridge farming and furrow irrigation for the production of spring wheat and malting barley in arid irrigation areas. Background technique [0002] The crop production in most arid regions of my country is restricted by local arid climate characteristics and serious shortage of water resources. For example, the most important crops in agricultural production in the oasis irrigation area in Hexi, Gansu include spring wheat, an important food crop, and malting barley for beer production. The local arid climate characteristics and the serious shortage of water resources have become the key factors restricting the crop production in these arid areas. Therefore, research and development of new water-saving agricultural technologies is crucial to the sustainable development of agriculture in arid regions. [0003] At prese...
