Embodiment 1

[0016] After soil preparation and fertilization, use a micro-ridge film mulcher to ridge, film, cover soil and pierce holes. The ridge width is 15 cm, the ditch width is 15 cm, and the ridge height is 10 cm. A row of wheat is planted on the ridge with an artificial hole planter. The hole distance is 12 cm, and each hole is 12- 15 grains, the sowing depth is 3-5cm, and the sowing density is 450,000-550,000 grains / mu. During the growth period of spring wheat, the suitable irrigation quota is 240 m3 / mu, and the suitable irrigation frequency is 3 times, and the irrigation time is 1 time at the jointing stage, tassering-flowering stage, and filling stage of wheat respectively, and the amount of water for each time is 80 m 3 / mu, when irrigation, it is required that the irrigation ditch does not flood the ridge; 12 kg of pure nitrogen and 8 kg of pure phosphorus are applied per mu, and all phosphorus fertilizers are used as base fertilizer, 70% of nitrogen fertilizer is used as base...

Embodiment 2

[0018] After soil preparation and fertilization, use the micro-ridge mulching machine to complete the work of ridge mulching, mulching, covering soil, and piercing holes. The ridge width is required to be 15 cm, the ditch width is 15 cm, and the ridge height is 10 cm. A row of beer barley is planted on the ridge with an artificial hole planter, and the hole distance is 12 cm. There are 5-8 grains in the hole, the sowing depth is 3-5cm, and the sowing density is 185,000-320,000 grains / mu. The suitable irrigation quota during the growth period of spring wheat is 240 m3 / mu, and the suitable irrigation frequency is 3 times, and the irrigation time is 1 time at the jointing stage, tasseling stage and grain filling stage of wheat respectively, and the irrigation volume is 80 m3 each time. 3 / mu, when irrigation, it is required that the irrigation ditch does not flood the ridge; 8 kg of pure nitrogen and 6 kg of pure phosphorus are applied per mu, all phosphorus fertilizer and 2 / 3 ni...

Embodiment 3

[0020] After soil preparation and fertilization, use a micro-ridge film mulcher to complete the work of ridge mulching, film covering, and soil pricking. It is required that the ridge width is 15cm, the ditch width is 20cm, and the ridge height is 10cm. 3-5 grains, sowing depth 2-3cm, sowing density 84,000-140,000 grains / mu. The suitable irrigation quota during the growth period of spring rapeseed is 120 m 3 / mu, the suitable irrigation times are 2 times, respectively, 1 time at the 5-6 leaf stage of rapeseed and moss flowering stage, each irrigation volume is 60 square meters / mu, and the irrigation furrows are required not to flood the ridges when irrigation; pure nitrogen 10 Kg, 8 kg of pure phosphorus, 2 kg of pure potassium, 1 kg of borax, phosphate fertilizer is applied as base fertilizer, 50% of nitrogen fertilizer is used as base fertilizer and seed fertilizer, and 50% is topdressed in furrows with head water. The specific irrigation frequency, irrigation volume and f...

Abstract

The invention relates to a crop cultivation method, in particular to a micro-ridge film-covering hole sowing water-saving cultivation method for closely planted crops in irrigation areas. The micro-ridge film-covering hole sowing water-saving cultivation method for the closely planted crops in the irrigation areas is characterized in that the yield-increasing mechanism adopting micro-ridge film-covering furrow irrigation, temperature rising, soil moisture preservation, rainwater harvesting and water saving is utilized, the moisture and fertilizer using efficiency is improved, agricultural microclimate is improved, a soil structure is changed, a photosynthesis environment is optimized, the production limitation problem caused by drought factors on the closely planted crops for a long time is effectively solved, and the yields of spring wheat, malting barley, oilseed rape and other closely planted crops are improved remarkably.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a method for cultivating densely planted crops in irrigation areas with micro-ridges and film-covered hole-sowing furrow irrigation and water-saving cultivation methods. Background technique [0002] Water resources are an important factor in agricultural production input, and in arid and semi-arid areas with limited precipitation, water resources and their utilization status are even more determinants of agricultural productivity. The shortage of water resources is a major resource and environmental problem faced by human beings. my country is one of the 13 countries with the poorest water resources in the world. [0003] At present, the traditional flat cultivation method has serious water waste after irrigation, and the utilization rate of water resources is not high. There have been a lot of research on water-saving technologies at home and abroad, such as water-saving tech...
