Example 1:
the example is carried out at Wuwei oasis agricultural test station of agricultural academy of sciences of Gansu province, altitude is 1504 m, frost-free period is about 150 d, annual rainfall is 150mm, annual evaporation capacity is 2021mm, annual average air temperature is 7.7 ℃, sunshine hours are 3023 h, effective accumulated temperature is 3016 ℃ at the temperature of not less than 10 ℃, and total annual solar radiation is 140-2Belongs to the typical continental drought climate with insufficient two seasons and one season with residual temperate zone. The soil type is calcareous desert irrigation soil.
The test nitrogen fertilizer is urea, the phosphate fertilizer is triple superphosphate, and the total fertilization amount is pure N225 kg hm-2,P2O5 120 kg﹒hm-2. The phosphate fertilizer and 70 percent of the nitrogen fertilizer are used as base fertilizers and are spread on the ground surface before sowing, and the base fertilizers are turned into soil; the rest of the nitrogen fertilizer is used as additional fertilizer and is applied during the first irrigation.
Spring wheat variety Ningchun 53, seeding No. 3, month 13, seeding with a seed size of 450 kg. Hem.-2Drill seeding is adopted, and the row spacing is 15 cm.
The seed variety is Tukumame seed with seeding rate of 60kg-2Uniformly spreading the mixture in a field of spring wheat in 28 afternoon in 6 months (namely before the spring wheat is irrigated with yellow water), and irrigating in 29 morning in 6 months by flooding with water of 900m3﹒hm-2。
Harvesting the wheat in 14-day spring in 7 months, and setting the stubble height of 10cm, 25cm and 40cm 3 during harvesting.
Irrigating in 7 months and 15 days, wherein the irrigation mode is large water flood irrigation, and the irrigation amount is about 750m3﹒hm-2. Then, the water is irrigated respectively for 8 months and 5 days and 8 months and 25 days, the irrigation modes are large water flood irrigation, and the irrigation quantity is about 900m3﹒hm-2。
The stubble-remaining spring wheat straw and the hairy vetch are mixed and pressed for 9 months and 15 days, the pressing depth is 5-30cm, and the shearing length of the spring wheat straw and the fresh grass of the hairy vetch is 5-15cm during pressing.
Performing winter irrigation in 12 months and 8 days in a manner of flood irrigation with water amount of about 900m3﹒hm-2。
Second year, when the corn is planted in the single field, the variety is Wuke No. 2, and is planted in wide and narrow rows with a planting density of 82500. mu.m, and the narrow row is 40cm, the wide row is 60cm, and the planting density is 82500-2。
The test nitrogen fertilizer was urea, with the total amount of nitrogen applied after leaving the field as pure N420 kg @-2,The total nitrogen application amount of the spring wheat straw and the hairy vetch in the synergistic returning process is pure N345 kg-2,The fertilization mode is that 20 percent of each treatment is used as base fertilizer, 40 percent of additional fertilization is carried out in the jointing stage, and 40 percent of large bell mouth is adopted.
The phosphorus fertilizer used in the test is triple superphosphate, and the phosphorus application amount in all treatments is the same and is P2O5 120 kg﹒hm-2And is applied once as a base fertilizer.
All the field management measures such as irrigation treatment and the like are the same.
When the stubble-remaining spring wheat straws and the hair vetch are mixed and turned over in 15 days in 9 months, a nylon mesh bag burying method is adopted to determine the synergistic field returning decomposition rate of the spring wheat straws and the hair vetch.
The specification of the nylon mesh bag (120 meshes) is (35 cm multiplied by 25 cm), the loading amount of the straws in the mesh bag is converted according to the total amount and the area of the straws in the cell, the spring wheat straws and the fresh vetch grass are fully and uniformly mixed when being loaded, then the mixture is buried in a test field, the buried depth is 5-30cm, and the shearing length of the spring wheat straws and the fresh vetch grass is similar to the operation of the field and is 5-15 cm.
Sampling every 30 days after embedding, pouring out the spring wheat straws and the hairy vetch in the nylon mesh bag after sampling, washing, drying and weighing, and finally determining the straw decomposition rate by using a weight loss method.
As shown in figure 1, after the spring wheat straws and the vetch are returned to the field cooperatively, the yield of the spring corn grains is improved by 8.72-13.26% compared with that of the spring corn grains which are not returned to the field under the condition that the application amount of a chemical nitrogen fertilizer is reduced by 17.86% in the production process of the corn in the next season, and the difference reaches a remarkable level; compared with the traditional stubble remaining and returning (stubble remaining 10 cm), the method improves the treatment by 4.14-8.49%, wherein the difference between the stubble remaining height of spring wheat straws of 25cm and 40cm reaches a remarkable level.
As shown in figure 2, the decomposition rate of the spring wheat straw and the hairy vetch after being returned to the field cooperatively after 180 days is improved by 13.72-27.13% compared with the traditional spring wheat stubble remaining and returning to the field, wherein the spring wheat straw stubble height of 25cm and the decomposition rate of the spring wheat straw after being treated by 40cm reach a significant level compared with the traditional stubble remaining and returning to the field (stubble 10 cm).
Table 1 shows the C/N of spring wheat straw with different stubble height and the hairy vetch in cooperation with returning to the field.
As shown in Table 1, when the spring wheat straw and the hair vetch are returned to the field cooperatively, the carbon-nitrogen ratio can be adjusted by utilizing the carbon-nitrogen coordination of the spring wheat straw and the hair vetch, and the problem of imbalance of the carbon-nitrogen ratio when the spring wheat straw is returned to the field independently is solved. In the example, the carbon-nitrogen ratio of the traditional spring wheat straw returning to the field alone (stubble remaining by 10 cm) is 66.26, while the carbon-nitrogen ratios of the spring wheat straw returning to the field by 10cm +, 25cm + and 40cm + and the spring wheat straw returning to the field cooperatively with the hairy vetch are respectively reduced to 17.44, 23.48 and 28.61.
Table 2 shows the effect of the co-returning of spring wheat straw and hairy vetch on the nutrients of the topsoil (0-20 cm).
As shown in Table 2, the spring wheat straw and the vetch are returned to the field cooperatively, so that the soil fertility can be improved. Before the spring corn is sowed in the next year, the spring wheat straw and the hair vetch are returned to the field to process the organic matter, the alkaline hydrolysis nitrogen, the quick-acting phosphorus and the quick-acting potassium of the plough layer soil (0-20 cm) are improved, and compared with the field not returning process, the organic matter, the alkaline hydrolysis nitrogen, the quick-acting phosphorus and the quick-acting potassium are respectively improved by 8.22-10.04%, 10.18-16.98%, 22.80-29.49% and 17.81-28.71%, and compared with the traditional straw stubble remaining and field returning process, the organic matter, the alkaline hydrolysis nitrogen, the quick-acting phosphorus and the quick-acting potassium are respectively improved by 0.45-2.13%, 1.20-.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
