Problems solved by technology

However, at present, there are few studies on the two-season stubble docking of pipe belt laying and fertilization system in the drip irrigation water and fertilizer integration technology of wheat and corn. In addition, the integration of water and fertilizer in summer maize also has the problem of low proportion of deep root system and easy lodging. To better realize the coordination and unification of water, fertilizer efficiency and high yield of annual planting of wheat and corn under the condition of drip irrigation. Therefore, taking the two crops of winter wheat, wheat and summer corn as a whole, the establishment of annual drip irrigation, water and fertilizer integration pipe laying mode and fertilization system is very important for highlighting the integration of water and fertilizer in wheat. The advantage of reducing weight and increasing efficiency in corn production and accelerating the promotion of water and fertilizer integration are of great significance

Embodiment 1

[0032] The present embodiment provides a kind of drip irrigation water and fertilizer integrated cultivation method of wheat stubble summer maize under a kind of concrete no-tillage direct seeding condition, comprises the following steps:

[0033] (1) When wheat is sown, carry out moisture-grabbing sowing or drip irrigation with small amount of water after sowing to emerge. The row spacing is 25cm, 11 rows per ridge, and the ridge width is 0.5m. Correspondingly, 4 drip irrigation pipes / belts are laid, and 1 pipe has 2-3 rows. Wheat, specifically, the 4 drip irrigation pipes / belts in each furrow include one drip irrigation for every 2 rows of wheat (except for the 5th-7th row from the left that lays a pipe / belt for 3 rows of wheat); then, in the wheat During the overwintering period, rising period, jointing period, flowering period, and grouting period of the growth period, when the water content of the 0-40cm soil layer is lower than 60% of the field water holding capacity, dri...

Embodiment 2

[0039] Under the condition of drip irrigation, the effect of pipe laying mode under the integration of drip irrigation, water and fertilizer on the nitrogen accumulation and distribution, soil nitrate nitrogen content and yield of summer maize was studied and explored. The test was set up to control one tube with one row (65cm equidistant row mode) and one tube with two rows (3 types): 40+90cm, 45+85cm, 50+80cm, drip irrigation pipes were laid in the middle of narrow rows. The results showed that nitrogen accumulation in the aboveground under the 45+85cm and 40+90cm one-tube-two-row patterns was significantly higher than that of the control and 50+80cm one-tube-two-row patterns at the maize maturity stage, which were 35.51% and 27.06% higher than the control, respectively; , the content of nitrate nitrogen from the surface to 40cm is the highest in the control model. The grain yield of 50+80cm, 45+85cm and 40+90cm was 42.31%, 28.00% and 14.56% higher than that of the control, ...

Embodiment 3

[0043] In the present invention, the nitrogen fertilization ratio is 40%: 30%: 20%: 10%, and the phosphorus fertilizer fertilization ratio is 40%: 30%: 20%: 10% in the corn sowing, corn big bell mouth stage, tasseling and silking stage, and grouting stage. , the ratio of potassium fertilizer application is 40%:40%:20%:0%. Adopting this specific fertilization plan has significant advantages. It increases the amount of seed fertilizer and nitrogen fertilizer appropriately, reduces the amount of topdressing fertilizer in the big bell-mouth stage, and can significantly increase the amount of corn fertilization. The root density of the deep soil can effectively improve the root structure, greatly increase the lodging resistance of corn plants, and significantly increase the yield of corn.

[0044] See attached figure 2 , 3 , under field drip irrigation conditions, explored the effects of different nitrogen fertilization systems on the root distribution and yield of summer maize un...

Abstract

The invention discloses a wheat stubble summer corn drip irrigation water and fertilizer integration cultivation method under a no-tillage direct-sowing condition. The method comprises the following steps of 1, planting wheat with equal line spacing, wherein 11 lines of the wheat are planted ever bed, and 4 drip irrigation pipes/belts are laid correspondingly; 2, removing 2 irrigation pipes/belts at intervals in every bed before the wheat is harvested, wherein the remaining 2 irrigation pipes/belts are used for water and fertilizer irrigation in a corn planting season; 3, adopting a wide and narrow line mode when corn is planted, wherein 4 lines of corn is planted every bed; 4, removing all the irrigation pipes/belts around the time when the corn is harvested, wherein cultivation preparation is conducted for wheat planting in the next season after the corn is harvested, and anniversary planting circulation is completed. The wheat stubble summer corn drip irrigation water and fertilizer integration cultivation method under the no-tillage direct-sowing condition can effectively solve the major problems that the wheat and corn main production area are short in water resource, low in water and fertilizer utilization efficiency, low in land productivity, low in labor productivity and the like, and has remarkable economic and social benefit.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to an integrated cultivation method of drip irrigation, water and fertilizer. Background technique [0002] The promotion and application of drip irrigation water and fertilizer integration for wheat and corn will help solve major problems such as water shortage, low water and fertilizer use efficiency, low land productivity, and low labor productivity in major wheat and corn producing areas, and will help further promote land transfer and reduce the cost of growing grain. The planting cost of large households and family farms is reduced, and farmers start their own businesses to become rich. The common drip irrigation water and fertilizer integrated system for wheat and corn in North China basically uses a pressure system to blend soluble solid or liquid fertilizers into a fertilizer solution according to the soil nutrient content and the characteristics and laws of crop fertil...
