AI Technical Summary

Problems solved by technology

With the gradual improvement of the country's key water conservancy projects, major floods and waterlogging have been better controlled, but the wide-ranging, large-scale, and severe waterlogging disasters have not been effectively curbed, resulting in an average annual grain output loss of 11.03%; Waterlogging disasters are particularly prominent in low-lying flood storage areas and last for a long time. Under the traditional wheat-soybean (jade) model, the yield loss of soybeans and corn due to disasters is as high as 24.2%.
The mechanization and low degree of simplification of traditional waterlogging prevention and control technologies are difficult to popularize and apply, and the new technologies are mostly single technologies with little application effect, resulting in poor production stability and low yields of crops along the Huaihe River. Huai farmers increase production and income

Embodiment 1

[0059] Enhancing waterlogging resistance performance of winter wheat by adjusting seeding density

[0060] The applicant has carried out in-depth research on the influence of different densities of Wanmai 52 on wheat population regulation and comprehensive waterlogging resistance through multiple points for many years.

[0061] The specific time cultivation method is 150, 225, 300, 3.75 million / hm 2 The basic seedling YRIR was planted experimentally in Anhui according to the above method for winter wheat.

[0062] The specific process of the wheat planting adopted in the present embodiment is as follows:

[0063] Step 1. The sowing of wheat needs to adopt the method of sowing after plowing and plowing, so base fertilizer is added before plowing and plowing, and the land plowing is carried out by using a rotary tiller or a plow matched with a tractor. Rotary tillage enables the fertilizer to be buried in the soil and evenly combined with the soil; after two consecutive years ...

Embodiment 2

[0077] Improving waterlogging resistance of winter wheat through nitrogen fertilizer operation

[0078] In addition, the applicant has carried out research on improving the waterlogging resistance of winter wheat by planting Wanmai 52 and Fanmai 5 with different nitrogen fertilizer management methods in different plots for many years.

[0079] The planting method in this embodiment is similar to that in Embodiment 1, except that in this embodiment, different topdressing methods are adopted for different plots.

[0080] The test results are shown in Table 7. It can be seen from the table that Wanmai 52 adopts different base topdressing ratios (base nitrogen: topdressing nitrogen at the jointing stage are 10:0, 5:5, and 3:7 respectively) nitrogen fertilizer operation methods, and waterlogging Under the same conditions, their YRIRs were 19.65%, 13.70%, and 17.36%, respectively; the YRIRs of Panmai No. 5 were 20.39%, 16.01%, and 16.83%, respectively (Table 2). It can be seen that...

Embodiment 3

[0085] The applicant adopts (1) the planting method of the present invention and (2) the traditional sowing method of "plowing, fertilizing, and spreading with large amount of seeding" and the "one-bombing" fertilization method respectively in adjacent soil plots of the same quality. Tested against waterlogging. Below, the applicant will give the waterlogging resistance data under various planting methods. RIR in the table represents the difference in relative injury rate.

[0086] Comparison of the effect of winter wheat "reduced density, strong group, average nitrogen and strong plants" anti-waterlogging cultivation and traditional technology

[0087] In the present embodiment, the specific process of the wheat planting adopted in the present embodiment is as follows:

[0088] Step 1. The sowing of wheat needs to adopt the method of sowing after plowing and plowing, so base fertilizer is added before plowing and plowing, and the land plowing is carried out by using a rotar...

Abstract

The invention discloses a winter wheat downgrade uniform nitrogen waterlogging and waterlogged resistance cultivation method. By comparing the downgrade population healthy uniform nitrogen plant firming waterlogging and waterlogged resistance cultivation technology (optimal plant firming waterlogging and waterlogged resistance nitrogen operation mode of precision uniform sowing mode of 'strip sowing integration of a rotary tillage and fertilizing machine' and balanced base fertilizer and additional fertilizer (base nitrogen: additional nitrogen=5:5) through 'protecting the base fertilizer andincreasing the additional fertilizer') with a traditional cultivation technology (a traditional sowing mode of 'ploughing, spreading fertilizer, sowing in large quantities by spreading' and a fertilization method of 'fertilizing concentratedly'), the experiment result shows that the downgrade population healthy uniform nitrogen plant firming waterlogging and waterlogged resistance cultivation technology facilitates cultivating strong seedlings and establishing a reasonable population, the defects of large sowing quantity, and easy lodging of a large population in the prior art are overcome,the root activity and rooting force of the winter wheat are enhanced, the waterlogging and waterlogged resistance capability of the winter wheat is improved, and waterlogging and waterlogged hazard ofthe winter wheat in the middle and later periods can be obviously reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to the field of anti-waterlogging cultivation technology of winter wheat in the Huanghuaihai region. Background technique [0002] The Huaihe River Basin involves 5 provinces of Hubei, Henan, Anhui, Sulu, with a land area of ​​about 270,000 km 2 , the total arable land area accounts for nearly 1 / 7 of the country, and the grain output and commercial grain output account for about 1 / 5 and 1 / 4 of the country respectively. It is an important production base of grain, cotton and oil in my country. The area along the Huaihe River refers to a large area of ​​low-lying plains distributed along the Huaihe River and some of its tributaries, including lakes, depressions, flood discharge areas, flood storage areas, flood detention areas, polders protected by dikes, and nearby farming areas along the Huaihe River and some of its tributaries. It is a geographical area with a width of 50-80km across the...
