Embodiment 1

[0026] Example 1: Verification experiment on the influence of different fertilization methods on summer maize yield and its components

[0027] 1. Test site

[0028] The experiment was carried out at the Yuanyang Experimental Base of Henan Agricultural University from June 11, 2017 to September 28, 2017. The study area is located in the Northern Henan Plain, which has a warm temperate continental climate with four distinct seasons, an average annual temperature of 14.5°C, and an average annual precipitation of 573.5 mm. The soil used for the test is sandy fluvo-aquic soil, and the planting mode is wheat-corn rotation. The basic nutrient properties of the soil are shown in Table 1.

[0029] Table 1 Basic nutrient status of the tested soil

[0030] .

[0031] 2. Experimental design

[0032] The area of ​​the test plot is 29 m 2 , each treatment was repeated three times and arranged in random blocks. The test fertilizer is special fertilizer for summer corn (28-10-12) (pr...

Embodiment 2

[0047] Example 2: Verification of the effects of different fertilization methods on the aboveground biomass of summer maize

[0048] 1. The test site and test design are the same as in Example 1.

[0049] 2. Computational statistical methods

[0050] Aboveground biomass (kg / hm 2 ) = dry weight of corn stalks + dry weight of corn kernels

[0051] 3. Test results such as figure 1 shown.

[0052]Nitrogen application can increase the aboveground biomass of summer maize, and the dry matter weight of each nitrogen application treatment increased by 0.46%-21.40% compared with Z5 treatment, and the dry matter weight of Z1 was the highest at 16126.76 kg / hm 2 , the lowest in Z5, when the amount of fertilizer was the same, the dry matter weight of Z1 increased significantly by 20.65% compared with Z3, the dry weight of straw increased by 14.32%, and the dry matter weight of grain increased significantly by 25.96%; the dry matter weight of Z2 increased by 11.23% compared with Z4, of w...

Embodiment 3

[0053] Example 3: Verification test on the influence of different fertilization methods on the nutrient accumulation of summer maize plants

[0054] 1. The test site and test design are the same as in Example 1.

[0055] 2. Plant sample analysis

[0056] During the harvest period, 3 corn plants were randomly selected from each plot, the stalks were separated from the ears, and they were killed at 105°C for 15 minutes, and the temperature was adjusted to 65°C to dry to constant weight, and then the dry matter weight of the straws and grains were measured. h 2 SO 4 -H 2 o 2 Decoction, AA3 automatic flow injection analyzer to measure plant total nitrogen, molybdenum blue colorimetric method (880 nm) to determine plant total phosphorus, and flame photometry to determine plant total potassium.

[0057] 3. Computational statistical methods

[0058] Nutrient accumulation (kg / hm 2 ) = [dry weight of non-harvested material (kg / hm 2 ) × nutrient content of non-harvested material...

Abstract

The invention discloses a fertilizer-reducing synergistic fertilizing method for summer corns in a moisture soil area. In a corn planting season, when corn seeds are sown, basal application is carriedout by using a N fertilizer of 147-210 kg/hm<2>, a P2O5 fertilizer of 70-80 kg/hm<2> and a K2O fertilizer of 85-95 kg/hm<2>, wherein the N fertilizer is applied through a mode of right hole application, and the fertilizing depth is 10-15 cm. According to the fertilizing method disclosed by the invention, the fertilizing amount is reasonably reduced under the premise that stable yield and high yield of the corns are guaranteed, a purpose of high yield and high efficiency is achieved, the method is of a great significance to protecting environment, saving resources and increasing benefits, andhigh yield, high efficiency and simplified fertilization are realized.

Description

technical field [0001] The invention relates to the technical field of corn planting, in particular to a summer corn weight loss and efficiency fertilization method suitable for fluvo-aquic soil areas. Background technique [0002] Corn is one of the most important food crops in my country. China is the second largest producer and consumer of corn after the United States, with the largest planting area. The Huanghuai fluvo-aquic soil area is one of the main corn-producing areas in my country, and occupies a pivotal position in the contribution of corn production. With the rapid development of social economy, the living standard of residents has been improved, and the food consumption structure has also undergone corresponding changes, making the total demand for corn continue to increase. [0003] In the past 50 years, the increase in per unit yield has accounted for 84.9% of the increase in my country's total corn production, and the area is 15.1%. That is to say, the incr...
