Problems solved by technology

The main problems at present are: the planting area of ​​seed production corn is large, and the continuous cropping period is as long as 15 years. Due to the long continuous cropping period, the nutrient ratio in the seed production corn field is unbalanced, and physiological diseases of nutrient deficiency often occur; due to the long continuous cropping period, There are many soil-borne diseases, coupled with insufficient input of organic fertilizers, excessive application of chemical fertilizers, soil compaction, decreased organic matter content, weakened water storage function, and increased fertilization costs; the active ingredients and proportions of compound fertilizers circulating on the market do not meet the requirements of seed corn production. The field nutrient status and the absorption ratio of corn to nutrients, and it does not have the effect of water retention and soil improvement; resulting in a decline in the quality and yield of seed production corn, and some seed industry groups have flowed to Xinjiang, Inner Mongolia and Ningxia, affecting the viability of the seed production corn industry in this area. sustainable development

Embodiment 1

[0037] Example 1 A seed-producing corn field continuous cropping obstacle conditioner, the conditioner is composed of modified furfural slag, cow dung, 5406 bacterial fertilizer, water retaining agent, polyvinyl alcohol in a weight ratio of 39.94:59.92:0.06:0.05:0.03 (kg / kg) After mixing, it is obtained through harmless treatment.

[0038] The production method of the seed production cornfield continuous cropping obstacle conditioning agent comprises the following steps:

[0039] ⑴ Weighing according to the proportion;

[0040] (2) Mix modified furfural slag, cow dung, and 5406 bacterial fertilizer to obtain a mixture;

[0041] (3) Add CO(NH 2 ) 24.0~5.0kg, so that the C / N is 25:1; then add water to make the water content reach 50~55%, mix evenly, and fill it all in the pre-excavated depth of 2.5 meters, 2 meters wide, and 4~10 meters long Seal the pit with mud, stack and ferment for 140-150 days, then air-dry in a cool and dry place for 28-30 days to make the water...

Embodiment 2

[0042] Example 2 A seed-producing corn field continuous cropping obstacle conditioner, the conditioner is composed of modified furfural slag, cow dung, 5406 bacterial manure, water-retaining agent, and polyvinyl alcohol in a weight ratio of 37.95:61.96:0.04:0.04:0.01 (kg / kg) After mixing, it is obtained through harmless treatment.

[0043] The production method of the seed production cornfield continuous cropping obstacle conditioning agent is the same as Example 1 .

Embodiment 3

[0044] Example 3 A seed-producing corn field continuous cropping obstacle conditioner, the conditioner is composed of modified furfural residue, cow dung, 5406 bacterial fertilizer, water-retaining agent, and polyvinyl alcohol in a weight ratio of 42.94:56.93:0.05:0.06:0.02 (kg / kg) After mixing, it is obtained through harmless treatment.

[0045] The production method of the seed production cornfield continuous cropping obstacle conditioning agent is the same as Example 1 .

[0046] the above Example 1~3 Among them, modified furfural slag refers to adding 21.33~25.60kg (NH 4 ) 2 CO 3 , so that the pH value of furfural slag is 5.0~6.0, and the particle size obtained after sieving is 2~5 mm, containing 66~70% of organic matter, 49~64% of C, 0.50~0.61% of total N, and 0.30~0.36% of total P , modified furfural slag with full K 1.10~1.18%.

[0047] Cow dung comes from farms, with a particle size of 2-5 mm, containing 14.50% organic matter, 0.52% total N, 0.28% total ...

Abstract

The invention relates to a seed production cornfield continuous cropping obstacle conditioner. The conditioner is prepared by mixing modified furfural residue, cow dung, 5406 bacterial manure, water retaining agent and polyvinyl alcohol at a weight ratio of (37.95-42.94):(56.93-61.96):(0.04-0.06):(0.04-0.06):(0.01-0.03) and then performing harmless treatment. The conditioner provided by the invention not only promotes the resource recycling, but also solves the problems that the planting area of seed production corn is large, the continuous cropping time is long, the nutrient proportion of the seed production cornfield is unbalanced, many soil-borne diseases are caused, the soil is hardened, the organic content is reduced, the water storage function is weakened and the like, thereby achieving the aims of providing crop nutrition, improving the organic content of the soil, enhancing the water storage function of the soil and improving the soil structure.

Description

technical field [0001] The invention relates to the field of agricultural soil, in particular to an obstacle conditioner for continuous cropping in corn fields for seed production. Background technique [0002] Gansu Hexi Inland Irrigation District has unique natural conditions and location advantages, attracting more than 90 domestic and foreign companies including DuPont Pioneer, Monsanto, Denghai Pioneer Seed Industry, China Seed Industry, Liaoning Dongya, Beijing Denong, ORG, Dunhuang, etc. The seed industry group has established a corn seed production base of 1.5 million mu, accounting for 1.5 million mu. The corn seed production industry has developed into one of the important pillar industries for increasing farmers' income and increasing agricultural efficiency in Hexi inland irrigation areas. The main problems existing at present are: the planting area of ​​seed production corn is large, and the continuous cropping period is as long as 15 years. Due to the long cont...
