Application of slow-release fertilizer: increase corn input-output ratio
Jinzhengda's slow-release fertilizer test demonstration was carried out on three middle and western counties (districts) in Jilin Nong'an, Dongfeng and Yubei, showing a good input-output ratio.
Nong'an input-output ratio 1:8.2
Jinzhengda controlled release fertilizer (23-8-8), compound fertilizer (15-15-15), compound fertilizer (28-15-12), potassium chloride (60%), diammonium (18-) 46).
For the benefit analysis of the demonstration area, the agricultural and agricultural Jinzheng large controlled release fertilizer is calculated at 2800 yuan per ton, the compound fertilizer is calculated at 3300 yuan per ton, and the corn is calculated at 2.0 yuan per kilogram, then the demonstration area ratio of Shijinzheng large controlled release fertilizer is In the custom fertilization area, the income per mu increased by 51 yuan, the input-output ratio of the demonstration area was 1:8.2, and the input-output ratio of the custom fertilization area was 1:11.5.
Dongfeng input-output ratio 1:11.1
Dongfeng selected Jinzhengda controlled release fertilizer (25-7-9), large granular urea (46%), small granular urea (46%), diammonium phosphate (18-46), potassium chloride (60%) .
Jinzhengda controlled release fertilizer in Nanxun Town, Dongfeng County is calculated at 2,951 yuan per ton, urea is calculated at 2,200 yuan per ton, diammonium is calculated at 3,400 yuan per ton, potassium chloride is calculated at 3,400 yuan per ton, and corn is calculated per kilogram. For the calculation of 2.0 yuan, the demonstration area of ​​Shi Jinzheng's slow-release fertilizer is 24.7 yuan more than that of the custom fertilization area, the input-output ratio of the demonstration area is 1:11.1, and the input-output ratio of the custom fertilization area is 1:16.3.
æ´®North input-output ratio 1:8.24
Jinzhengda controlled release fertilizer (20 -10 -10), compound fertilizer (15-15-15) and compound fertilizer (15-20-10) were selected in North Fujian. The results of the fertility traits of Yinong 14 corn showed that the plant height and stem diameter of Jinzhengda slow-release fertilizer as the base fertilizer were better than the soil-measuring formula fertilization treatment and the local farmers' customary fertilization treatment.
The weight of controlled release fertilizer in Weibei Jinzheng is calculated at 3,000 yuan per ton, the compound fertilizer is calculated at 2800 yuan per ton, the urea is calculated at 2000 yuan per ton, and the corn is calculated at 1.8 yuan per kilogram. The demonstration area of ​​Jinzhengda slow controlled release fertilizer is Compared with the custom fertilization area, the income increased by 53.4 yuan, the input-output ratio of the demonstration area was 1:8.24, and the input-output ratio of the custom fertilization area was 1:9.5.
The experiment showed that the corn yield increased by 6.24%, and the farmers were willing to accept the controlled release fertilizer. From the summary of the yield of the demonstration area, the average yield of the controlled release fertilizer of Jinzhengda is 813.8 kg/mu, and the customary fertilization output of the farmers is 766 kg/mu. The positive control release fertilizer of Jinzheng is 47.8 kg per mu. Increased production by 6.24%.
The trial and demonstration of Jinzhengda slow-release fertilizer through three counties (districts) showed that the application of Jinzhengda slow-release fertilizer had a certain yield-increasing effect on corn crops. One-time application means labor saving, labor saving and money saving. The phenomenon of fat, farmers are willing to accept.
