Crop name: Qingsi dual-purpose corn
Address: Qianjin, Pingzhuang Town, Yuanbaoshan District, Chifeng City
Product dosage: The demonstration field is irrigated with 2 kilograms of Jinong Letu and 5 kilograms of urea per mu; Application of water-soluble fertilizer in the control field
Product effect:
Production testing will be conducted on September 7, 2023. The specific method is to select the corresponding positions of the demonstration field and the control field and continuously chop 5 seedlings, taking a total of 5 points, with 5 seedlings in each group and 25 seedlings in each group. Measure three sets of data, including plant height, total weight per plant, and corn cob weight. The data details are as follows:
1、 Plant height
Demonstration one, 2.73 meters control one, 2.25 meters
Demonstration two, 2.70 meters control two, 2.51 meters
Demonstration three, 2.89 meters, control three, 2.58 meters
Demonstration four, 3.01 meters control four, 3.02 meters
Demonstration five, 2.76 meters control five, 2.41 meters
The average height of the demonstration field is 2.806 meters, and the average height of the control field is 2.576 meters
2、 Total weight per plant
Demonstration 1, 9.32 pounds Control 1, 7.00 pounds
Demonstration 2, 7.32 pounds Control 2, 7.12 pounds
Demonstration three, 8.40 pounds, control three, 7.26 pounds
Demonstration Four, 10.60 kg Control Four, 10.24 kg
Demonstration 5, 8.08 pounds Control 5, 8.08 pounds
The average total weight per plant in the demonstration field is 1.748 kilograms, while the average total weight per plant in the control field is 1.588 kilograms
Based on an average of 4650 plants sown per mu, the total weight per mu increases yield by 744 kilograms.
3、 Weight of fresh corn cobs
Demonstration 1, 2.68 pounds Control 1, 1.32 pounds
Demonstration 2, 1.84 pounds Control 2, 1.92 pounds
Demonstration Three, 2.60 kg Control Three, 1.80 kg
Demonstration Four, 3.48 kg Control Four, 3.20 kg
Demonstration 5, 2.12 pounds Control 5, 2.20 pounds
The average weight of a demonstration stick with 25 sticks is 0.508 pounds per stick, while the average weight of a control stick with 27 sticks is 0.386 pounds per stick
The fullness and maturity of the corn cobs in the demonstration field are significantly higher than those in the control field. According to the base owner, the corn in such plots has high protein and starch content, and the high or low content of these two data directly affects the purchase price.
The above yield measurement data can indicate that after applying 2 jin of Jinong Letu on both green and feed corn, it has a significant effect on increasing yield and improving quality.
