Embodiment 1
[0037] By adopting the method of the present invention, a field test was carried out in Jingmen City, Hubei Province in May 2013, in which all the fertilizers in the root zone of rice were applied in one-time holes and conventional three-time sprinkling for comparison. The area of the community is 40m 2 , the density is 14,700 plants / mu, the row spacing is 24cm, and the plant spacing is 19cm. The amount of phosphorus and potassium fertilizers in each treatment was the same, and the phosphorus fertilizer was 6kg / mu (P 2 o 5 ), potassium fertilizer 8kg / mu (K 2O). There are 2 dosages of nitrogen fertilizer in this test, one is the local customary dosage of 15kg / mu (N), and the other is a reduction of 11kg / mu (N). Seven treatments are set according to the amount of N and the way of application, namely: N15 Sowing (N dosage is 15kg / mu, divided into three times according to the conventional 4-3-3 ratio), N11 sowing (N dosage is 11kg / mu, according to the conventional 4-3-3 rati...
Embodiment 2
[0040] Used in Guangde County, Anhui Province in May 2014 15 N isotope-labeled fertilizers were used in a field experiment comparing one-time hole application to the rice root zone and conventional three-time application. Three treatments were set up in the test: conventional fertilization (spreading in 4-3-3 stages), one-time hole application (the location of hole application was 5 cm from the root and 10 cm deep), and a control treatment without nitrogen fertilizer application. The amount of phosphorus and potassium in each treatment is consistent, and the amount of nitrogen fertilizer in the plots treated with nitrogen application is also equal. The amount of nitrogen, phosphorus and potassium fertilizers is respectively: N 15kg / mu, P 2 o 5 6kg / mu, K 2 O 8kg / mu.
[0041] The result shows (as shown in table 1), the processing yield difference of all fertilizers one-time hole application and conventional 3 times application is not significant, but can find out by comparin...
Embodiment 3
[0047] It was used in Jiangyan City, Jiangsu Province in May 2014 15 N isotope-labeled fertilizers were used in a field experiment comparing one-time hole application to the rice root zone and conventional three-time application. Three treatments were set up in the test: conventional fertilization (spreading in 4-3-3 stages), one-time hole application (the location of hole application was 5 cm from the root and 10 cm deep), and a control treatment without nitrogen fertilizer application. The amount of phosphorus and potassium in each treatment is consistent, and the amount of nitrogen fertilizer in the plots treated with nitrogen application is also equal. The amount of nitrogen, phosphorus and potassium fertilizers is respectively: N 15kg / mu, P 2 o 5 6kg / mu, K 2 O 8kg / mu.
[0048] The result shows (as shown in table 2), and all fertilizers one-time hole application compares with the processing of conventional 3 application, increase production 64.8kg / mu, and yield rate re...
