Embodiment 1

[0018] Using nitrogen, phosphorus, potassium three factors quadratic D-saturation optimal design, through the field test in the Three Gorges reservoir area. The tested Dactylis species is the model Dactylis provided by Beijing Bailu Company, the germination rate is measured in the laboratory, and no treatment is done before sowing. The nitrogen fertilizer for testing is urea (N content is 46%), produced by China Nuclear Industry Jianfeng Chemical General Plant, and the phosphate fertilizer is superphosphate (P 2 o 5 Content is 12%) is produced by Luzhou Xingtai Phosphate Fertilizer Co., Ltd., potash fertilizer is potassium sulfate (K 2 O content is 25%), produced by Weifang Xidefeng Agrochemical Co., Ltd. The actual amount of fertilization in the test was expressed as pure N, P 2 o 5 and K 2 O equivalent calculation.

[0019] The test site is located in Fengdu County, Chongqing City. It is located at 107°28′03″-108°12′37″ east longitude, 29°33′18″-30°16′25″ north latitud...

Embodiment 2

[0026] The difference of N, P, and K contents in the dry matter of Dactylis chinensis under different treatment conditions was studied through the field experiment of balanced fertilization of Dactylis sativa, so as to clarify the influence of different fertilization treatments on the quality of Dactylis sativa. The test location and treatment are the same as in Example 1. The test results are as follows:

[0027] Table 2 Different experimental treatments and N, P, K contents

[0028]

[0029] As can be seen from Table 2, the amount of nitrogen fertilizer (urea) per unit area is 195kg / hm 2 , the amount of phosphate fertilizer (superphosphate) is 376kg / hm 2 , the dosage of potassium fertilizer (potassium sulfate) is 382kg / hm 2 The quality of Dactylis sativa was significantly higher than that of other treatments.

Abstract

A fertilizing method for orchard grass is characterized in that urea is taken as nitrogen fertilizer, calcium superphosphate is taken as phosphate fertilizer, and potassium sulfate is taken as potash fertilizer, wherein the use amount of nitrogen, phosphorus and potassium follows the proportion that N:P205:K20 by weight portion is 1.986:1:2.114. The fertilizing method comprises the steps as follows: firstly, all the phosphate fertilizer, 45% of the nitrogen fertilizer and 45% of the potash fertilizer are taken as base fertilizer to be applied in cultivating soil, then 25% of the nitrogen fertilizer and 25% of the potash fertilizer are applied as the first additional fertilizer at the tillering stage, and the remaining 30% of the nitrogen fertilizer and the remaining 30% of the potash fertilizer are distributed averagely and applied after reaping of each time. According to the invention, suitable nitrogen fertilizer, phosphate fertilizer and potash fertilizer are selected and the nitrogen fertilizer, the phosphate fertilizer and the potash fertilizer are used in proper proportions, so that the nutrition requirement of orchard grass can be well met, and meanwhile, the fertilizing manner is combined to fully improve nutrition absorption of orchard grass in the early and later growing periods; therefore, the quality of orchard grass can be improved effectively, the yield can reach59450.33 kg/hm<2>, the energy consumption is reduced, environment pollution is avoided, the soil fertility is improved, and the economic benefits in production of orchard grass can be increased greatly.

Description

technical field [0001] The invention relates to a pasture fertilization method, in particular to a high-yield and high-quality fertilization method for duckweed. Background technique [0002] Dactylis, also known as chicken foot grass and orchard grass, is native to Europe, North Africa and Asia in the temperate zone. It is one of the world-renowned temperate grasses. It has been planted in North America for more than 200 years. It is currently one of the large-scale cultivated grasses in the United States. First, it is also one of the excellent mixed grass species for understory grassland and high-efficiency artificial grassland. [0003] In recent years, duckweed has been widely cultivated and applied in Sichuan, Chongqing, Shanxi, Gansu, Heilongjiang and other places in my country, and has achieved certain economic, ecological and social benefits. However, in the process of planting Dactylis chinensis, there was no in-depth research on Dactylis sagerum, and the balanced ...
