Fertilizing method for orchard grass

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 ...

Problems solved by technology

However, in the process of planting Dactylis chinensis, there was no in-depth research on Dactylis sagerum, and the balanced application of nitrogen, phosphorus and potassium was not made according to the local soil fertility. As a result, the production performance and grass quality of Dactylis sativa were not high, and environmental pollution was caused. The economic benefit of cultivation needs to be improved
