Abstract

The invention discloses a yearly simple fertilizing method for green Chinese onion and wheat grown in shift, which takes the nutrient demands and distribution in different periods in a year of double-harvest crops into consideration, mixes a green Chinese onion long-acting sustained-release fertilizer and a wheat long-acting sustained-release fertilizer for application, is low in cost and convenient for mixing and allows the mixed fertilizer to be used instantly. In the invention, fertilizer is applied only for 4 times, labor force is saved, the wheat yield is increased, and the utilization rate of nitrogen fertilizer is improved by 5 to 7 percent.

Description

Technical field: [0001] The invention relates to an annual simplified fertilization method for green onion and wheat rotation, and belongs to the technical field of long-acting slow-release fertilizer and its application. Background technique: [0002] Shandong has a long history of open field scallion cultivation. Among them, Zhangqiu scallion is a well-known brand in the country. It is named after it was produced in Zhangqiu City. The plant is tall, white and long, with delicate and juicy texture, rich in nutrients, suitable for long-term storage. "", "special", and "excellent" are both known as the "king of green onions" and one of the famous specialty products of Shandong Province. [0003] At present, Zhangqiu's green onion planting area and output and brand effect are of great significance in the province and even the whole country. Its annual rotation planting system with wheat is the main local planting mode. Generally, green onions are transplanted and planted in late June...
