Water-saving fertilizing method for wheat

Abstract

The invention discloses a water-saving fertilizing method for wheat. The water-saving fertilizing method comprises the steps that 1 seeding is conducted before winter, and land is arranged into strip-shaped farmland before the seeding is conducted; seeding is conducted, a fertilizing groove is arranged in the middle position of two adjacent rows, the fertilizing groove is divided into two types, namely a deep groove and a shallow groove, the deep groove and the shallow groove are arranged at an interval, and then fertilizing is conducted; after the fertilizing is conducted, fertilizer is covered with straw or straw fermentation materials; 2 when the wheat is in a period from a jointing stage to booting stage, one-time irrigating is conducted, by adopting the mode that irrigating is limited in quantity and conducted on separated farmland, the two adjacent farmland is irrigated with 35-45 mm water and 15-25 mm of water respectively; 3 when the wheat is in a grain filling stage, by adopting the mode that the irrigating is limited in quantity and conducted on separated farmland, the water irrigating amount of the two adjacent farmland is exchanged with irrigating last time. According to the water-saving fertilizing method for the wheat, the fertilizing method is scientific and reasonable, the use ratio of the fertilizer is effectively improved, the labor intensity of fertilizing is relieved, the water used for irrigating is effectively used, the water resources are saved, the important economic significance and social significance are achieved, and the method is worth using and popularizing.

Description

technical field [0001] The invention relates to a water-saving fertilization method for wheat. Background technique [0002] Our country has a lot of people and little land, so the task of achieving self-sufficiency and satisfying food and drink is heavy. One of the main reasons is that the fertilization technology is backward, and farmers apply fertilizer blindly, resulting in low crop efficiency and poor quality, let alone the inability to fully utilize and tap land resources. It has affected the rapid improvement of our people's living standards and the rapid development of national strength. [0003] Wheat is an important food crop and one of the most important rations in my country. The development of the wheat industry is directly related to national food security and social stability. At present, in the process of wheat planting and fertilization by farmers in our country, there is a common phenomenon: "Fertilizers follow one, not according to their own soil strength...
