A Simplified Fertilization Method for Wheat and Peanut Anniversary in Hilly Land

Abstract

The invention relates to a simplified fertilization method for wheat and peanuts in hilly land, which comprises spreading nitrogen, phosphorus and potassium fertilizers evenly on the ground 1-2 days before wheat sowing, and applying trace elements at the same time. 20%-30% of the total nutrients, the amount of phosphorus fertilizer application accounts for 60%-70% of the total phosphorus fertilizer nutrients required per mu, and the amount of potassium fertilizer application accounts for 40%-50% of the total potassium fertilizer nutrients required per mu; The second fertilization is carried out at the jointing stage of wheat, and the remaining fertilizer of nitrogen, phosphorus and potassium fertilizers required per mu is applied. The annual simplified fertilization method of the present invention takes into account the supply of nutrients in the later stage of wheat, and simultaneously provides basic fertilizers for peanuts after stubble, This fully considers the nitrogen fixation effect of peanut root nodules, reduces fertilizer input, and avoids the negative impact of excessive application of fertilizer nutrients, especially nitrogen nutrients, on groundwater; reduces fertilizer input by 1-2 times compared with traditional fertilization methods, saving Labor input costs.

Description

technical field [0001] The invention relates to a method for fertilizing winter wheat and summer peanuts, in particular to a method for simplifying the frequency of fertilization by twice-cropping winter wheat and summer peanuts in northern hilly areas, and belongs to the technical field of agricultural fertilization. Background technique [0002] Winter wheat is the main food crop in my country, and peanut is also an important oil crop. Both are the main crops grown in northern my country. Affected by annual caloric resource constraints and ecological regions, as well as traditional planting habits and government guidance, and to effectively alleviate the conflict between grain and oil, intercropping of winter wheat and summer peanuts is an important planting in some northern areas, especially in hilly areas. Way. Affected by the soil-forming parent material, the hilly land is generally sandy soil or loamy soil. The soil of this texture is very suitable for the growth, pod...

Problems solved by technology

The traditional fertilization operation has the following problems: first, the variety of fertilization is single or complicated, and fertilization is relatively random in wheat season and peanut season, and there is no corresponding fertilizer nutrient input according to the needs of crops for various nutrients; second, the time of fertilization Although it is relatively reasonable, the number of times is too high, which is in contradiction with the current situation of decreasing rural labor force. Moreover, some farmers miss the application of topdressing fertilizer because they cannot return to work outside the home, resulting in insufficient supply of nutrient inputs. The existing fertilizer types are basically The quick-acting type lacks slow-release fertilizers or long-acting fertilizers suitable for wheat and peanuts, and cannot meet the nutrient requirements of crops throughout the growth period through one-time use; the third is that when peanuts are topdressed in the later stage, they are already at the beginning of pod formation , Topdressing is not easy to operate, if the method of spreading fertilizer is used, it will lead to serious fertilizer loss and low nutrient utilization rate, and if the method of furrowing is used, it will cause damage to peanut roots and pods, thus affecting the yield

[0004] Chinese patent document CN1561662A (application number: 200410023889.1) discloses the heavy-duty fertilization method before double cropping of wheat and peanuts. This method mainly proposes the ratio of fertilization amount of peanuts after cropping based on the annual nutrient distribution ratio of wheat and peanut intercropping under different fertilization levels. It only accounts for 10%-35%, and such a nutrient amount can be satisfied by the second fertilization of the last stubble wheat, so it will lead to too many times of fertilization, which is inconsistent with the current development trend of light and simplified production. Fertilization methods do not limit the types of fertilizer nutrients. Common quick-acting fertilizers cannot meet the nutrient needs of crops in the longer growth period, and the amount of nitrogen topdressing in the later stages of the wheat season is relatively small, which cannot meet the nutrient needs of wheat in the later stages of growth. Wheat yield Can not guarantee
