Problems solved by technology

However, there is no special fertilizer for potato-soybean intercropping in the prior art, and there are defects that farmers rely on experience in fertilization, only use heavy nitrogen and phosphorus fertilizers, and ignore the application of potassium fertilizers and medium and trace element fertilizers, resulting in low fertilizer utilization efficiency and blindness in fertilization

Embodiment 1

[0020] In 2015, a comparative field test was conducted in Dayangying Village, Guocheng Township, Huining County, using a strip width of 150 cm. Among them, 100 cm of film-covered potatoes were planted in 2 rows, the height of the ridge was 30 cm, and the surface of the ridge was curved. Potato planting density 47625 holes / hm 2 , the row spacing is 45cm, the hole spacing is 28cm, and the other 50cm is planted with 2 rows of soybeans, and the density is 120,000 plants / hm 2 , the row spacing is 40cm, and the fertilizer, water and field management are the same as the local production measures. Potato (variety Feureta) and soybean (variety Jidou 12) were selected as test materials, compared with traditional fertilization, the yield of soybean increased by 21.09%, and the yield of potato increased by 18.54%.

[0021] The nutrient status of the soil at 0-20cm before fertilization is as shown in Table 1, and the nutrient status is measured by the method shown in "Soil Agrochemical An...

Embodiment 2

[0031] In 2016, the field comparative experiment of Huangyang Farm Experimental Station in Liangzhou District, Wuwei City, the potato planting density was 52500 holes / hm 2 , the row spacing is 45cm, the hole spacing is 28cm, and the other 50cm is planted with 2 rows of soybeans, and the density is 120,000 plants / hm 2 , the row spacing is 40cm, the potato variety is Feiwu Ruita, and the soybean variety is Jidou 17. Compared with the traditional fertilization, the application of special fertilizer increases the soybean yield by 20.3%, and the potato yield increases by 14.71%.

Abstract

The invention discloses a special potato-soybean relay strip intercropping fertilizer and a production method thereof, and belongs to the technical field of agriculture, wherein the special potato-soybean relay strip intercropping fertilizer comprises urea, monoammonium phosphate, potassium sulfate, zinc sulfate, ammonium molybdate, ferrous sulfate, borax, a water retaining agent, a nitrogen fertilizer synergist, and activated attapulgite. According to the present invention, the special potato-soybean relay strip intercropping fertilizer is prepared according to the potato-soybean fertilizer requirement law, and has characteristics of strong targeting property and reasonable nitrogen-phosphorus-potassium ratio, wherein the requirements on nitrogen at different growth and development stages can be met with the added nitrogen fertilizer synergist, and the trace elements are added according to a certain ratio so as to improve the fertilizer utilization efficiency and achieve the balanced fertilizer application; and the defects of poor fertilizer efficiency persistence and the like in the prior art can be overcome, the one-time application of the fertilizer during the planting can be achieved, the application is convenient, the fertilizer efficiency persistence is good, and the yield increasing and the fertilizer efficiency increasing can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a special fertilizer for potato-soybean intercropping and a preparation method thereof. Background technique [0002] Intercropping can effectively increase crop yield, enhance soil and water conservation capacity, improve soil fertility, and inhibit the occurrence of pests and weeds. It has become a planting model with high yield and efficient nutrient utilization in modern agriculture. However, how to rationally apply chemical fertilizers is a concern of today's cultivation experts while efficiently utilizing limited cultivated land resources, continuously increasing the yield of cultivated land, and protecting the stable development of food. [0003] In recent years, the potato-soybean intercropping planting method has been popularized in a large area in Northwest China. Potato-bean intercropping can not only increase the yield of potatoes, but also increase the yield of soy...
