Problems solved by technology

[0004] Spraying micro-fertilizers by drones has high efficiency and fast speed, and is suitable for large-scale agricultural applications. Speed, the micro-fertilizers that fall into the leaves are easy to fall, resulting in waste of fertilizers, and it is not easy to spray to the middle and lower parts of the plants. The spray area is smaller than that of ground spraying. Therefore, it is necessary to study a micro-fertilizer suitable for drone spraying. Method or formula to save fertilizer and improve fertilizer efficiency

Embodiment 1

[0015] The test was carried out in Songzhuang Village, Changyuan City, Xinxiang City, Henan Province (114°85, E, 35°22, N) from 2019 to 2020. The soil type of the test site is fluvo-aquic soil, the soil texture is loam, and the soil layer is 0-20cm The organic matter content is 13.16g / kg, the total nitrogen is 1.02g / kg, the available phosphorus is 15.41mg / kg, the available potassium is 110.51mg / kg, the available iron is 10.05mg / kg, the available zinc is 1.03mg / kg, and the pH value is 8.23.

[0016] Experimental design: The experiment was designed by two-factor random block method, and the wheat variety Zhengmai 0943 was used as the experimental material. Spray iron, zinc, selenium mixed fertilizer on foliage as a secondary area, prepare micro-fertilizers of different formulas as follows:

[0017] (1) Spray water CK.

[0018] (2) Micro fertilizer T1: 5% FeSO 4 ·7H 2 O, 5% ZnSO 4 ·7H 2 O, 0.2% Na 2 SeO 3 , 2% mannitol, 1% starch acetate, and the balance is water.

Abstract

The invention discloses a micro-fertilizer for foliage spraying by an unmanned aerial vehicle. A micro-fertilizer with a specific concentration, the micro-fertilizer uses octyl glucoside and hexyl laurate as absorption-promoting agents, and the micro-fertilizer uses mannitol and acetate starch as absorption-promoting agents. The foliage micro-fertilizer prepared by the present invention uses octyl glucoside and hexyl laurate as auxiliary agents to promote the absorption of Fe, Zn, and Se elements, and has a significant synergistic effect; the micro-fertilizer uses mannitol and acetic acid As an additive to promote the absorption of Fe, Zn, and Se elements, ester starch also has a significant synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of foliar fertilizers, and in particular relates to a micro-fertilizer for foliar spraying by an unmanned aerial vehicle. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, the issue of "hidden hunger" has attracted more and more attention from agricultural organizations and scientists in various countries. It not only has a direct negative impact on people's healthy living standards, but also has Human social development has also brought about potentially huge economic losses. When human beings maintain their normal life activities, in addition to supplementing the three major nutrients of protein, fat and sugar, they also need a variety of essential nutrients such as mineral elements and vitamins. In 2005, the World Health Organization classified this long-term The phenomenon that insufficient intake of essential nutrients ...
