Embodiment 1

[0028] The experiment is located in the Shenyang Ecological Station of the Chinese Academy of Sciences, which is located in the center of the Liaohe Plain, about 35km away from Shenyang City. The planting soil is meadow brown soil, and the excavation depth is 20cm. Its basic physical and chemical properties are shown in Table 1.

[0029] Table 1 Physical and chemical properties of the tested soil

[0030]

[0031] The millet variety in this experiment was Jingu No. 3, which was planted in pots. The experiment uses ceramic pots, 30cm high and 30cm in diameter. The area of ​​each pot is 0.071m 2 , about 0.00011 mu. After the soil for testing was air-dried, it passed through a 2mm sieve, and then added base fertilizers, namely nitrogen, phosphorus and potassium fertilizers. The nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer are urea, superphosphate and potassium chloride respectively. The dosages are 3.2g / pot, 6.4g / pot and 1.6g / pot respectively. Afte...

Embodiment 2

[0043] The millet variety in this experiment was Jingu No. 3, which was planted in pots. Experimental method is with embodiment 1.

[0044] Experimental Design Control 3 pots (CK1, CK2, CK3), the experimental group was sprayed with 6 pots of selenium-enriched fertilizer (7 # -12 # ), a total of 6 pots. The area of ​​each pot is 0.071m 2 , about 0.00011 mu, CK1, CK2, CK3, spray the same amount of dilution water instead of selenium fertilizer.

[0045] The composition of the foliar spray fertilizer in this experiment is: selenium, sulfur, manganese, zinc, magnesium, alkyl polyglycosides, chitosan, chitosan quaternary ammonium salt, calcium and molybdenum.

[0046] The preparation of selenium-rich fertilizer A is calculated in parts by weight: 1.5 (selenium): 20 (sulfur): 9 (manganese): 9 (zinc): 15 (magnesium): 24 (calcium): 2 (molybdenum): 15 ( Chitosan), after weighing respectively, add water and settle to 1000ml, be prepared into foliar spray fertilizer A1. Weigh 2.0 (a...

Abstract

The invention relates to an agricultural product production technology in the field of agricultural fertilizers, in particular to foliar spray fertilizer for millets and a preparation method and application of the foliar spray fertilizer. The foliage spray fertilizer is prepared from the following components in parts by weight: 0.8-1.5 parts of selenium, 10-40 parts of sulfur, 5-15 parts of manganese, 5-15 parts of zinc, 10-40 parts of magnesium, 1-4 parts of alkyl polyglycoside, 10-30 parts of chitosan, 2-6 parts of chitosan quaternary ammonium salt, 15-35 parts of calcium and 1-5 parts of molybdenum.In order to solve the problem that selenium absorption and utilization of plants are influenced, the relation between sulfur and selenium is taken as an entry point, the proper proportion range of sulfur and selenium, cation type selection and dosage matched with sulfur, surfactant dosage adjustment after sulfur and other elements are added, leaf surface protection measures and the like are emphatically studied, and a series of experiments are carried out. The invention provides the preparation method and application of the selenium-enriched high-yield spray fertilizer for millet.

Description

technical field [0001] The invention relates to the production technology of agricultural products in the field of agricultural fertilizers, in particular to a fertilization method for spraying millet leaves and its preparation and application. Background technique [0002] Academician Zhao Qiguo recently pointed out: Functional agriculture refers to the agricultural production process that quantitatively increases selenium, zinc and other minerals or other functional substances that are beneficial to human health in agricultural products through biological nutrition enhancement technology. It is the third agricultural production process after high-yield agriculture and green agriculture. This stage of agricultural development is one of the emerging agricultural directions that are most likely to make breakthroughs. [0003] An important role of functional agriculture is to eliminate "hidden hunger". According to statistics, the proportion of the world's population suffering...
