Problems solved by technology

[0003] In many areas of our country, the soil shows both potassium deficiency and boron deficiency and other nutrient deficiencies; in addition, in recent years, the application of nitrogen and phosphorus fertilizers has increased year by year, and the relative decrease of organic fertilizers has caused the lack of various nutrients such as potassium and boron deficiency. The phenomenon is becoming more and more serious and has become a limiting factor affecting the improvement of crop yields

Embodiment 1

[0014] The cold-resistant foliage fertilizer includes the following components by weight: 25 parts of boric acid, 30 parts of potassium carbonate, 10 parts of ε-polylysine, 10 parts of humic acid, 20 parts of methylene succinic acid, 12 parts of trace elements, 0.3 part of diethylaminoethanol caproate, 60 parts of water, 0.5 part of disodium edetate.

[0015] The trace elements contain by weight: 5 parts of zinc, 0.4 part of copper, 0.5 part of iron, 0.4 part of manganese, and 0.3 part of molybdenum. The ingredients in the cold-resistant foliar fertilizer are mixed according to the weight ratio, the stirring speed is 200-300r / min, and the reaction is carried out at 75-80°C for 30min. Using the cold-resistant foliar fertilizer for cucumber planting can increase yield by 21.2% and reduce insect damage rate by 19.6%.

The trace elements contain by weight: 10 parts of zinc, 1 part of copper, 1 part of iron, 1 part of manganese, and 0.5 part of molybdenum. The ingredients in the cold-resistant foliar fertilizer are mixed according to the weight ratio, the stirring speed is 200-300r / min, and the reaction is carried out at 75-80°C for 30min.

[0018] Using the cold-resistant foliar fertilizer for corn planting can increase yield by 18.5% and reduce insect damage rate by 14.8%.

Embodiment 3

[0020] The cold-resistant foliage fertilizer includes the following components by weight: 20 parts of boric acid, 25 parts of potassium carbonate, 5 parts of ε-polylysine, 5 parts of humic acid, 10 parts of methylene succinic acid, 2 parts of trace elements, 0.1 part of diethylaminoethanol caproate, 50 parts of water, 0.1 part of disodium edetate.

[0021] The trace elements contain by weight: 1 part of zinc, 0.2 part of copper, 0.2 part of iron, 0.2 part of manganese, and 0.1 part of molybdenum.

[0022] The ingredients in the cold-resistant foliar fertilizer are mixed according to the weight ratio, the stirring speed is 200-300r / min, and the reaction is carried out at 75-80°C for 30min.

[0023] Using the cold-resistant foliage fertilizer for loofah planting can increase yield by 15.8% and reduce insect damage rate by 18.4%. .

Abstract

The invention belongs to the field of pesticides, and particularly relates to a cold-resistant foliar fertilizer which comprises boric acid, potassium carbonate, epsilon-polylysine, humic acid, itaconic acid, trace elements, diethyl aminoethyl hexanoate, water and a chelating agent. The cold-resistant foliar fertilizer has the advantages of disease prevention and bacteriostasis, stress resistanceand phytotoxicity removal, is rich in boron and potassium elements, meets the requirements of crop growth and development, and enhances the economic benefits.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, and specifically discloses a cold-resistant foliage fertilizer. Background technique [0002] There are two main ways for plants to absorb nutrients, namely roots and leaves. Crops mainly absorb nutrients in the soil or nutrient solution through roots to supply plant growth and development. In addition to roots, crops can also absorb nutrients through stems and leaves (especially leaves). This phenomenon of non-root absorption of nutrients during crop growth is crop growth. The method of fertilizing the surface of nutrient absorbers other than the root system of crops is generally foliar fertilization. [0003] In many areas of our country, the soil shows both potassium deficiency and boron deficiency and other nutrient deficiencies; in addition, in recent years, the application of nitrogen and phosphorus fertilizers has increased year by year, and the relative decrease of organ...
