Problems solved by technology

[0008] The method currently used is very backward, because lime nitrogen is slightly soluble in water, the preparation time of lime nitrogen solution is long, the particles of lime nitrogen are large, the suspension rate in water is low, the wet spreading performance on fruit branches is poor, the dosage is large, and it is not resistant to rainwater erosion. Uneven coating is easy to cause fertilizer damage, low efficiency and other shortcomings

Embodiment 1

[0024] A practical example is used below to illustrate the configuration of lime nitrogen oil suspension. Take 20 kg of lime nitrogen, 5 kg of castor oil BY-201 as a wetting and dispersing agent, 2 kg of organic bentonite as a structure regulator, 0.5 kg of 2,6-di-tert-butyl-4-methylphenol as a stabilizer, and 72.5 kg of vegetable oil methyl oleate kg, ground in a sand mill and homogenized to become a lime nitrogen oil suspension, the resulting product meets the following requirements:

[0025]

[0026] The lime nitrogen oil suspension of this formula is diluted 20 times when used, and it is used for spraying or brushing on the branches of fruit trees.

[0027] Adopt the obtained lime nitrogen oil suspension of embodiment 1, to the influence of grape germination and fruit setting, as follows:

[0028] Effects of 20 times lime nitrogen oil suspension on grape germination in protected areas (2011)

[0029] (Test location: Jinan Changqing Garden Expo Garden Nursery Greenhous...

Embodiment 2

[0036] Take 5.0 kg of lime nitrogen, 5.0 kg of wetting and dispersing agent castor oil polyoxyethylene ether BY-120, 2.0 kg of structure regulator carrageenan, 1.0 kg of stabilizer 2,6-di-tert-butyl-4-methylphenol, vegetable oil 87.0 kilograms of acid methyl esters become lime nitrogen oil suspension after grinding and homogenizing.

Embodiment 3

[0038] Take 9.0 kg of lime nitrogen, 2.5 kg of wetting and dispersing agent castor oil polyoxyethylene ether BY-140, 2.0 kg of carboxymethyl cellulose as a structural regulator, 1.5 kg of epoxy linseed oil as a stabilizer, and 84.8 kg of vegetable oil methyl oleate, grind , After homogenization, it becomes lime nitrogen oil suspension.

Abstract

The invention discloses a calcium cyanamide oil suspension, the formula of which comprises the following substances by mass percent: 5-30% of calcium cyanamide, 1-5% of wetting dispersant, 1-2.5% of structure regulator, 0.5-2% of stabilizer and the balance of vegetable oil or mineral oil. The calcium cyanamide oil suspension can greatly improve the wetting and spreading performance on fruit branches and permeating performance on branches of calcium cyanamide, improves rainfall erosion resistance, overcomes the shortcomings of fertilizer damage caused by nonuniform coating, low use work efficiency and the like of the original method, prolongs the retention time of the effective ingredients on the branches, reduces the consumption of calcium cyanamide, reduces dust pollution, greatly improves use effect of calcium cyanamide and is convenient for transportation and application. The calcium cyanamide oil suspension can be applied to a dormancy breaking agent of grape, apple, pear, peach cherry and other fruit trees.

Description

technical field [0001] The invention belongs to the field of agricultural chemicals, in particular to a lime nitrogen oil suspension, which is used as a sleep breaker for horticultural plants such as grapes. Background technique [0002] Lime nitrogen chemical name is calcium cyanamide, molecular formula CaCN 2 , molecular weight 80.09, prepared by treating calcium carbide powder with nitrogen at high temperature. In industry, it is mainly used to produce dicyandiamide, yellow blood salt, guanidine and thiourea; in agriculture, in addition to being used as a nitrogen fertilizer, it also has the effect of improving soil acidity, and is an important organic chemical raw material. [0003] The growth inhibitory substance in grape dormancy is abscisic acid (ABA), which can be degraded at low temperature below 7.2°C. When the grapes reach the required low temperature, the problem of winter bud dormancy can be solved. Treating fruiting branches with lime nitrogen can promote the...
