Description

A special foliar fertilizer for kiwifruit with cold resistance

technical field

The invention relates to a special foliage fertilizer for kiwifruit, in particular to a special foliage fertilizer for kiwifruit with cold resistance.

Background technique

Kiwi is a fruit with rich nutrition and high economic value, known as the "King of Fruits". my country is the original origin of kiwifruit in the world. Since the 1980s, the commercial cultivation and production of kiwifruit in my country has developed rapidly. In autumn, winter and early spring, the growth of kiwifruit is not only harmed by low temperature and cold weather, but also malnutrition due to insufficient supply of soil nutrients and decreased absorption capacity of plant roots, which seriously restricts the increase in kiwifruit production. In the cultivation and management of kiwifruit, rational application of foliar fertilizer is the main measure to achieve high yield, high quality and high efficiency. However, existing kiwifruit foliar fertilizers lack targeted fertilization formulas with reasonable nutrient ratios, and often have a single formula, which is difficult to meet the needs of kiwifruit for various nutritional elements at different growth and development stages, and has no obvious growth-promoting effect on kiwifruit. Moreover, the existing kiwifruit foliar fertilizer production formula still has problems such as abuse of growth hormones and blind pursuit of large fruit weight, which has caused adverse consequences such as decline in quality and sharp drop in value of kiwifruit.

Contents of the invention

The purpose of the present invention is to provide a special foliar fertilizer for kiwifruit with cold resistance, to overcome the deficiencies in the prior art, to provide a kind of fertilizer with low cost, reasonable formula, convenient use, stable performance and high biological effectiveness. Special foliar fertilizer for kiwi fruit with cold resistance. It has significant effects on enhancing the cold resistance of kiwifruit, coordinating the nutritional balance in plants, promoting growth, increasing yield, and improving quality.

The present invention is composed of the raw materials of the following components by weight percentage: 0.1% to 8% of dimethyl sulfoxide, 0.05% to 5% of propylene glycol, 0.05% to 5% of salicylic acid, and 0.05% to 2% of double ammonium nitrate , humic acid 1% to 15%, chitosan 0.5% to 10%, citric acid 1% to 10%, urea 2% to 15%, borax 1% to 10%, zinc sulfate 1% to 20%, sulfuric acid 0.5% to 10% of ferrous iron, 0.05% to 5% of ammonium molybdate, 1% to 15% of manganese sulfate, 0.1% to 2% of sodium dodecylbenzenesulfonate, and 35% to 80% of water.

The present invention is realized through the following technical scheme: the components by weight percentage are 1% to 15% of humic acid, 0.5% to 10% of chitosan, 1% to 10% of citric acid, 2% to 15% % urea, 1%~10% borax, 1%~20% zinc sulfate, 0.5%~10% ferrous sulfate, 0.05%~5% ammonium molybdate, 1%~15% manganese sulfate Put it into a reaction kettle, dissolve it in water with a component weight percentage of 35% to 80%, stir and mix and react at 60 to 110°C for 0.5 to 5 hours. After the mixing reaction process is completed, filter the solution with a 100-120 mesh sieve. Then, add 0.1% to 8% dimethyl sulfoxide, 0.05% to 5% propylene glycol, 0.05% to 5% salicylic acid, 0.05% to 2% double nitrification to the filtered solution Ammonium. Finally, add sodium dodecylbenzenesulfonate with a component weight percentage of 0.1% to 2%, and stir evenly to obtain the final product.

The present invention will be further described below in conjunction with embodiment.

Example 1:

The component weight percent is 5% humic acid, 2% chitosan, 8% citric acid, 5% urea, 5% borax, 10% zinc sulfate, 10% ferrous sulfate, 2% % ammonium molybdate and 5% manganese sulfate are put into the reactor, dissolved in water with a component weight percentage of 40%, stirred and mixed for 3 hours at 100°C. After the mixing reaction process is completed, filter the solution with a 100-mesh sieve. Then, the weight percentage of 3% dimethyl sulfoxide, 1.5% propylene glycol, 2% salicylic acid and 0.5% double ammonium nitrate are added to the filtered solution. Finally, add sodium dodecylbenzenesulfonate with a component weight percentage of 1%, and stir evenly to obtain the final product.

Example 2:

The operating procedure was the same as in Example 1 during preparation. Just change the raw material type, quantity, reaction time, and reaction temperature within the scope specified by the operating procedure of the present invention, and still prepare a kind of kiwifruit special-purpose foliage fertilizer with cold resistance effect of the present invention in the same way.
