Abstract

The invention provides a foliar fertilizer specially used for Chinese gooseberries, which has the functions of cold resistance and consists of the following raw materials according to weight percentage: 0.1 to 8 percent of DMSO, 0.05 to 5 percent of trimethylene glycol, 0.05 to 5 percent of salicylic acid, 0.05 to 2 percent of compound ammonium nitrate, 1 to 15 percent of humic acid, 0.5 to 10 percent of chitosan, 1 to 10 percent of citric acid, 2 to 15 percent of urea, 1 to 10 percent of borax, 1 to 20 percent of zinc sulfate, 0.5 to 10 percent of ferrous sulfate, 0.05 to 5 percent of ammonium molybdate, 1 to 15 percent of manganese sulfate, 0.1 to 2 percent of SDBS and 35 to 80 percent of water. The foliar fertilizer has obvious effects of enhancing the cold resistance of the Chinese gooseberries, coordinating the nutrient balance in plant corpus, promoting the growth, increasing the output and improving the quality.

Description

A kind of foliage fertilizer special for kiwi berry with anti-cold effect

Technical field

The present invention relates to foliage fertilizer special for kiwi berry, be meant a kind of foliage fertilizer special for kiwi berry especially with anti-cold effect.

Background technology

Kiwifruit is a kind of nutritious, fruit that economic worth is high, have the laudatory title of " king of fruit ".China is the original area of origin of world's Kiwifruit, and since the eighties in last century, the commercial cultivation and production of China's Kiwifruit has obtained fast development.In autumn and winter and time in early spring, the growth of Kiwifruit not only is subjected to the harm of low-temperature cold weather, but also the degradation reason causes malnutrition under, the root system of plant receptivity under-supply because of soil nutrient, is seriously restricting the raising of Kiwifruit yield level.In the cultivation management of Kiwifruit, rationally use foliage fertilizer and be and realize its high yield, high-quality, major measure efficiently.Yet existing kiwi fruit leaf leaven lacks targetedly, the rational fertilizer application formula of nutrition-allocated proportion, and it is single often to fill a prescription, and is difficult to satisfy Kiwifruit in the demand of different growth and development stages to various nutritive elements, not obvious to the Kiwi growth promoter action.And, also exist abuse tethelin, blindness to pursue the big fruit of fruit in the production formula of existing kiwi fruit leaf leaven and heavily wait problem, caused adverse consequencess such as quality of Chinese gooseberries decline, value fall sharply.

Summary of the invention

The object of the present invention is to provide a kind of foliage fertilizer special for kiwi berry with anti-cold effect, to overcome the deficiency that prior art exists, provide with low cost, reasonable, easy to use, the stable performance of prescription, a kind of foliage fertilizer special for kiwi berry that biological effectiveness is high with anti-cold effect.To strengthening the Kiwifruit cold tolerance, coordinate nutritive equilibrium in the plant materials, promote growth, increase output, improving the quality aspect and have significant effect.

The present invention is made up of the raw material of following each weight percentages of components: dimethyl sulfoxide (DMSO) 0.1%～8%, propylene glycol 0.05%～5%, Whitfield's ointment 0.05%～5%, multiple ammonium nitrate 0.05%～2%, humic acid 1%～15%, chitosan 0.5%～10%, citric acid 1%～10%, urea 2%～15%, borax 1%～10%, zinc sulfate 1%～20%, ferrous sulfate 0.5～10%, ammonium molybdate 0.05%～5%, manganous sulfate 1%～15%, Sodium dodecylbenzene sulfonate 0.1%～2%, water 35%～80%.

The present invention realizes by the following technical solutions: with weight percentages of components is that 1%～15% humic acid, 0.5%～10% chitosan, 1%～10% citric acid, 2%～15% urea, 1%～10% borax, 1%～20% zinc sulfate, 0.5%～10% ferrous sulfate, 0.05%～5% ammonium molybdate, 1%～15% manganous sulfate are put into reactor, with weight percentages of components is 35%～80% water dissolution, mixes reaction 0.5～5 hour under 60～110 ℃.After reaction process to be mixed is finished, with 100～120 mesh sieve filtering solutions.Then, adding weight percentages of components in the filtering solution is 0.1%～8% dimethyl sulfoxide (DMSO), 0.05%～5% propylene glycol, 0.05%～5% Whitfield's ointment, 0.05%～2% multiple ammonium nitrate.The last weight percentages of components that adds again is 0.1%～2% Sodium dodecylbenzene sulfonate, and stirs and can obtain the finished product.

The present invention is further illustrated below in conjunction with embodiment.

Embodiment 1:

With weight percentages of components is that 5% humic acid, 2% chitosan, 8% citric acid, 5% urea, 5% borax, 10% zinc sulfate, 10% ferrous sulfate, 2% ammonium molybdate, 5% manganous sulfate are put into reactor, with weight percentages of components is 40% water dissolution, mixes reaction 3 hours under 100 ℃.After reaction process to be mixed is finished with 100 mesh sieve filtering solutions.Then, adding weight percentages of components in the filtering solution is 3% dimethyl sulfoxide (DMSO), 1.5% propylene glycol, 2% Whitfield's ointment, 0.5% multiple ammonium nitrate.The last weight percentages of components that adds again is 1% Sodium dodecylbenzene sulfonate, and stirs and can obtain the finished product.

Embodiment 2:

Schedule of operation is identical with embodiment 1 during preparation.Just in the scope of schedule of operation defined of the present invention, raw material types, quantity and reaction times, temperature of reaction are changed, still be prepared into a kind of foliage fertilizer special for kiwi berry of the present invention equally with anti-cold effect.

Claims

1. A special foliar fertilizer for kiwi fruit with cold resistance, which is composed of the following raw materials in weight percentage: dimethyl sulfoxide 0.1% to 8%, propylene glycol 0.05% to 5%, salicylic acid 0.05%～5%, double ammonium nitrate 0.05%～2%, humic acid 1%～15%, chitosan 0.5%～10%, citric acid 1%～10%, urea 2%～15%, borax 1 %～10%, zinc sulfate 1%～20%, ferrous sulfate 0.5%～10%, ammonium molybdate 0.05%～5%, manganese sulfate 1%～15%, sodium dodecylbenzenesulfonate 0.1%～ 2%, water 35% ~ 80%.
