Embodiment 1

[0033] This example provides a composite water-retaining agent for potatoes, which can be used as a special water-retaining agent during the planting and growth of potatoes. The water-retaining agent contains the following raw materials mixed in the weight ratio, and each raw material is:

[0034] Potassium humate 2-12

[0035] Water retaining agent 14-36

[0036] Urea 16-24

[0037] Calcium hydrogen phosphate 16-24

[0038] Potassium sulfate fertilizer 8-12

[0039] Lanthanum nitrate 1

[0040] Yttrium nitrate 1

[0041] Crosslinkers 5-7.

[0042] In the above compound water retaining agent formula, the various raw materials cooperate with each other to form a water retaining agent that can play a good role in water retention when used in the planting and growth of potatoes. First, the functions of each raw material in the formula will be explained one by one. :

[0043] Among them, the nitrogen in the formula of the above-mentioned compound water-retaining agent can s...

Embodiment 2

[0060] This example provides a method for preparing a composite water-retaining agent for potatoes, which is mainly used to produce the composite water-retaining agent given in the examples of the present invention. The method is specifically carried out according to the following steps (see figure 1 ):

[0061] Get each raw material according to the formula given in the above-mentioned examples by weight: Potassium humate 2-12, water retaining agent 14-36, urea 16-24, calcium hydrogen phosphate 16-24, potassium sulfate fertilizer 8-12, lanthanum nitrate 1 , yttrium nitrate 1, crosslinking agent 5-7;

[0062] The urea is commercially available urea, and the calcium hydrogen phosphate is commercially available phosphate fertilizer. The urea and phosphate fertilizer are all crushed into powder, and are sieved for later use;

[0063] Potassium humate, water retaining agent, and potassium sulfate fertilizer in the raw materials are also crushed into powder and sieved, mixed with ...

Embodiment 3

[0069] This embodiment provides a composite water-retaining agent for potatoes. In the composite water-retaining agent, the raw materials are calculated by weight ratio: Potassium humate 12, water-retaining agent 28, urea 16, calcium hydrogen phosphate 16, potassium sulfate fertilizer 8, Lanthanum nitrate 1, yttrium nitrate 1, crosslinking agent glycerin 6; in practice, the consumption given in the table below can get each raw material:

Abstract

The embodiment of the invention provides a compound water retention agent used in potatoes and a preparation method thereof. The water retention agent is formed by blending the following raw materials according to the weight ratio: 2-12 of humic acid kalium, 14-36 of water retention agent, 16-24 of urea, 16-24 of calcium hydrogenphosphate, 8-12 of sulphuric acid potash fertilizer, 1 of lanthanum nitrate, 1 of yttrium nitrate, and 5-7 of cross linker. The compound water retention agent combines biology and physiology characteristics of the potatoes and adopts the moisture retention and slow release property on fertilizer of organic and inorganic water retention agent to improve the property of soil; nutritive elements, a mycorhiza agent, trace elements in the compound water retention agent are reasonably matched to prepare a special compound water retention agent suitable for potato plating in northern area; the compound water retention agent has good moisture retention and can promote anti-drought seedling formation and increasing yield of potatoes.

Description

technical field [0001] The invention relates to a water-retaining agent, in particular to a composite water-retaining agent used in planting potatoes and a preparation method thereof. Background technique [0002] Potatoes are one of the most important food crops in the world and one of the top ten popular nutritious and healthy foods. More than two-thirds of countries in the world grow potatoes, with an output of about 3 billion tons, second only to wheat, corn, and rice. four. [0003] Potato (Solanum tuberosum L.) is an annual herbaceous plant of the family Solanaceae, and its tubers are edible, also known as potatoes, yams, yam eggs, and potatos. Potatoes are rich in nutrition, rich in energy and various nutrients needed by human activities. According to the report of the authority of the United States, only edible whole milk powder and potato products can provide all the nutrients needed by the human body, and potatoes are considered to be a main food in the world foo...
