Abstract

The present invention relates to active solid water capable of slow releasing a water content, increasing nutrients and being used for the seedling protecting growth of plants in dry land and a productive method thereof. After 15 to 30% of weathered coal is pulverized, the weathered coal is uniformly mixed with 15 to 20 % of ammonia water and 10% of concave-convex rod powder, and then, a mixture is put into an ammonification pool to carry out reaction and curing so as to prepare ammonium humate. The powdery ammonium humate is added with 40 to 60% of water to be stirred and uniformly mixed so as to make the ammonium humate saturate and absorb water, and finally, a finished product is formed by freeze-drying or is directly formed. Because the ammonium humate prepared in this way, is similar to a spongy body having excellent water absorbability and containing various nutrients, when the ammonium humate is embedded into roots of tree seedlings or crops, water contents and nutrients can be supplied to the plants in dry land for a long time, and thereby, the survival rate of the plants can be greatly improved.

Description

Active solid water and production method thereof

Technical field

The present invention relates to dry land crop plantation and tree planting field, particularly a kind ofly act on plant root and have the retaining slowly-releasing, preserve moisture and the active solid water and the production method thereof of additional nutrient effect.

Background technology

Water is the primary condition of plant life.Be faced with water shortage problem at present all over the world, China's arid and desertization problem are very outstanding, such as mountain area, south, Ningxia and some desertization serious area, and annual rainfall is less than 300mm, and human livestock drinking water all is a problem, and trees are difficult to survive especially in plantation.People take water-saving irrigation for this reason, measures such as container water conservation and dripping irrigation moisturizing, but this for live at the mercy of the elements, that lack of water is serious, seedling all can't survive is regional of no avail.Moreover the manual watering also has following shortcoming: the one, and labour intensity is big; The 2nd, as the deficiency of watering, the soil moisture inequality also can cause soil block sclerosis, plant can not take root and be difficult to survive; The 3rd, as it is too many to water, plant root rots drowned easily.

Summary of the invention

The object of the present invention is to provide a kind of can in the long time, moisture content and nutrient being provided, keeping a full stand of seedings and urge living active solid water and production method thereof to plant in right amount as the fertilizer direct-burried in plant root.

Technical scheme of the present invention is such:

A kind of active solid water, it is characterized in that this active solid water is mixed by ammonium humate and water after, form through freezing shaping or straight forming, wherein ammonium humate is made by weathered coal, ammoniacal liquor and attapulgite, composition of raw materials is (percentage by weight):

A. water 40-60%

B. weathered coal 15-30%

C. ammoniacal liquor 15-20%

D. attapulgite 10%.

The preparation method of active solid water is characterized in that taking following processing step:

(1) get the raw materials ready by following composition of raw materials (percentage by weight):

A. water 40-60%;

B. weathered coal 15-30%;

C. ammoniacal liquor 15-20%;

D. attapulgite 10%,

(2) make ammonium humate: weathered coal is pulverized, added ammoniacal liquor and attapulgite then, react slaking and make ammonium humate thereby put into the ammonification pond after mixing;

(3) the powdery ammonium humate is added water and mix to saturated, freeze forming or direct press forming make the active solid water finished product thus.

The contained ammonium humate of active solid water of the present invention is actually a kind of thing of similar cavernous body, and water is adsorbed in wherein.It is embedded in plant roots, and water can soak into soil by slowly-releasing with the rising of ground temperature, absorbs for crops, trees, and the plant that takes root in solid water can directly absorb especially.Ammonium humate accelerated decomposition then in soil meanwhile transforms microorganism in the soil on the one hand for the plant absorbing utilization, on the other hand the N, the P that are rich in of ammonium humate itself ₂O ₅, K ₂Nutrients such as O, B, Fe, Zn are also in time utilized by plant absorbing, have the effect that kills two birds with one stone.

Evidence uses active solid water can improve emergence rate and the survival rate of crops and sapling greatly in arid and arid area.

Active solid water can use as follows: 1) in annual 3-6 month, when planting tree seedlings, with the buried 10-20cm of its root sapling, the trees that survived also can be used equally, general every cubic metre of soil is imbedded the 3-6kg active solid water, and 3kg can guarantee that it survives for sapling; 2) use active solid water to ditch earlier for big strain crop or economic crops, below the buried 10cm of active solid water, then the earthing ridging, the lid mulch film, again with the both sides sowing of artificial active water in being embedded in soil or directly seed is broadcast on active water all can, can guarantee crops such as corn, watermelon thus.Even under the situation of arid, soil moisture content difference, also can one broadcast full stand.

Embodiment

Below in conjunction with three specific embodiments active solid water of the present invention and manufacture method thereof are further described, and by the listed experimental data of table 1 to active solid water three counties in Ningxia trial effect make additional remarks, I, II, III represent embodiment 1,2,3 three kind of active solid water that prescription is made respectively in the table, and the CK representative is without traditional planting patterns of active solid water.

Embodiment 1 (I number prescription active solid water): (1) pulverizes 15% weathered coal, and the ammoniacal liquor of adding 15% and 10% attapulgite are poured the ammonification pond into the agitator mixing and carried out slaking reaction, thereby can make ammonium humate.(2) water of adding 60% carries out abundant stirring and evenly mixing in the powdery ammonium humate, makes the saturated suction of ammonium humate, then it is sent into the refrigerating chamber freeze-drying and is shaped, and the packing warehouse-in can be sold at last.

Embodiment 2 (II number prescription): (1) pulverizes the ammoniacal liquor of adding 20% and 8% attapulgite with 20% weathered coal, pours the ammonification pond into the agitator mixing and carries out slaking reaction, thereby can make ammonium humate.(2) in the ammonium humate of powdery, add the water of 2% attapulgite and 50% and abundant stirring and evenly mixing again, make the saturated suction of ammonium humate, send into the refrigerating chamber freeze-drying then and be shaped, can sell after the packing.
