Problems solved by technology

[0004] But for now, although mineral fertilizers have more advantages than chemical fertilizers, the processing costs are relatively high, the process is more complicated, and the minerals themselves also contain various heavy metals, which may have a certain impact on the growth of crops

Embodiment 1

[0020] Select natural minerals whose main components are calcite and dolomite as raw materials for water treatment. In the laboratory, use X-ray diffraction spectrum, Raman spectrum and scanning electron microscope to carry out basic phase identification and micromorphological characterization of mineral materials. get figure 1 and figure 2 . The main components of this natural mineral material are calcite and dolomite, the results of semi-quantitative analysis are about 75% and 25% (mass fraction) respectively, and also contain a small amount of iron manganese oxide and quartz (less than 5%). The specific analysis method is as follows:

[0021] A1, material selection: take the above-mentioned natural minerals, pass through a 200-mesh sieve after grinding for subsequent use;

[0022] A2, X-ray diffraction analysis: the sieved minerals are completed on the X'Pert Pro diffractometer (PANalytical Company of the Netherlands), the tube pressure is 40kV, the tube flow is 40mA, t...

Embodiment 2

[0027] For the natural rock mineral that embodiment one provides, utilize Fourier transform to study its infrared emission spectrum, obtain image 3 . The study found that the natural rock mineral material has infrared emission properties at 100°C, including the following steps:

[0028] B1. Weigh 200 mg of sieved natural rock mineral material sample powder, irradiate it under an infrared baking lamp for 5 minutes to remove the interference of oxygen and carbon dioxide in the atmosphere, and press it into a thickness of about 1mm with a diameter of 20Mpa with a tablet press. 13mm disc;

[0029] B2. Place the prepared disc in a cylindrical heater made of copper and fix it with screws;

[0030] B3. Use heating accessories to heat up the cylindrical heater to 100°C, and use the TENSOR series research-grade Fourier transform infrared spectrometer VERTEX80V (Germany Bruker Company) to obtain the range within 400cm -1 ~2000cm -1 The data.

[0031] Such as image 3 As shown, co...

Embodiment 3

[0033] Research the natural minerals of embodiment one on the influence of crop growth by the following steps:

[0034] C1. Cut the natural mineral into cubes with a side length of 1 cm, weigh 1 kg and soak in 100L tap water for half an hour and then filter to obtain mineral water;

[0035] C2, measure 100L tap water and well water without mineral treatment respectively as contrast;

[0036] C3. Utilize mineral water, tap water and well water to irrigate crops, and compare the seed germination rate, growth rate and yield of the crops treated with mineral water, tap water and well water in the same time.

[0037] The results show that the germination rate of the water-irrigated crop seeds after the mineral treatment is significantly improved (see Figure 4 in (a) and (b)). In the two-season planting experiments, it was found that under the same temperature, humidity and light conditions, compared with tap water and well water, the germination rate of green onions, cucumbers, ...

Abstract

The invention discloses a method for promoting the growth of crops and reducing insect damage. The natural mineral materials whose main components are calcite and dolomite are crushed and soaked in water for a period of time, and then the crops are irrigated with the water soaked in the natural mineral materials, which can promote crop growth, reduce insect pests, and increase crop yield. The field test results show that the crops cultivated in water treated with natural minerals not only have higher yields than untreated water, but also have more advantages than untreated water in terms of insect resistance, crop taste, crop growth speed, and crop fineness. . The method of the invention overcomes the unfavorable factors such as soil pollution, heavy metal accumulation, and microbial activity reduction by fertilizers in the past, fully utilizes natural rocks in nature, and has the characteristics of convenient raw material sources, simple operation methods, and quick results. Compared with other chemical fertilizers, Pesticides have many advantages and have broad application prospects in the field of agricultural production.

Description

technical field [0001] The invention relates to crop planting technology, in particular to a planting method for irrigating crops with mineral water to promote their growth, reduce pest damage and increase crop yield, and belongs to the field of agricultural research and application of minerals. Background technique [0002] The growth of crops is inseparable from the nourishment of fertilizers. In our traditional agricultural planting, the most commonly used fertilizers are made of chemical and physical methods containing one or several nutrients needed for the growth of crops, also known as inorganic fertilizers. Including nitrogen fertilizer, phosphorus fertilizer, potash fertilizer, micro fertilizer, compound fertilizer and so on. They have simple ingredients, high nutrient content, fast fertilizer efficiency, and strong fertilizer; some fertilizers have acid-base reactions, generally do not contain organic matter, and have no effect of improving soil and fertilizing. D...
