Problems solved by technology

If nutrients are not supplemented in time, it will inevitably cause huge losses to the growth and economic output of Scrophulariaceae
In actual production, due to unscientific fertilization methods and periods, the fertilizer utilization rate is low, the cultivation cost is increased, the yield of Scrophulariaceae is not high, the quality of medicinal materials is uneven, and it will also cause pollution and damage to the environment

Embodiment 1

[0028] Preparation of organic basic fertilizer: Select suitable plots for the growth of Scrophulariaceae in Wuling Mountains, Chongqing; added enzyme bacteria (EM LW-2 ) is composed of photosynthetic bacteria, actinomycetes, yeast and lactic acid bacteria, and its mass ratio is 1:0.8:2:1.5. Chicken manure, pig manure and cow manure were purchased from farms near Wulong County, Chongqing City; 3 treatments were set up in the experiment, and the initial moisture content of the piles of the 3 treatments was adjusted to 60%, and the amount of EM bacteria added was 0.3% of animal manure , The pile is in the form of a round pile, with a bottom diameter of about 1.5m and a height of about 1m. If the fermentation is piled up in a ventilated plastic greenhouse, there is no need to cover it with plastic film. Turn over once every 10 to 14 days, and turn the compost 2 to 3 times in total. After the fermentation is completed, take samples. The results are shown in Table 1 and Table 2.

Embodiment 2

[0034] The experiment was carried out at the Scrophulariaceae base in Wuling Mountain, Chongqing. The previous crops in the experimental field were corn, and the soil was yellow loam.

[0035] Preparation of composite bacterial agent: Bacillus subtilis (A), Trichoderma harzianum (B) and Trichoderma reesei (C) were mixed according to the ratio in Table 3 respectively to prepare composite bacterial agent.

[0036] Preparation of compound fertilizer: the compound bacterial agent is mixed with the organic basic fertilizer prepared in Example 1 respectively, and added inorganic fertilizer, wherein, per 100 kilograms of Scrophulariaceae compound fertilizer urea is 1.28~9.76kg, and ammonium phosphate is 3.64~9.4kg , potassium chloride is 2.56~9.28kg, organic fertilizer is 72.4~89.72kg; ZnO content is 200-400mg / kg, B 2 o 3 The content is 90-125mg / kg.

[0037] The number of effective viable bacteria is controlled at 500-800 million / g.

[0038] Fertilization: The plots were arranged i...

Embodiment 3

[0043] The experiment was carried out at the Scrophulariaceae base in Wuling Mountain, Chongqing.

[0044] Adjust the water content of fresh chicken manure to 60±10%, apply film to ferment at room temperature for 15 days (height of heap is 1.0m, width of heap is 4.0m, length of heap is 20m), adding enzyme bacteria (EM LW-2 ), the dosage is 5% of the weight of animal manure, during which the pile is turned 1-2 times. Add inorganic fertilizer, urea per kilogram of Scrophulariaceae compound fertilizer is 1.28-9.76kg, ammonium phosphate is 3.64-9.4kg, potassium chloride is 2.56-9.28kg, ZnO content is 200-400mg / kg, B 2 o 3 The content is 90-125mg / kg; adding compound bacteria agent, the dosage is that the effective number of live bacteria of Scrophulariaceae bio-organic compound fertilizer is 500-800 million / g, wherein the ratio of Bacillus subtilis, Trichoderma harzianum and Trichoderma reesei is The experimental group of (1: 1: 1) is processing I, and the experimental group that...

Abstract

The invention provides a compound fertilizer for radix scrophulariae. The compound fertilizer comprises an organic base fertilizer and an inorganic adding fertilizer. The compound fertilizer is characterized by also comprising a complex microbial inoculant, wherein the complex microbial inoculant is prepared from bacillus subtilis, trichoderma harzianum and trichoderma reesei; and the living bacteria count of the complex microbial inoculant in the compound fertilizer is 500,000,000-800,000,000 / g. According to the compound fertilizer provided by the invention, the pH value of the soil can be improved; the diversity of microbial communities of the soil is improved; the compound fertilizer meets the growth requirements of the radix scrophulariae at various stages, and is comprehensive in variety and appropriate in ratio; the morbidity of the radix scrophulariae is effectively lowered; and the yield and quality of the radix scrophulariae are improved.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a special bio-organic-inorganic compound fertilizer for Scrophulariaceae and a preparation method thereof. Background technique [0002] Scrophularia ningpoensis Hemsl (Scrophularia ningpoensis Hemsl) is a commonly used bulk medicinal material in my country. It is cultivated in both the north and the south of China. It is an important species for nourishing yin and cooling blood. It has the effect of lowering blood pressure and blood sugar. One of the important medicines for tonsils, lymphatic tuberculosis and other diseases, and it is also a traditional export medicinal material in my country. [0003] Scrophulariaceae is an economic crop, which has less strict requirements on soil type, quality, and physical and chemical properties, but has higher requirements on fertilizer ratio and nutrient content. The entire annual growth period of Scrophulariaceae is divided into four stages: seedl...
