Coptis in the name, the earliest in "Shen Nong's Materia Medica", said: "top grade, a Wang Lian." "Pharmacological" also known as "branch even". Coptis mainly medicinal plants, the country used berberine as the main raw material, developed a large number of proprietary Chinese medicines, but also developed Coptis series of cultural tourism products, such as berberine, aprotrichia stem dishes, berberine feet, bath health products Wait.

Second, forestry intercropping: suitable for sandy loam temple planting, the annual spacing of white poplar 10 meters, the use of ditch, mantle planting, 2-3 years out, breast diameter can grow to 4-6cm, tree rows sowing wheat and corn.
Third, the characteristics of coating urea and use of technology:
1, the early stage fertilizer effect is slow, stable in the middle period, long aftereffect.
2. Less loss of N and higher fertilizer utilization.
3, contains a variety of trace elements required by the crop.
4, can reduce the number of fertilization.
5, topdressing more than normal urea 5-7 days in advance.
Fourth, the physiological effects of rare earths on crops and the use of methods: The rare earth is not a fertilizer, can not replace N, P, K fertilizer or trace elements, but can be used with them and pesticides. Physiological effects:
1, to promote the emergence of seed germination,
2, to promote crop growth and development,
3, increase crop yields and improve quality. Application method: 15-150 grams per acre, suitable for 0.01-0.05% agricultural, can be soaked, seed dressing, spraying, rooting.
Fifth, the use of corn and zinc fertilizer technology: Corn is more sensitive to zinc crops, zinc deficiency early after the emergence of "white leaf disease" harvest, ear tipping. One acre of input -2 yuan, 30-40 kg per mu increase, when the soil effective zinc is less than 0.5ppm, the application of zinc fertilizer has a significant effect, commonly used zinc fertilizer for zinc sulfate, can be seed dressing, soaking, spraying.
VI. The deeds of the sweet potato king: Fu Wanlong was awarded the title of “Top Ten Farming Master†by the year of 1997 in Bozhou City, and is the representative of Botou City’s 4th and 5th National People’s Congress. In 1997, he introduced 52-7 sweet potatoes, 16 acres, the output value of 24,000 yuan, 98 land contracted more than 30 acres, all using plastic film covering technology, the middle - 7 sweet potato 15 acres, 10 acres of Eagle pepper, Yi No. 1 sesame 3.5 acres, Peanut No. 4 peanuts 2.5 acres, a total of 50,000 yuan, under his lead, in 1998 paid the village to plant 210 acres of sweet potatoes, only this one can increase income of 100 million yuan.
Seventh, the late sowing wheat high-yielding measures: The late sowing wheat mainly has the short parturition period, the low rate of tillering and ear formation, the short plants, the deep burial of the tillering section, and the late maturity.
1, the attack is a fine site preparation.
2. Change the deep fertilization to appropriate shallow fertilization.
3, change the yellow pods sowing for fleas sowing.
4, reclassification of varieties for the early half winter varieties.
5, change the broadcast to shallow broadcast.
6, change the thin planting to planting.
7, change the frozen water is not poured frozen water or frozen water.
8. Change to not cultivator for early cultivator, fine cultivator.
9, change the weight to give back to green for the promotion of health promotion.
10, get up early to get up and water for late pouring.
Eight, wheat water-saving cultivation techniques: With the rapid decline in groundwater levels, water has become a limiting factor in the further development of wheat production, so the development of water-saving wheat cultivation, improve water resources benefits, may have great practical significance. Water-saving irrigation includes two aspects: water saving for engineering and water saving for agriculture and aquaculture. Saving water for the project:
1, channel seepage.
2, channel water.
3. Level land. The festival does not:
1, increase fertilization, fertility is the basis for water conservation.
2. The selection of suitable varieties is a prerequisite for water conservation.
3, the appropriate irrigation period is the key to improving water resources.
4. The ration of fertilizer and water is the core of improving fertilizer efficiency.
Nine, biological potassium fertilizer applied to wheat to obtain significant results: the general lack of available potassium in our soil, resulting in imbalance in N, P, K ratio, is one of the main factors limiting wheat production, so biological potassium fertilizer used in wheat seed dressing, to obtain significant Increase production effect. Promote plant growth and development, plant height, single planting, effective public access, have significantly increased, while promoting the development of secondary root increased by 0.5-2, the root is long and thick, increased yield than the control 41.3 kg.
10. Careful cultivation of aloe vera: Aloe vera is a new star in the flower industry, covering the fields of medicine, Chinese medicine, daily chemicals, ecology, etc. The overall prospects for opening must be good. But for ordinary farmers, they must be careful when selecting aloe. Yes:
1, Aloe's consumer market has not yet fully opened.
2. In recent years, supply and demand in the aloe market has been saturated, and the unit profit has declined.
3. The development of aloe vera with the small-scale peasant economy cannot be adapted to the future market. We must follow the road of industrialization of companies and farmers.
11. New corn varieties: Shendan 16 was selected from Shenyang Academy of Agricultural Sciences. Medium-term breeds, with a fertility period of 00 days, a plant height of 2.5-2.7m, and mature and well-organized live rods, are species with large spikes and high yields. In 2003, the yield of the seven varieties organized in our city was 615 kg per unit. Acres, meanwhile, have strong resistance to insects, and are basically free of H. japonica. However, this species has a high plant type and lodging in another year. It must be planted reasonably and leave 3000-3500 strains per mu.
I. Introduction of Botou Red Zizao Association in Botou City: The Zhuang Zhuang Red Date Association is a non-governmental organization. Zhang Hongchen is the president of the association. It implements unified use of biological pesticides, conducts pollution-free monitoring, and unifies sales.
2. Introduction to the pollution-free detection room in Botou City The facilities in the pollution-free detection room in Botou City are fully equipped. The monitoring staff consists of two senior agronomists and one assisting farmer. The operation is strict and standardized, and the test results are basically correct.
Third, pollution-free agricultural products (vegetables, fruit) routine testing items: routine testing items: organophosphorus pesticide residues and nitrate content.
Fourth, pollution-free vegetable production techniques
1, increase organic fertilizer
2. Keep vegetables away from polluted areas and roads.
3. Use low toxicity and low residue pesticides.
4. Use bio-fertilizer to reduce chemical fertilizer input.
5, rational use of chemical fertilizers to reduce fertilizer input.
6, used in machine fat
7. Promote the use of foliar fertilizers.
5. Several efficient models for intercropping of jujube grain in Botou City Dates - Wheat - Soybean jujube - Wheat - Millet date - Peanut 6. Current pattern of several intercropping patterns of pears and pears - Watermelon - Cotton pears - Chunganlan - Soybean Pear - Sharp Pepper VII. Production of Non-environmentally Harmful Fruits How to Minimize Fertilizer and Pesticide Residues
1. Reuse Organic Fertilizer
2, reduce the number of medication and dosage
3. It is forbidden to use highly toxic pesticides, biological pesticides, or physical control.
4, reduce fertilizer

Meishen, Tuyu special and Gong preparations.
Planting and cultivation techniques
First, jujube grain intercropping cultivation techniques: suitable for water slightly alkaline planting, can get thousands of dollars in the tree, the benefits of the tree under the weight of grain. Jujube tree selection 15 + or -3, spacing 3.5-4 meters, jujube tree line between the planting crops, jujube and intercropping area of ​​3:1 ratio, left and right sides of the trunk to stay 1 meter wide nutrient deputy (tree tray), nutrition With the exception of belts, the upper glutinous species of wheat and the lower pod crops were sowed in soybeans, sweet potatoes, and far-crown area seed millet in the jujube tree near the crown (2 meters outside the crown).
