step four, field management: spreading plant ash on the surface of the furrow for 2-3 times 10-30 days after seedling emergence, spreading 300kg of 200-plus-materials per mu each time, dressing for 1 time every 4-5 months, applying 130kg of nitrogen-phosphorus-potassium compound fertilizer to each mu, replenishing water once after dressing each time, and keeping the water content of the soil to be 58-63%;
step five, transplanting: transplanting the seedlings into a sunny land when the seedlings grow to 5-8 green leaves, and inserting branches with the height of 1-1.2m beside each seedling when the seedlings are 15-30cm high;
step six, pinching: removing branches and leaves at the top of the seedlings to maintain the height of the seedlings at 45-60 cm;
seventhly, pest control: and (3) timely removing the diseased plant, irrigating the diseased plant with 800 times of 50% thiophanate methyl liquid or 800 times of 50% sterile wettable powder, and performing primary control on 4-6 days in rainy days and 11-15 days in sunny days.
The invention has the following working principle and beneficial effects: according to the invention, high-quality soil is selected, ventilation and light transmission can be realized in the field, the balsam pear is smashed and then mixed with clear water in the land preparation process, so that tetracyclic triterpenes contained in the balsam pear fruits and seeds are dissolved in water, the disease resistance of the land is enhanced through the tetracyclic triterpenes in the balsam pear, partial insects and germs in the land are killed, and the possibility of possible infection and pest damage of the codonopsis pilosula during planting is further reduced. The adopted base fertilizer and additional fertilizer have higher nutrient contents, compound the growth requirement of the codonopsis pilosula, reduce the occurrence of diseases and insect pests in the growth period of the codonopsis pilosula through scientific disease and insect pest control, and effectively provide the yield of the codonopsis pilosula.
Further, after the land is exposed to the sun in the step one, 38-40kg of calcium cyanamide is sprayed into each mu of land, then the land is covered with a film, and clear water is sprayed into the film. The purpose is that the calcium cyanamide can be decomposed in water to generate liquid cyanamide and gaseous cyanamide, and the pesticide has a wide killing effect on harmful organisms such as fungi, bacteria and the like in soil.
Further, in the step one, base fertilizer is applied to each mu of land, and the base fertilizer comprises: 100kg of decomposed cow dung 105kg, 70-80kg of urea, 20-22kg of zinc sulfate, 35-37kg of ammonium persulfate, 40-45kg of chinaberry bark, 4.5-5.5kg of potassium chloride and 30-35kg of ground phosphate rock.
