New technology for smooth cultivation of Chuanwu filming
How is Chuanwu planted? Chuanwu is a kind of traditional Chinese medicine plant that can cure diseases such as dispelling wind and getting wet. In recent years, more and more people have planted Chuanwu. Why, because the price of Chuanwu market is good and well cultured, the cost and effort required are not much. Let's learn a test together. Some experts directly perforated the Chuanwu on the waste film after planting corn, and saved a lot of management steps. It was found that Chuanwu also grew well. Let's take a look at this new technology of cultivating light and simple cultivation of Chuanwu.
1. Choose high quality aging resistant mulch
Inferior mulch film produced from waste plastics is not resistant to aging, and is easily broken after being covered by wind and sun. Generally, it is unusable when corn is harvested. In order to realize a mulch film that covers both corn and chuanwu, and to achieve a dual-use membrane, it is necessary to select an aging-resistant mulch film produced by high-quality plastic when planting corn. The width of the mulch film is preferably 80 cm. Good livestock and poultry, to prevent them from entering the ground, try to keep the mulch clean and complete.
2. Adding base fertilizer and applying farmyard manure
Maize is a high-yield crop with high yield and high yield. The high yield of Chuanwu also requires a lot of fertilizer. After the film is covered, the fertilization is inconvenient, especially the farmyard manure can not be applied. Therefore, in order to realize the “double high yield†of corn and Chuanwu, it must be added before the cover film. Base fertilizer, more farmer's fertilizer. Generally, after the land preparation, the ditch is ditched from the center of the reserved row, about 15 cm deep, and more than 2000 kg of high-quality decomposed farmyard manure, 50 kg of high-quality ternary compound fertilizer and 50 kg of ammonium bicarbonate (or 10 kg of urea) per mu. ).
3. Ridge the membrane and grasp the corn management.
After fertilization, take the soil cover fertilizer from both sides of the ditch, the ridge height is about 20 cm, the ridge surface is 60 cm wide, and two rows of corn are planted in each ridge and nest. The plant spacing is 40 cm and the plant spacing is 20-25 cm. After the nest is closed, the ridge surface should be flattened as much as possible. The herbicide is sprayed before the bud, and then the mulch is covered with the mulch. The edge of the film must be tightly sealed to prevent running and running. After the emergence of the corn, the membrane will be ruptured in time, and the rupture should be small. After the nursery is out, the fine soil will be sealed. After the corn seedlings, it is necessary to catch the seedling fertilizer early. In the trumpet period, the hole is applied to the membrane to re-apply the panicle fertilizer, and at the same time strengthen management to prevent lodging. The better the corn grows, the more intact the mulch film is, and the less the weeds in the membrane, the more suitable it is to puncture the Chuanwu after harvesting.
4. Choose the Sichuan Wuliang variety, sowing in the fall
The varieties of Chuanwu are different, and the yield varies greatly. Therefore, it is best to choose the newly introduced Chuanwu variety, and select a medium-sized, uniform-sized, healthy and disease-free, non-invasive Chuanwu seed. Before sowing, the Chuanwu seed was sprayed with the anti-heavy agent “Enyibi†to reduce the occurrence of soil-borne diseases. Alpine corn is generally harvested in the fall of October, and after the corn ear is harvested, it is necessary to cut the stalks in time. Chuanwu began to be planted in November, and the alpine region must be broadcast before the soil is frozen. When planting, use a wooden stick to punch holes in the old film covered with corn. The hole depth is about 20 cm, and the pore size is convenient for the insertion of the Chuanwu seed. 3 rows per hole, the hole spacing is kept at about 20 cm, and each hole is inserted into a seed of Chuanwu. When planting seeds, the roots should be "back-planted" with the heads down and bottom up, and then seal the holes with fire manure or fine-grained farmyard manure. Reserve line cultivation, generally planting 4,500 to 5,000 holes per acre, about 100 kilograms of Chuanwu.
5. Spray paclobutrazol to prevent Chuanwu from lodging
Punching Chuanwu on the old membrane, the management after sowing is relatively simple, mainly to catch the topdressing and anti-falling, disease prevention. If the amount of base fertilizer is sufficient when planting corn, you can not catch the seedling fertilizer. Before the flowering of Chuanwu, you should apply 30-40 kg of ternary compound fertilizer per acre. In the later stage, combined with anti-falling and disease prevention, appropriate application of foliar fertilizer to supplement plant nutrients. The soil covered by the mulch film is loose, and the planted Chuanwu is easy to fall. In the past, Chuanwu was mainly used for capping and smashing, which was time-consuming and labor-intensive; now it is possible to switch to chemical regulation, that is, before the buds of Chuanwu, the spraying of the paclobutrazol solution with a concentration of 50-100 mg/kg is 1 or 2 times.
The key to the prevention and treatment of Chuanwu disease is to select suitable areas and plots for planting, and to do a good job of disease-free seedling base construction, seed treatment, formula fertilization, and crop rotation. If downy mildew, sclerotinia, powdery mildew and other diseases occur, bactericides such as carbendazim, chlorothalonil and thiophanate-methyl may be sprayed at the early stage of the disease. Reserves are cultivated, and other crops such as potatoes can be interposed between Sichuan and Wuxing to increase income.
The above is all the main points about the new technology of Chuanwu cultivation. If you have such a suitable cultivation environment there, you can also test it yourself, but it is recommended to follow the guidance of experts!
