How to plant Hu Aishan? On-site management in Hu Aishan
2. Planting: Sow after the vernal equinox, ditch 6 ~ 10 cm deep in the border and plant in two rows. The row spacing is 25 ~ 30 cm, and the spacing between plants is about 20 cm. Put the cultivated rhizome or tuber flat in the ditch, and then cover the edge with soil.
3. Field management: mowing and weeding: After planting in Hu Aishan, several seedlings often grow on each stem. If there are too many seedlings, the plants will be thin. Therefore, when the seedling length is about 30 cm, some seedlings and branches on the seedling should be properly removed, leaving only 1 ~ 2 strong seedlings to ensure the robust growth of the plant. In addition, in the hot and rainy season, the growing season in Hu Aishan is about five months, so the soil is easy to harden and weeds grow fast. Therefore, it is necessary to strengthen intertillage weeding to ensure the effective supply of fertilizer.
4. Topdressing: Hu Aishan is a fertilizer-loving crop. In addition to adequate base fertilizer, it needs to be topdressed many times to meet its nutrient requirements. The first combination of weeding. Top dressing 500 kilograms of thin manure and urine per 667 square meters. The second and third sessions were held in June and July respectively. Apply 1500 kg of human excrement or 5 kg of urea every 667 square meters to promote the vigorous growth of plants. For the fourth time, in early August, 667 square meters were mixed with 1000 kg manure and 50 kg peanut bran to cultivate the soil to promote the growth of underground rhizomes and increase the yield.
5. Hedgehog Head: Hu Aishan is a twining herb. After the seedlings grow to 20 cm, small bamboo strips can be inserted into the border to form a fence for the seedlings to grow upward, which is beneficial to ventilation and light transmission between plants, enhance photosynthesis and promote rhizome growth. When the vines of Mount Hu Aishan grow to the top of the fence, the terminal buds are removed to promote the growth and branching of some lateral buds. Increase the area of photosynthesis to facilitate the production and accumulation of nutrients.
6. Irrigation: Hu Aishan does not need irrigation in most growing periods, but if the weather is dry and the soil water content is low, it needs proper irrigation. Irrigation should use furrow irrigation, so that water can penetrate into the border soil, and no water can accumulate.
7. Pest control: There are not many pests in Hu Aishan, mainly diseases, such as anthracnose and brown spot. Prevention first, combining prevention with elimination. Seeds can be disinfected by soaking in 50% thiophanate 1500 times solution for 3-5 minutes, or spraying10 ~150 bordeaux solution continuously every15 days after emergence. After the onset, the diseased leaves should be removed in time, burned, and sprayed with 65% zineb 500 times solution or 50% Tobezin 65,438+0,000 ~ 65,438+0,500 times solution every 7 days for 2 ~ 3 times in a row.
