In recent years, because of its rich nutrition, high medicinal value, and the ability to use both herbs and medicinal herbs, the drug is popular with consumers. Ma yam generally yields 2,500 to 3,000 kilograms of root per mu, and the net income is over 5,000 yuan. When the prices are good, the output value of the high-yield land breaks through ten thousand yuan, so planting yam is a good way for farmers to increase income. High-yield cultivation points are as follows:
First, soil preparation and selection. The selected land plots have high topography, good drainage, and deep sandy loam soil. Slough soil fertilization, filling the bottom. The harder yam yam of disease-free roots was selected for seeding, and a new high-fat membrane (combined with seed coating agent) was used for soaking treatment to repel insects in the ground, isolate virus infection, strengthen respiratory intensity, and increase seed germination rate. .
Second, do 畦 planting. When the temperature is maintained at 12°C and the ground temperature stabilizes above 10°C, planting can be achieved. Before the broadcast, cover the wet sand for 7 to 10 days, cover the plastic film and germinate. Grooves at a distance of 80 cm, width of 80 cm, narrow row spacing of 30 cm, planting depth of 3 to 4.5 cm, spacing between plants is generally 15 to 20 cm, and Mashan Yaozi is tiled in the same direction in the ditch. surface. For budding buds, select 1-2 buds and remove the rest.
Third, field management. After the emergence of Ma yam, the stent should be introduced in time. If there are too many lateral branches, the side vines can be removed and the upper side vines can be preserved. In the early stages of growth, weeding and weeding should be done till the last half of the vine. In the upper half and the full frame, the fertilizers were topdressed one time, and some potassium fertilizers or foliar fertilizers were appropriately chased. At the same time, a new high-fat film was sprayed to increase the stress resistance. When the leaves begin to spread, the herb is sprayed on the foliar roots. Foliar photosynthetic products (nutritions) are transported to the root system to increase the nutrient conversion rate and ripping ability, so that the rootstock rapidly expands and the medicinal content is greatly increased. Ma Shan Yao is a drought-tolerant crop. In order to increase the yield, it should be lightly watered 1-2 times under long-term drought-free weather conditions. In case of rainy weather, it must be drained in time to prevent damage.
Fourth, pest and disease control. Anthracnose is a common disease in the production of yam. Once a lesion is found on the leaf surface, an appropriate amount of mancozeb and a new high-fat membrane foliar spray can be used in the initial stage. Generally, spray is applied once every 7 to 10 days, 2-3 times. can. Nematode is a major insect pest of the yam, the control method is generally used in 5% gram of phosphorus granules 3 kg evenly spread in the planting ditch. (Rain)
