Corn interplanting Arisatian farmland income guaranteed
In recent years, in order to increase the farmland utilization rate, some rural households in Anguo City have used the intercropping pattern between Arisaema and Maize to form a cool microclimate of the Araceae, and to fully exploit the advantages of the corn and achieve a good harvest. Arisaema is also known as Pinellia ternata. It is a perennial herb with a plant height of 30-45 cm. It is both male and female. For the past five or six years, the Araceae market has been good. Reproductive production of small Argiope bulbs with seeds, the price of 10 to 15 yuan per kilogram, mu income in the 2000 ~ 4500 yuan (usually 200 ~ 300 kg per mu). I. Araceae cultivation techniques 1. Selection and soil preparation. Arisaema is a dwarf, shallow-rooted plant that is well-behaved and suitable for planting in fertile sandy loam. It is afraid of drought and is afraid of long-term accumulation of water. Hardy, the seedlings can overwinter in the field, but the plants grown in the second year can not overwinter in the fields. Before the planting, select the land according to the Aragon growth habit, combine the land preparation with Mushi or compost 3000-4000 kg, DAP 25 kg (or 100 Mg superphosphate), and apply 15 kg of potassium sulphate mu, and spread the fertilizer and mix it. Tillage is done. Generally, the width and the width are 1.2 meters and 0.3 meters, respectively. The length of the beam is determined by the block, and the convenience of drainage and irrigation is better. The great pheasant species of Araceae, the small loquat plant a line of corn. 2. Arista breeding method. Divided into tuber propagation and seed propagation in two ways. Tuber Propagation: Before and after the "Ching Ming" Festival to the "Gui Yu" Festival, in the entire area of ​​the sorghum, the ditch is 25 cm apart, the ditch depth is 5 to 7 cm, and the plant height is 12 to 15 cm. up. After planting covered with fertilizer and fine soil 3 to 4 cm thick. Small tuber cover soil should be shallow, big tubers should be deep. Planting 40-75 kilograms of tubers and 25-35 kilograms of small tubers per acre. Seed propagation: Seedlings newly planted in the same year can be seeded in autumn or spring. Autumn sowing in the "Early Autumn" Festival, spring broadcast in the "Qing Peng" to "Gu Yu" Festival. Shun the shallow ditch with a depth of 1.5 cm and 10 to 15 cm. Spread the seeds evenly into the ditch (sowing is also possible) and then cover the soil and water. If sowed on the autumn festival, the seedlings can be grown 26 to 27 days and transplanted to Daejeon one year later. 3. Field management. Due to the shallow Xinglong roots, the cultivator should be shallow and should not be deep. It is important to loosen the soil, keep the land loose, and remove the weeds in the field in time. When the height of seedlings is 6 to 9 cm, 1,000 to 1,500 kg of thin human fecal urine is applied per acre combined with cultivator, and then applied again in mid-June (the method is the same as before). In late July, the growth period is prosperous, and 1500-2000 kg of manure is used per acre. In late August, topdressing 10 kg of urea per mu and 15 kg of superphosphate. During the growing season, pay attention to watering, because the roots are not deep, watering should be a small number of times. Pay attention to drainage during the rainy season to prevent drowning. After the flowering of the Arisaema, the inflorescences of the rest of the plants should be cut off in time to preserve the yield. 4. Control pests and diseases. The first is dead-mite: Most of the reasons are caused by the "hot-wound" during the storage of the Arisaus tuber. Therefore, it is necessary to choose a tuber plant that is robust and not “hot†without pests and diseases. The second is viral disease: the leaves of the plants are not shrunk after the disease is felt, and the disease can be used to prevent and treat the gibberellin spray. It is more important to strengthen the management and improve the disease resistance. Third, red spider: If spider mites are harmed from July to September, it can be sprayed with avermectin 3000 times solution or sprayed with 40% dimethoate 1000 times solution. Note that medication is stopped 20 days before harvest. 5. Harvest processing. With the propagation of bulbs, when the autumnal equinox to the leaves of the cold dew season when the yellow leaves planing; seedlings after two years with planing. Shave out the stems and stems of the bulbs, shake the soil, and put them into the sacks (the amount of 1/3 of the sacks is enough). Put the skins on the boards, pour out the water, and use a bamboo knife to scrape the skin of the hollows. , and then it can be dried. Arisaema is poisonous. Avoid entry. Apply some oil to your hands during processing to prevent itchy, reddened skin. After the work is done, wash your hands with soap to avoid poisoning. Second, the corn planting technology selection The current high-yield stable product species, it is best to choose the leaves on the red, stalk thick, not easy to lodging varieties, such as Zhengdan 958, Nongda 108, Daiyu 6, and so on. Sowing in the middle and early May, the bottom pods should be sufficient to ensure full seedlings. In the selected cockroach (small cockroaches), seedlings are planted at a spacing of about 30 cm from each other. The depth of the hole is 3 to 4 cm, and 2 to 3 seeds are placed in each hole. When the height of seedlings is 15 to 20 cm, seedlings are planted at a spacing of 25 to 30 cm and 1 seedling per hole. During the growing period, weeding and weeding are performed in time. In the big bell mouth period, we combine watering to chase one fertilizer, and apply topdressing with urea (20 kg per fern per acre). Attention is also paid to the prevention and control of pests such as corn borers.
