High-yield sweet potato cultivation technology

The Yuzhong Potato King, a high-yielding, high-starch sweet potato variety developed by the World Chinese Company through years of meticulous research and cultivation, has received significant recognition. It earned the second prize for scientific and technological progress in Pingqiao District, Xinyang City, and was highlighted at the "China International Agricultural Fair" in 2001 as a notable new sweet potato variety. Additionally, it was acknowledged by the Henan Provincial Bureau of Industry as one of the首批 "agricultural and sideline products processing bases for township enterprises in Henan Province." The provincial, municipal, and district science and technology committees, along with the Youth League, have also recognized it as a "science and technology poverty alleviation fine plant promotion base" and "youth agricultural comprehensive development demonstration base." Our company collaborates closely with experts and professors from the Provincial Academy of Sciences to provide technical support and promote the adoption of these new varieties. As part of this effort, we have been designated as the seedling base for cultivating, reproducing, and promoting new sweet potato varieties in Yunan, under the guidance of the Sweet Potato Research Office of the Provincial Academy of Agricultural Sciences. High-yielding sweet potato cultivation tips: 1. For spring potatoes, the ridge spacing should be 80 cm with a plant spacing of 30 cm, allowing around 2,800 seedlings per mu (Chinese acre), producing approximately 4,000 kg per mu. In summer, the ridge spacing is 75 cm with a plant spacing of 25 cm, resulting in about 3,500 seedlings per mu and yields exceeding 3,000 kg per mu. 2. To achieve yields exceeding ten thousand catties, apply 10 kg of urea, 20 kg of phosphate fertilizer, and 30 kg of potassium sulfate or 50 kg of sulfuric acid fertilizer per mu. On fertile lands, reduce or avoid nitrogen fertilizer application. Excessive nitrogen can lead to vigorous growth, which may necessitate the use of "diaminos," "paclobutrazol," and "chlormequat" sprays to control growth and prevent yield loss. Spring potatoes should be planted horizontally, 2.5-3 cm deep, with three-quarters buried and one-quarter exposed. Ensure uniformity in seedling height during replanting. After spraying, sweet potato expanders are applied for 40 days, followed by sweet potato sprays every 7-10 days in the middle and late stages. Sprays including Dioscin, potassium dihydrogen phosphate, dildoamine, paclobutrazol, chlormequat, etc., are applied four times. 3. If seedlings are not planted within three days of ridge application or are planted within three days after application, herbicide "acetochlor" should be sprayed on dry land before planting. If seedlings are already sprayed, reapply herbicide when transplanting. Both spring and summer potatoes can use sweet potato tops as herbicides. 4. Sweet potatoes are potassium-intensive crops. Apply more potassium fertilizer (such as potassium sulfate). When applying ridges, mix carbofuran and fertilizer to prevent and control underground pests, avoiding yield reduction. 5. Throughout the growing season, do not turn the vines. After overcast and rainy weather, lift them twice daily. 6. Cutting vines in spring potato fields can reduce yields by 30%-40%. 7. Wheat stubble should be inserted diagonally, harvesting after ridging and cultivating for higher yields. Summer potatoes store well and have high germination rates. 8. Key factors for planting seedlings include shallow planting, pressing, watering, and fine sealing. 9. Three critical aspects for sweet potato growth are stable early growth, strong mid-term vigor, and robust late-stage performance. 10. Sweet potatoes can be intercropped with corn, sesame, and tobacco, providing substantial economic returns. (The company provides detailed cultivation information.) From April to September, large quantities of sweet potato seedlings are supplied, with both spring and autumn seasons offering potato seed supplies.
