On the afternoon of April 11, the sky over Yangling Agricultural Science City was covered with dark clouds, located in the sweet potato industry base of Yangling Modern Agricultural Demonstration Park, the sweet potato seedlings of "Qinshu No. 5" were growing vigorously, and Zhu Weibing, senior agricultural technician and general manager of Yangling Golden Potato Seed Company, and several farmers were working hard. "Recently, it is the peak season for the sale of seedlings, the weather is uncertain, it is necessary to raise and lower the roller blinds in time to avoid affecting the storage of seedlings due to temperature changes." Zhu Weibing had just come out of the ground, his clothes and trouser legs were stained with dirt, and he walked quickly, shuttling between several greenhouses, and he had to check the seedlings before it rained.
"Teacher Zhu, I want to order 5,000 seedlings, is there still any now..." Just back to the office, Zhu Weibing's mobile phone rang non-stop, recently due to the ups and downs of the epidemic, the order of sweet potato seedlings has reached a tight juncture, the harvest site is busy, and after a while, the wind and dust rushed to two Qianxian farmers, with an urgent inquiry, "How is this year's seedlings?" Zhu Weibing responded with a smile, "Rest assured, they are all detoxification seedlings, and the quality is no problem." ”
"Cut from the bottom of the leaf bud, the seedlings are not diseased." In the face of market demand for replacement and transformation, Zhu Weibing's improved planting method has a prominent effect. "We cut the seedling stems from 3 to 5 cm above the ground, and cut off the part above the ground to be healthy seedlings." Zhu Weibing introduced that they used the "horizontal improvement cuttings" technique to plant, also known as "one insert, two lying down, three heads": the roots of sweet potato seedlings are rooted in the soil, the stems and leaves are buried horizontally into the soil layer, leaving only the "two leaves and one heart" part outside the soil. "Deep planting to protect seedlings, shallow burial of knots." This 'horizontally improved cuttings method' is summed up by combining the traditional oblique planting method, direct planting method and flat planting method, which can not only ensure the survival rate, but also effectively increase the amount of potatoes. ”
"Last year, I bought 4,000 seedlings, yielded nearly 6,000 catties per mu, and earned more than 10,000 yuan per mu, and everyone who saw it envied it." In the afternoon of the same day, in the process of waiting for the new seedlings, Hou Kuanmin, a farmer in Qianxian County, was solid-minded. "I have been ordering Teacher Zhu's sweet potato seedlings for more than 10 years, and the seedlings can be planted when they are taken back, and the yield is produced that year, and the economic benefits are considerable." Hou Kuanmin said with a happy face, "No, this year many farmers in the surrounding counties and districts have come to order seedlings, and my friends and I hurriedly ordered more than 4,000 seedlings, and by the way, we went to Teacher Zhu to learn some new technologies." ”
In his spare time, talking about the process of sweet potato seedlings, Zhu Weibing opened the conversation box. The "Qinshu No. 4" and "Qinshu No. 5" series of sweet potatoes were selected and bred by his father, Zhu Junguang, a famous sweet potato breeding expert at Northwest A&F University, and this variety has a long reputation and is favored by farmers. Zhu Weibing said that on the basis of his father's breeding, he focused on the market-oriented breeding of sweet potato seedlings, of which the "Qinshu No. 5" variety has the characteristics of high yield, good resistance and good character, which still accounts for 80% of the planting area in Shaanxi Province, and the promotion benefit is about 1.5 billion yuan.
Breeding, germline health and soil issues are the problems that hinder industrial development. For decades, Zhu Weibing has devoted himself to research, from an entrepreneur to the chairman of the Shaanxi Sweet Potato Industry Technology Innovation Strategic Alliance, setting up a laboratory, cultivating test tube seedlings, improving detoxification and breeding technology, and maintaining the stability of sweet potato seedlings. In addition, he also cooperated with experts from Sinon University to develop water-soluble carbon-based nutrient fertilizers, which not only meet the needs of plant growth, but also play a protective role in the soil.
"Through detoxification technology innovation, greenhouse cultivation and other methods, we have made the varieties of seedlings forever young." Zhu Weibing told reporters that the "Qin potato No. 8" he himself selected and bred, red skin and red meat, soft and sweet taste, anti-black spot disease, good storage, mu production capacity of about 4,000 kilograms. "Solving the difficulties in the development of the sweet potato industry is the process of improving the industrial chain, in the face of the change of the masses from eating enough to eating well, only by continuously improving the quality and efficiency of the industry can we ensure that sweet potatoes become the fragrant food for farmers to get rich."
