Technical essentials of the new mode of "one kind of three harvests" of lotus root

Honghu, the hometown of lotus root, used to adopt the traditional mode of "one harvest" of lotus root. Lotus farmers grow lotus and get lotus roots, harvest lotus seeds in lotus seed fields, and harvest lotus roots in lotus fields. What is the result?. Lotus root listed concentrated, peddlers card prices, income reduction, lotus farmers often suffer "dumb losses." In Honghu City, combined with the market demand and the growth characteristics of lotus root, the innovative model of "three harvests" of lotus root is put forward, that is, lotus root belt, fresh lotus root, dried lotus seed or lotus root field can be harvested in the second year of lotus seed field. Fresh lotus root products can be supplied to the market all the year round, and lotus farmers can have economic income all the year round. This new model was successfully tested in Wanquan Town last year, and this year it has been popularized in Honghu City with an area of more than 50,000 mu and an income of about 5000 yuan per mu. The key technology of this new model needs to pay attention to the following points: the characteristic of this model is to determine the planting structure according to the market demand, and then to decide how to fertilize to promote growth and benefit according to the need. The main technical points are as follows: first, there must be high-quality and high-yield varieties suitable for local cultivation, or seed lotus or lotus root; secondly, according to the current market situation, determine the product structure, or lotus root-fresh lotus root-dried lotus seed, or lotus root-green lotus root-withered lotus root; then, adjust the proportion and quantity of products. For example, this year, the lotus root market is good, the price is high, and there are leading enterprises to protect the purchase price, it is necessary to determine more production of lotus root. Third, the management after determining the product structure. If you need to produce more lotus roots, then it is necessary to apply more base fertilizer, more topdressing, more lotus roots in the lotus root fields, so that the lotus root fields produce more lotus roots and produce high-quality lotus roots. If the price of fresh lotus canopy is good, and the price of green lotus root is also high, you can consider stopping picking and drawing lotus root in mid-June and applying topdressing again at this time, so that lotus canopy grows in lotus field and lotus root grows in lotus field. Fourth, pay attention to harvesting and topdressing. In early July, lotus canopy can be picked or green lotus roots can be excavated; for each batch of lotus canopy picked in the lotus field, topdressing is applied to facilitate the growth of lotus canopy in the later stage, and finally dry lotus seeds are stored in the lotus field and withered lotus root in the lotus field. At that time, the price of dry lotus seed and withered lotus root also increased due to the decrease of market supply, while lotus farmers made great profits in the three production stages of lotus root stage, fresh lotus root stage, green lotus root stage, dry lotus seed and withered lotus root stage.
