Method for middle-late-stage cultivation of lotus roots

Abstract

The invention discloses a method for middle-late-stage cultivation of lotus roots. The method includes the following steps: (1) water supply, wherein water is controlled not to cover leaves at the early stage, a field is covered by the leaves at the middle stage, the field is covered by dead leaves at the late stage to be kept moist and warm, and the application amount of nitrogenous fertilizer is controlled to prevent the leaves from growing too vigorously; (2) disease prevention, wherein 2kg of copper sulfate is applied every 667 square meters to kill germs 15 days before planting if decayed lotus roots, lotus roots with yellow cores and lotus roots infected with tan diseases are found every time the lotus roots are planted for three times; (3) tip conditioning, wherein stems are conditioned, namely, the stems are made to grow directionally 15 days after seeding, and the stems can be bent back slightly by hand if the stems are too close to the edge of a weir; (4) deinsectization, wherein egg masses and larvae of prodenia litura are caught and killed manually; (5) harvesting, packaging and storage and transportation. The method for middle-late-stage cultivation of the lotus roots is little in investment and good in economic benefit.

Description

technical field [0001] The invention relates to a method for cultivating lotus root, in particular to a method for cultivating lotus root in the middle and late stages. Background technique [0002] The lotus root in Jiangzhou, Shanxi can be traced back to the Sui Dynasty more than 1400 years ago, and it is called white lotus root. At present, many farmers do not understand that carbon in straw and cow dung can directly assemble carbon, hydrogen, oxygen, and nitrogen into plants under the action of biological bacterial fertilizer. Most people don't know that the three elements of carbon, potassium and boron determine the yield of lotus root, often resulting in large leaves and high stalks, and the yield is reduced by 50% to 90%. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating lotus root in the middle and later stages; not only can avoid the phenomenon of large leaves and high stalks, but also can increase yield...
