A method for alleviating diseases and improving yield in water chestnut cultivation

Abstract

The invention belongs to the technical field of water chestnut cultivation and relates to a method of alleviating diseases and improving output in water chestnut cultivation. The method comprises the following steps: after transplanting a water chestnut seedling as a female parent seedling in a field, dividing a plurality of tillering seedlings by the female parent seedling, wherein the female parent seedling grows to obtain female strains; when the number of the average tillering seedlings of all the female strains reaches 6-7, cutting out all cladophylls of the female strains from the bases of the female strains from 2-5cm under the soil surface with a sickle; and then collecting the cut cladophyll to be destroyed out of the field, and performing topdressing to the field within 2-7 days for the strains without the cladophyll. The method has the advantages that infection of stem blight in water chestnut cultivation can be alleviated, ground cladophylls grow in order, underground corms are uniform in distribution, the large fruit rate is high, the output is high, the labor employed is little, and the revenue is great.

Description

technical field [0001] The invention belongs to the technical field of water chestnut cultivation, in particular to a method for alleviating diseases and improving yield in water chestnut cultivation. Background technique [0002] Water chestnut, also known as water chestnut, is a perennial aquatic herb of the Cyperaceae water chestnut, with underground bulbs as edible organs. Water chestnuts are more resistant to storage and can be stored until March-April of the next year. They play a certain role in regulating the supply of vegetables in the off-season and are also one of the export commodities. The cultivation of water chestnuts in this region has a history of hundreds of years, and traditional cultivation methods have been used all the time. In recent years, with the adjustment of the agricultural planting industry structure, the cultivation area and output of water chestnuts have been increasing, but the output per unit area has a downward trend year by year.

Problems solved by technology

The reason is that the traditional cultivars are aging and their species are degraded, and the selection and introduction of them are unscientific.

Second, the cultivation techniques are old-fashioned, and stem blight is increasing year by year

In order to avoid the harm, the local farmers began spraying pesticides from the beginning of September until the end of October, and the number of sprayings reached 6-7 times, and each time they were dispensed, they were mixed with more than 2-3 kinds of pesticides, and the dosage was seriously exceeded. , seriously endangering human health
