Arrowhead cultivation method

Abstract

The invention discloses an arrowhead cultivation method which comprises the following steps of waterlogged compost, wherein swamp mahogany, tea seed residue and peanut shells are ploughed under a plough layer of a breeding land as base fertilizers; seedling, wherein arrowheads are cultivated in the breeding land according to the planting distance of 5 centimeters * 5 centimeters at the early to middle of the March; transplanting, wherein the arrowheads are transplanted to a field from the breeding land at the early to middle of the June; field managing, wherein topdressing is carried out once on the arrowheads after the arrowheads are transplanted for 7-10 days, then topdressing is carried out once every half a month until the early to middle of the August, the final topdressing is carried out at the middle to late of the August, 50-60 kilograms of plant ash and 500-800 kilograms of farmyard manure are applied per mu; field water draining, wherein the water drainage is carried out after the middle of the November, and fruits can be dug out between the late of the November to the early to middle of the December. In the seedling land, the swamp mahogany, the tea seed residue and the peanut shells are ploughed as the base fertilizers and good in fertility, the swamp mahogany and the tea seed residue have a disinfection effect and can eliminate bacteria in the seedling land, growth of weak seedlings in the nursery stage can be guaranteed, the weak seedlings with diseases are prevented from being planted in the field, and causative agents are eliminated substantially.
