Abstract

A green dry lotus root planting method is characterized by comprising the steps: (1) establishing a leakproof lotus root pool, spreading a mixture of mellow soil, an organic fertilizer and bean meal in the thickness of 30-40 cm, pouring uncontaminated underground water to the lotus root pool, and enabling that the depth of water in the lotus root pool is 7-10 cm; (2) planting lotus roots after the Grain Rain season: selecting seed lotus roots, which are large in sizes, flourishing in sprouts and free from scars, with the planting density of 500-600 kg per mu and row spacing of 2-3 m, and enabling the heads of the seed lotus roots to be upwards; (3) 15-25 days later after the planting, pouring water after seedlings of the seed lotus roots sprout, and maintaining the water level to be 10-20 cm; (4) in the dry lotus root seedling and assimilated organ growing periods, regularly removing aquatic weeds, turning heads of the seed lotus roots, picking floating leaves and preventing wind; (5) in the mature lotus root period, maintaining water in the lotus pool to be 10-15 cm deep, and preventing aphids and lotus root maggots; (6) after picking the lotus roots, beginning the winter management of the lotus root pool, uniformly replenishing the organic fertilizer, and then pouring water till the depth of the water in the lotus root pool is 25-30 cm.

Description

A kind of cultivation method of green xerophyte lotus root

Technical field

The invention provides a kind of cultivation method of green xerophyte lotus root, belong to cultivation of plants technical field.

Background technology

Lotus rhizome is in all age almost without any technical requirement, be main by self-sow completely in lake region or pond, the defect of this planting patterns of natural environment difference of growth is: water quality inferiority, and water level is indefinite, and soil nutrient easily runs off, earth layer depth, not easily fertilizing management, water temperature and low temperature not easily manual control, the natural environment of growth is poor, yield poorly, quality is also poor.

Summary of the invention

The object of this invention is to provide and a kind ofly can overcome above-mentioned defect, can improve the yield and quality, make lotus rhizome reach the cultivation method of the green xerophyte lotus root of food standard.Its objective is and like this to realize:

A cultivation method for green xerophyte lotus root, is characterized in that adopting following steps:

(1), set up antiseep lotus root pond, the mixture of tile in lotus root the pond mellow soil of 30 ~ 40 cm thicks and fertilizer, dregs of beans, then pours into pollution-free underground water, makes lotus root pool inner water deeply remain on 7 ~ 10 centimetres;

(2), after grain rains plant, select that lotus root is large, bud is prosperous, seamless kind of lotus root, planting density every mu lotus root field with 500 kilograms ~ 600 kilograms kind lotus roots, line-spacing 2 ~ 3 meters, lotus root head-up;

(3), plant rear pouring water after kind of lotus root also seedling for 15 ~ 25 days, keep water level 10 ~ 20 centimetres;

(4), at the seedling growth stage of non-irrigated lotus root and assimilation organ growing period, often carry out except pasture and water, return lotus root, pluck floating leaf, windproof;

(5), in one-tenth lotus root period, dark 10 ~ 15 centimetres of lotus root pool inner water is kept, prevention aphid and lotus root maggot;

(6), adopt lotus root after enter the winter management in lotus root pond, evenly supplement fertilizer, then to pour water to lotus root pool inner water dark 25 ~ 30 centimetres.

The cultivation method of described green xerophyte lotus root, in lotus root pond, fertilizer, the dregs of beans amount of discharging are every mu of 7 cubic metres of fertilizers and 150 kilograms of dregs of beans, and uniform broadcasting, revolves thin leveling with rotary tillage pears.

The cultivation method of described green xerophyte lotus root, plant kind of lotus root time, set up diagonal shallow ridges by line-spacing 2 ~ 3 meters, ditch depth 13 ~ 17 centimetres, kind of lotus root kind head-up tilted to imbed in earth, mutually the staggered plantation of lotus root kind before leaving.

The cultivation method of described green xerophyte lotus root, if when becoming lotus root to occur aphid and lotus root maggot for a long time period, the dimethoate emulsion of the spray dilution 1000 times that eliminates aphis a time, control lotus root maggot can every mu execute the control of double centner albarium.

The present invention compared with prior art, its difference is exactly the standard-required of the present invention in strict accordance with green non-pollution Vegetable produce, change the history of lotus rhizome self-sow in the past, effective manual control is implemented in whole cultivation management process, output significantly improves, the general per mu yield of the hollow lotus root in lake about 2000 kilograms, and non-irrigated lotus root per mu yield can reach 5000 ~ 6000 kilograms, its quality also improves greatly, through 7, Ministry of Agriculture's food quality supervision verification test center (Huaian), index is chemically examined, all reach the standard of pollution-free food, and the hollow lotus root in lake only has five indices qualified.

Embodiment

1, the rectangle ne-leakage lotus root pond of 2500 square metres is set up, the thick plastic film of one deck 10 ~ 12 is all laid in the bottom in lotus root pond and sidewall for preventing seepage, then tile the neutral mellow soil of 35 cm thicks, again by 7 cubic metres every mu corruption chicken manures and 150 kilograms of dregs of beans, uniform broadcasting, revolve thin leveling with rotary tillage pears, finally pour into pollution-free underground water, make lotus root pool inner water deeply remain on 9 cm;

2, planting is after grain rains, selection selects that lotus root is large, bud is prosperous, seamless " Bai Liante " board kind lotus root, first in lotus root pond, set up diagonal shallow ridges by line-spacing 2.5 meters, ditch depth 13 ~ 17 centimetres, kind of lotus root kind is head-up tilted to imbed in earth, the staggered plantation of phase lotus root kind before leaving, planting density every mu lotus root field is with 550 kilograms of kind lotus roots, and by the limit row of pond bank, lotus root head should towards in pond, to reduce back lotus root, within about 20 days, plant afterwards lotus root also after seedling controlling water level at 16 centimetres;

3, non-irrigated lotus root growth management: in seedling growth stage, removes pasture and water in time to increase light transmission, improves photosynthesis; At its assimilation organ growing period, often carry out except pasture and water, return lotus root, pluck floating leaf, windproof, return lotus root and carry out in the afternoon; In one-tenth lotus root period, keep dark 10 ~ 15 centimetres of lotus root pool inner water, prevention aphid and lotus root maggot, if when there is aphid and lotus root maggot for a long time, the dimethoate emulsion of the spray dilution 1000 times that eliminates aphis a time, control lotus root maggot can every mu execute the control of double centner albarium;

4, after adopting lotus root, enter the winter management in lotus root pond, evenly supplement fertilizer, then to pour water to lotus root pool inner water dark 25 ~ 30 centimetres.The service life in a lotus root pond can reach more than 30.

For increasing economic efficiency, can raise together with by lotus root fish, purifying water.
