Abstract

The present invention provides a cultivating technology for green xerophyte lotus roots, which adopts the following steps: (1) a leak-proof lotus root pool is established; mellow soil with the thickness of 30 to 40 centimeters and the mixture of organic fertilizer and bean meal are tiled in the leak-proof lotus root pool, and then underground water without pollution is filled, so the depth of water in the leak-proof lotus root pool is maintained within 7 to 10 centimeters; (2) high-quality lotus roots are selected and planted after grain rain, planting density is 5000 to 6000 kilograms of lotus roots per mou of lotus root field; (3) during the growth period of seedlings and assimilation organs of the xerophyte lotus roots, float grass remove, lotus root return, floating leaf pick and wind prevention are frequently carried out; (4) in the forming period of the lotus roots, the depth of water in the leak-proof lotus root pool is maintained within 10 to 15 centimeters, and aphids and lotus root maggots are prevented; (5) for the management of the leak-proof lotus root pool in winter, the leak-proof lotus root pool is uniformly replenished with the organic fertilizer, and then filled with the water until the depth of water in the leak-proof lotus root pool reaches to 25 to 30 centimeters. The present invention changes the growing environments of the original lotus roots, overcomes the defects of hard fertilization, hard ground temperature and water temperature control, low yield and bad quality and has advantages of high yield of planted lotus roots and good quality.

Description

The cultivation method of green xerophyte lotus root

Affiliated technical field

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

Background is recorded and narrated

Lotus rhizome does not in all age almost have any specification requirement, in lake region or pond, be main by self-sow fully, the defective 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, the earth layer depth, be difficult for fertilizing management, water temperature and low temperature are difficult for artificial control, and the natural environment of growth is poor, yield poorly, quality is also poor.

Summary of the invention

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

A kind of cultivation method of green xerophyte lotus root is characterized in that adopting following steps:

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

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

(3), plantation back treated that kind of lotus root also poured water behind the seedling in 15～25 days, kept 10～20 centimetres of water levels;

(4), at the growth of seedling phase of non-irrigated lotus root and assimilation organ growing period, often remove pasture and water, time lotus root, pluck floating leaf, windproof;

(5), becoming lotus root period, keep dark 10～15 centimetres of lotus root pool inner water, prevention aphid and lotus root maggot;

(6), adopt the winter management that enters the lotus root pond behind the lotus root, evenly replenish fertilizer, pour water to the lotus root pool inner water dark 25～30 centimetres then.

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

The cultivation method of described green xerophyte lotus root when planting kind of lotus root, is set up the diagonal shallow ridges for 2～3 meters by line-spacing, and 13～17 centimetres of ditch depths will be planted the lotus root kind and head-up be tilted to imbed in the earth, the staggered plantation of lotus root kind before leaving mutually.

The cultivation method of described green xerophyte lotus root, if when becoming lotus root period aphid and lotus root maggot occurring for a long time, the dimethoate emulsion of 1000 times of the spray dilutions of eliminating aphis a time is controlled the lotus root maggot and can every mu be executed the control of double centner albarium.

The present invention compared with prior art, its difference is exactly the standard-required that the present invention produces in strict accordance with the green non-pollution vegetables, changed the history of lotus rhizome self-sow in the past, in whole cultivation management process, implement effectively artificial control, output significantly improves, about 2000 kilograms of the general per mu yields of the hollow lotus root in lake, and non-irrigated lotus root per mu yield can reach 5000～6000 kilograms, its quality also improves greatly, through Ministry of Agriculture food quality supervision verification test center (Jinan) 17 indexs are chemically examined, all reached green food standard, and the hollow lotus root in lake only there is five indices qualified.

Embodiment

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

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

3, non-irrigated lotus root growth management: in the growth of seedling phase, in time remove pasture and water, improve photosynthesis to increase light transmission; At its assimilation organ growing period, often remove pasture and water, return lotus root, pluck floating leaf, windproof, return lotus root and carry out in the afternoon; Becoming lotus root period, keep dark 10～15 centimetres of lotus root pool inner water, prevention aphid and lotus root maggot, if when aphid and lotus root maggot occurring for a long time, the dimethoate emulsion of 1000 times of the spray dilutions of eliminating aphis a time is controlled the lotus root maggot and can every mu be executed the control of double centner albarium;

4, after adopting lotus root, enter the winter management in lotus root pond, evenly replenish fertilizer, pour water to the lotus root pool inner water dark 25～30 centimetres then.Can reach more than 50 years the service life in a lotus root pond.

For increasing economic efficiency, but the lotus root fish raise together with, purify water.
