Abstract

The invention discloses a method for planting lotus roots in loam of a high-altitude region, and belongs to methods for planting lotus roots. The method for planting the lotus roots in the loam of the high-altitude region comprises the following steps of building of a lotus root field, water retention and improvement of the loam, disinfection of lotus root seeds, planting and field management. Specifically, the method for planting the lotus roots in the loam of the high-altitude region comprises the following steps that (1) the inner sides of ridges are covered with plastic film; (2) the bottom of the lotus root field is covered with clay, thoroughly-decomposed chicken manure, quick lime and a water-retaining agent, and then irrigation and uniform stirring are carried out; (3) Elian No. 8 provided with 2-4 lotus root nodes and a rear section serves as the lotus root seeds, and the lotus root seeds are disinfected through disinfectant; (4) the disinfected lotus root seeds are planted in the lotus root field with the spacing in the rows and the spacing between the rows being 1.0 m*1.0 m between April 5th and April 20th every year, and the water level is controlled to range from 1 cm to 3 cm until the lotus roots come into 2-3 new leaves; (5) the water level is gradually increased along with growth of the leaves, topdressing is carried out twice in the whole growth cycle, and the highest water level is 45 cm when the lotus roots grow into the fully developed period.

Description

The method of high altitude localities loam Lotus planting

Technical field

The present invention relates to a kind of lotus rhizome implantation methods, relate in particular to the method for a kind of high altitude localities loam Lotus planting.

Background technology

Lotus rhizome is water plants, all be unable to do without water whole vegetative period.Because lotus rhizome is to being in great demand of moisture, conventionally there is large-area plantation in many water area, the south of the River for a long time; And at water source relatively deficient high height above sea level loam area, southwest, it is a great problem that lotus rhizome is produced always.Particularly plant area in the kind of Southwest Mountainous Areas lotus rhizome less, be difficult to meet the need of market.

Summary of the invention

For the limitation of current lotus rhizome planting area, the present invention aims to provide the method for a kind of high altitude localities loam Lotus planting, utilizes the high altitude mountainous area that the inventive method can be relatively tired at water source to realize establishing in large scale lotus rhizome.

To achieve these goals, employing of the present invention and technical scheme, it comprises the construction of lotus root field, the improvement of loam water conservation, plants lotus root sterilization, plantation and field management; Concrete steps are as follows:

1) lotus root field is built, and pushes table soil to surrounding and forms lotus root field, ensures bottom width 1.5m, high 1m, top width 0.4m under ridge, plastic covering film inside ridge;

2) loam water conservation improvement, covers thick clay and the thick Chicken dung of 5cm of 5cm in bottom, lotus root field, by 100kg/667m ²consumption spreading quicklime, press 10kg/667m ²consumption spreading water-loss reducer; Then pour water to lotus root field, water, clay, quicklime, water-loss reducer, Chicken dung are stirred into a paste with rotovator;

3) plant lotus root sterilization, select rhizoma nelumbinis be 2～4 joints and with rear be for No. 8 kind of a lotus root Hubei Province lotus of joint, it is soaked 20 minutes with thimerosal; Described thimerosal is mixed by the volume ratio of 1:1 by 700 times of liquid of 50% carbendazol wettable powder and 700 times of liquid of 75% tpn wetting powder;

4) plantation, by planting in lotus root field by the seeding row spacing of 1.0m × 1.0m through disinfecting kind of lotus root, dig cave according to the length of kind of lotus root 5～20 annual April, and the dark 12cm in cave, imbeds kind of a lotus root in cave, fills and leads up with mud; Water level is controlled at 1～3cm, grows 2-3 sheet young leaves until plant lotus root;

5) field management, along with the growth of blade promotes water level gradually, whole growth cycle topdresses twice; In the time that kind of lotus root is planted 30～40 days, use become thoroughly decomposed pig manure 400kg and the fertile smart 1.2kg of multidimensional for every mu, in the time that kind of lotus root is planted 65～75 days, use become thoroughly decomposed pig manure 350kg and the fertile smart 1kg of multidimensional for every mu; In the time that lotus rhizome grows to the Sheng phase, water level is up to 45cm.

Compared with the prior art, the present invention is owing to having adopted technique scheme, therefore have variety adoption rationally, the construction of lotus root field and later maintenance low, loam improve afterwards good water-retaining property, water consumption is few, field management is simple, fertilizer is selected science, output is high, the advantage such as profitable, opened up the simple Efficient Cultivation new method of lotus rhizome in high height above sea level loam.Facts have proved, adopt the average yield per mu of the inventive method Lotus planting can reach 5200 jin, be adapted at 2200 meters of height above sea level loam area spreads completely.

Embodiment

Below in conjunction with specific embodiment, the invention will be further described:

1) lotus root field is built

Push table soil to surrounding and form lotus root field, sprinkle water, make real, ensure bottom width 1.5m, high 1m, top width 0.4m under ridge; Plastic foil is covered in to ridge inner side and uses soil compaction;

2) loam water conservation improvement

Covering thick clay and thick the becoming thoroughly decomposed of 5cm of 5cm in bottom, lotus root field has chicken manure, by 100kg/667m ²consumption spreading quicklime, press 10kg/667m ²consumption spreading water-loss reducer; Then pour water to lotus root field, water, clay, quicklime, water-loss reducer, Chicken dung are stirred into a paste with rotovator;

3) plant lotus root sterilization

Select rhizoma nelumbinis be 2～4 joints and with rear joint, have no mechanical damage, be kind of a lotus root No. 8 without the intact Hubei Province lotus of damage by disease and insect, terminal bud, this kind of lotus root immersed in thimerosal and soaked 20 minutes, pull rear covered with plastic film out, airing 10 hours; Described thimerosal is mixed by the volume ratio of 1:1 by 700 times of liquid of 50% carbendazol wettable powder and 700 times of liquid of 75% tpn wetting powder;

4) plantation

On annual April 5～20, by planting in lotus root field by the seeding row spacing of 1.0m × 1.0m through disinfecting kind of lotus root, dig cave according to the length of kind of lotus root, the dark 12cm in cave, imbeds kind of a lotus root in cave, fills and leads up with mud; Water level is controlled at 1～3cm, grows 2～3 young leaves until plant lotus root;

5) field management

Along with the growth of blade promotes water level gradually, whole growth cycle topdresses twice; In the time that kind of lotus root is planted 30～40 days, use become thoroughly decomposed pig manure 400kg and the fertile essence of multidimensional (special fertilizer for lotus root) 1.2kg for every mu, in the time that kind of lotus root is planted 65～75 days, use become thoroughly decomposed pig manure 350kg and the fertile smart 1kg of multidimensional for every mu; In the time that lotus rhizome grows to the Sheng phase, control water level and be up to 45cm.In process of growth, not only to remove weeds in lotus root pond, extract flower in time; And be also noted that and prevent damage by disease and insect.
