Abstract

The invention provides a lemon grass seedling technique which comprises the following steps of selection of a seedling land, preparation of bed soil, treatment of seeds, seedling management and outplanting. By means of the lemon grass seedling technique, nitrogen-phosphorus-potassium mixed fertilizer is used as base fertilizer, the weight ratio of nitrogen phosphorus and potassium in the nitrogen-phosphorus-potassium mixed fertilizer is adjusted, nutrient content needed by growth and development of seedlings is balanced, growth of the seedlings is promoted, the growth vigor is good, and a foundation is laid for production increasing of lemon grass.

Description

A kind of lemon-grass seedling growing process

Technical field

The present invention relates to technical field of agricultural seedling-raising, be specifically related to a kind of lemon-grass seedling growing process.

Background technology

Lemon-grass (Cymbopogon citratus.), also known as lemon grass, lemon grass (Cymbopogon citratus), is the dulcet plant of a kind of tool.Perennial herb, complete stool has the fragrance of lemon, plant height 100-200 centimetre, grow thickly, by white cured powder, what underground, stem short Tibetan, joint colyliform, leaf sheath embraces stem without hair, and wire leaf goes out near root director, the long 60-150 centimetre of leaf, wide about about 1.5 centimeters, blade clusters, and the two sides back of the body is coarse.

Lemon-grass adaptability is comparatively strong, selects also comparatively loose to soil, and the knob growth abundant at rainfall is very fast, grows vigorous and without damage by disease and insect, the weather of Fangcheng District and soil, be applicable to the plantation of lemon-grass very much.Due to lemon-grass easily cultivate, vegetative period is short, less investment, produces effects fast, once plantation can be benefited for many years, is the feasible way that a plantation is got rich.

Summary of the invention

The invention provides a kind of lemon-grass seedling growing process, it, by optimizing the seedling growing process of lemon-grass, strengthens the growing way of seedling, and then significantly improves the output of lemon-grass.

The technical solution adopted in the present invention is: a kind of lemon-grass seedling growing process, described seedling growing process adopts following steps to realize: step 1: nursery is selected: selective temperature between 15 to 20 DEG C, many wet, soil is deep, fertile, well-drained sandy soil ground is as nursery; Step 2: bed soil preparation: before sowing, sandy soil are ploughed deeply, the mixing fertilizer that every mu applies nitrogen, phosphorus, potassium are laid equal stress on, bedding of then raking, more every plot of land earth is watered permeable; Step 3: seed treatment: knocked open gently by kind of core before sowing, takes out kind of a benevolence, soaks 2 days, pull out and drain with cold water at 15 DEG C; Step 4: sowing: plant benevolence and be sprinkling upon on bed soil equably, covers one deck earth on kind of benevolence, and the thickness of the earth covered is kind of the 2-3 of benevolence diameter times; Step 5: manage between seedling: utilize sprayer to the moisturizing of bed soil water spray, once a day, keep soil moisture content; The germination temperature of planting benevolence is suitable at 15-30 DEG C, if do not reached, and can at bed soil surface coverage one deck preservative film; To intertill in time after coming up, loosen the soil, weeding, a thinning to be carried out when seedling grows 3-4 sheet true leaf; Step 6: go out garden: if soil drought before going out garden, first water, lifting again after soil is slightly dry, both easy lifting, protect again root system complete; Lifting can adopt offshoot or full clump pick on the spot to get offshoot, classification immediately after lifting, and bundling classification, root dips in mud.

Further, in step 2, in mixing fertilizer, the weight ratio of nitrogen, phosphorus, potassium is 0.8:1:0.5-0.8.

The invention has the beneficial effects as follows: emergence rate of the present invention is high, utilize nitrogen-phosphorus-potassium compound fertilizer to make base manure, and regulate the weight ratio of N P and K three in nitrogen-phosphorus-potassium compound fertilizer, balanced seedling growth grow required for nutrient component, facilitate seedling growth, grow fine, for lemon-grass volume increase lays the first stone.

Embodiment

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

Embodiment 1:

The seedling growing process of lemon-grass of the present invention, described seedling growing process adopts following steps to realize:

Step 1: nursery is selected: selective temperature between 15 to 20 DEG C, many wet, soil is deep, fertile, well-drained sandy soil ground is as nursery;

Step 2: bed soil preparation: before sowing, sandy soil are ploughed deeply, the mixing that every mu applies nitrogen, phosphorus, potassium are laid equal stress on is fertile, and the weight ratio mixing nitrogen, phosphorus, potassium in fertilizer is 0.8:1:0.5, bedding of then raking, then waters permeable by every plot of land earth;

Step 3: seed treatment: knocked open gently by kind of core before sowing, takes out kind of a benevolence, soaks 2 days, pull out and drain with cold water at 15 DEG C;

Step 4: sowing: plant benevolence and be sprinkling upon on bed soil equably, cover one deck earth on kind of benevolence, the thickness of the earth covered is 2 times of kind of benevolence diameter;

Step 5: manage between seedling: utilize sprayer to the moisturizing of bed soil water spray, once a day, keep soil moisture content; The germination temperature of planting benevolence is suitable at 15-30 DEG C, if do not reached, and can at bed soil surface coverage one deck preservative film; To intertill in time after coming up, loosen the soil, weeding, a thinning to be carried out when seedling grows 3-4 sheet true leaf;

Step 6: go out garden: if soil drought before going out garden, first water, lifting again after soil is slightly dry, both easy lifting, protect again root system complete; Lifting can adopt offshoot or full clump pick on the spot to get offshoot, classification immediately after lifting, and bundling classification, root dips in mud.

Adopt aforesaid way to make the breeding experiment of lemon-grass, find that this seedling-cultivating method makes the survival rate of lemon-grass to more than 98%, and seedling increases production 20,000 plants/acre.

Embodiment 2:

Step 2: bed soil preparation: before sowing, sandy soil are ploughed deeply, the mixing that every mu applies nitrogen, phosphorus, potassium are laid equal stress on is fertile, and the weight ratio mixing nitrogen, phosphorus, potassium in fertilizer is 0.8:1:0.8, bedding of then raking, then waters permeable by every plot of land earth;

Step 4: sowing: plant benevolence and be sprinkling upon on bed soil equably, cover one deck earth on kind of benevolence, the thickness of the earth covered is 3 times of kind of benevolence diameter;

Adopt aforesaid way to make the breeding experiment of lemon-grass, find that this seedling-cultivating method makes the survival rate of lemon-grass to more than 96%, and seedling increases production 1.8 ten thousand plants/acre.

In sum, adopt seedling growing process of the present invention, emergence rate is high, nitrogen-phosphorus-potassium compound fertilizer is utilized to make base manure, and regulate the weight ratio of N P and K three in nitrogen-phosphorus-potassium compound fertilizer, balanced seedling growth grow required for nutrient component, facilitate seedling growth, grow fine, for lemon-grass volume increase lays the first stone.
