Description

A kind of close kind of Precision Seeding cultivation technique of Herba Andrographitis

Technical field

The invention belongs to technical field of crop cultivation, and in particular to a kind of close kind of Precision Seeding cultivation technique of Herba Andrographitis.

Background technique

Close kind of Precision Seeding cultivation technique of Herba Andrographitis is on the basis of essence amount, semi-accuracy seeding technology, to expand sown scope, line increment Away from, promote even broadcast and change the agricultural machinery that intensive drilling is close kind of Precision Seeding and the high-yield culture technique that agronomy combines for core.

Summary of the invention

The technical problem to be solved by the present invention is to be directed to the deficiency of existing Herba Andrographitis cultivation technique, a kind of Herba Andrographitis is provided Close kind of Precision Seeding cultivation technique, small investment, high efficiency, operation is simple.

To achieve the goals above, the present invention is achieved by the following scheme: a kind of close kind of Precision Seeding cultivation of Herba Andrographitis Training technology, including following specific steps:

A, the selection of kind: selecting and remain high quality seed, when 9-10 month fruit is in common brown, adopts in batches before dew is not dry in the morning It plucks, is placed on frescade, can be 7 days in fruit pod self heating, it is covered during sunning with cover, the capsule seed that splits is prevented to be scattered, Tomato seeds are tiny, dry granular weight 0.93-1.52g;The high middle fringe type kind of rate of tillering panicle, per acre Basic Seedling 12~150,000；It broadcasts Before to select the high seed coat agent of quality to carry out seed pelleting；Such as No. 4, Jinmai 49 are educated in Gansu Province mirror 386, Gansu Province；

B, culture fertility: adhering to fertilization compositions based on earth measurement, payes attention to straw-returning, increases chemical nitrogen fertilizer, culture fertility；Seed is used and is rubbed Erasure reason, is dressed seed with sand, and with cold water or water seed soaking 8-12 hour, but no more than 12 hours, otherwise random kind easy, seed dries in the air It shines 3-4 days, then is placed on vernalization in 30 DEG C of incubators, then sow, often to keep seedbed wet before emergence, relative humidity is protected in furrow Holding 70%-80% is advisable, and after seedling all sprouts, should control soil moisture, to prevent samping off generation；Second year, Herba Andrographitis period of seedling establishment is again Impose 50% nitrogenous fertilizer；Chemical fertilizer will be applied deeply, prevent earth's surface and spread fertilizer over the fields；

C, adhere to that deep ploughing subsoiling, cultivated rake is mating, payes attention to prevention and treatment subterranean pest-insect: carefully rake of deep ploughing makes vola moisture in the soil；23~25 lis of tilling depth Rice, breaks plough sole, does not balk, and ploughs rake thoroughly and thoroughly, increases soil water storage soil moisture conservation；Deep ploughing will combine closely with thin rake, without bright Dark clod reaches Panasonic's reality;It puts down after ploughing, is carefully put down after bedding again, guarantee that watering uniformly, is not rushed and do not become silted up；Soil moisture content is insufficient Preceding moisture creating should be broadcast；

D, Herba Andrographitis growth period does prediction well: preventing and treating pest and disease damage in due course, especially carries out to aphid, red spider, white powder The prevention and treatment of the pest and disease damages such as disease, rust, banded sclerotial blight；

E, early spring intertills Meteorological effect, and promotion, which is turned green, imposes urea；

F, Nitrogen Top Dressing suitably moves back, and payes attention to foliage application, delays plant senesecence, it is each that the later period carries out " a spray three proofings " prevention and treatment in time Kind pest and disease damage；Delay Herba Andrographitis plant senesecence, be finally reached regulation group and individual contradiction, coordinates fringe, grain, weight triadic relation, Reach the target of Herba Andrographitis high yield with higher biological yield and economic coefficient.

Specific embodiment
