Description

A kind of Rhizoma Dioscoreae field production fertilizing method

Technical field

One Rhizoma Dioscoreae field production fertilizing method of the present invention, belongs to crop-planting field, and special Rhizoma Dioscoreae field production is applied fertilizer.

Background technology

Rhizoma Dioscoreae also known as Rhizoma Dioscoreae, soil potato, mountain Rhizoma Dioscoreae, RHIIZOMA DIOSCOREAE fr0m Henan of China, Rhizomadioscoreae, white Rhizoma Dioscoreae, is " China book on Chinese herbal medicine " medical herbs of recording, medicine It is Dioscoreaceae plant Rhizoma Dioscoreae dry rhizome with source.It is strong that Rhizoma Dioscoreae has nourishing, aid digestion, holds back sweating due to debility, and effect of antidiarrheal cures mainly Insufficiency of the spleen diarrhoea, cough due to deficiency of the lung, diabetes are quenched one's thirst, oliguria frequency, seminal emission, women's leukorrhagia and dyspeptic chronic enteritis.Rhizoma Dioscoreae Optimum is taken with Ganoderma collocation, has the effect preventing and treating diabetes, and Rhizoma Dioscoreae is the most rising on grocery trade and processing industry. Rhizoma Dioscoreae has special requirement in field production fertilising.

Summary of the invention

The technical problem to be solved is to provide a kind of Rhizoma Dioscoreae field production fertilizing method, solves Rhizoma Dioscoreae land for growing field crops Cultivation problem of fertilization and high-yield and high-efficiency.

The cultural method that the present invention uses, comprises the steps: site preparation and fertilization；Topdress.

Further, the technical essential of site preparation and fertilization is as follows: select soil layer deep, loose, and the sandy loam of non-continuous cropping in 3 years Soil, ploughs deeply 35 centimetres in winter in the first year, makees high furrow after the beginning of spring, and base manure is shallow imposes on topsoil, takes kind of a block of first planting, digs subsequently The method of fertilising, selects argol, plant ash to mix thoroughly with soil, and muck first becomes thoroughly decomposed, and executes 30000～60000 kg/ha, executes carbamide 300～375 kg/ha, calcium superphosphate 225 kg/ha, potassium sulfate 375～525 kg/ha.

Further, the technical essential topdressed is as follows: executes a loose stool during neat Seedling and urinates 15000 kg/ha, later every Within 20～30 days, execute 1 time, fertile 15000～22500 kg/ha of the fecaluria that each ditch spread is become thoroughly decomposed, after plant buddings, answer heavy dressing denseer Night soil and cake fertilizer mixed liquor 30000～60000 kg/ha, see plant growing way, supplementary fertilizer 1 time when gathering in the crops first 40 days.

The invention has the beneficial effects as follows: method is simple, yield is high, and economic benefit is obvious.

Detailed description of the invention

Below in conjunction with example to the present invention principle and feature be described, example be served only for explain the present invention, It is not intended to limit the scope of the present invention.

Site preparation and fertilization: Rhizoma Dioscoreae absorption root buries shallower and tuber buries relatively deep, and therefore, certain selection soil layer is deep, loose, And the sandy loam of non-continuous cropping or loam in 3 years, plough deeply more than 35 centimetres in winter in the first year, make high furrow after the beginning of spring or plant in ditch ridge. Owing to the main absorption Root Distribution of Rhizoma Dioscoreae is in upper layer of soil, therefore base manure is shallow imposes on topsoil, takes kind of a block of first planting, subsequently The method of digging fertilizers into fields.Base manure preferably selects argol, plant ash or farmyard manure to mix thoroughly with soil.Muck should first become thoroughly decomposed, and typically executes 30000 ～60000 kg/ha, execute carbamide 300～375 kg/ha, calcium superphosphate 225 kg/ha, potassium sulfate 375～525 Kg/ha.In the area shorter without the dew phase, in order to extend its growing stage, improve yield and quality, nursery can be taked to move The method planted, utilizes protection facility to carry out seedbed nursery, and then field planting in good time is to big Tanaka.Topdressing: early stage, Rhizoma Dioscoreae is mainly with ground Upper stem and leaf is grown to main, and subterraneous stem increases relatively slow, and fertilizer requirement is the most less.Therefore from sowing or transplanting until tiller all can be executed in a large number The muck become thoroughly decomposed, typically executes a loose stool and urinates about 15000 kg/ha when neat Seedling or after transplanting survival.Later every 20 ～within 30 days, execute 1 time, fertile 15000～22500 kg/ha of the fecaluria that each ditch spread is become thoroughly decomposed or NPK 225～300,000 Gram/ha.After plant buddings, underground tuber, while rapidly elongation, also progresses into and expands increasing thick weightening finish period, need fertile acute Increase, now answer the denseer night soil of heavy dressing and cake fertilizer mixed liquor 30000～60000 kg/ha or three elements compound fertilizer 600～ 750 kg/ha.This topdresses is the most key fertilizer maximum on Tuber yields impact.Later when the climing shelfful of stem, as Being found to have de-fertile phenomenon, can chase after disposable fertilizer again, amount ratio is previous secondary few.Last then see plant length when first 40 days of results Gesture, supplementary fertilizer 1 time, to improve Tuber yields and quality.After the Frost's Descent, stem and leaf is withered and yellow on the ground, should gather in time.

Claims
