Summary of the invention

In order to make full use of fertilizer efficiency, reducing production cost, ensureing that excavating of konjaku is convenient and swift, the present invention proposes a kind of konjaku implantation methods of pad film ridging of ditching, and possesses the advantage of fertilizer conservation, insulation, disease-resistant, high yield.

For this reason, technical scheme of the present invention is: a kind of konjaku implantation methods of pad film ridging of ditching, and concrete steps are:

(1). seed selection: select the konjaku of 50-300 gram to do kind of a taro;

(2). trench digging: by the specification trench digging that 0.8-1.2 rice is wide, dark 20-30 centimetre, bottom of trench paving black Perforated plastic film;

(3). sowing and fertilising: black Perforated plastic film upper berth farmyard manure, farmyard manure covers the soil of 2-5 cm thick; Then on soil layer, a kind taro is put by certain spacing in the rows and line-spacing, then earthing ridging, ridge height 20-40 centimetre; Face, ridge upper cover grass 2-5 centimetre; Mu farmyard manure 1000-1500 jin.

Beneficial effect: in the present invention, by bottom of trench paving black Perforated plastic film, daytime absorbs surface temperature, has the function heated, and the glassware for drinking water of black Perforated plastic film surface condensation has the function of soil moisture conservation, strengthens konjaku root system respiration and has disease-resistant function; The black Perforated plastic film of bottom of trench just serves the release promoting farmyard manure fertility, avoids fertilizer efficiency to run off, and strengthens the utilization of fertility; Earthing isolation between konjaku and base manure, and konjaku root system is longer, absorption ability of nutrient is strong; Ditch heelpiece black Perforated plastic film the planting patterns of Ridged plant, flat, smooth at the bottom of konjaku, the coefficient of expansion is large, the depth is consistent, spacing in the rows is even, excavates convenient and swift; Summary, the present invention can make full use of fertilizer efficiency, reduces production cost, ensures that excavating of konjaku is convenient and swift, possesses the advantage of fertilizer conservation, insulation, disease-resistant, high yield; A labour can excavate 500-600 jin in one day, can save for every mu and excavate cost 400-500 unit.

Embodiment

embodiment 1

Ditch and pad a konjaku implantation methods for film ridging, concrete steps are:

(1). seed selection: select the konjaku of 150-200 gram to do kind of a taro, select that eye is full, bud nest is shallow, outward appearance just, epidermis is smooth, without damaged, without scab, konjaku that nothing is rotten;

(2). select the area of height above sea level 600 to 1400 meters, soil layer is deep, be rich in organic sandy loam; Plough deeply arable land before entering the winter, the degree of depth reaches more than 30 centimetres, and object is the worm's ovum of surviving the winter of freezing to death, loose soil property; Sowing is started by 15 degrees Celsius when ground temperature is stable, by the specification trench digging that 1.1-1.2 rice is wide, dark 20-30 centimetre, bottom of trench paving black Perforated plastic film;
