Cost analysis: usually you need to use 20-25kg of mother root for one mu, which costs about 300-500 RMB in total; it costs about 3,000 RMB to build a stand, and the annual fertilizer cost is about 500-600 RMB/mu. Profit: The mu output of piper betel is 200-220kg, the market price is 16-20 RMB/kg, plus the piper betel kernel, the final profit can reach 4000-5000 RMB/mu.

I. Costs and benefits of piperidium guajava planting

(2) In the first year, it costs about 3,000 yuan to build a stand, and the cost of fertilizer is about 500-600 yuan per mu.

(3) The total cost for the first year adds up to about $3800-$4100 or so.

2. Profit

Second, the piper betel planting method

1, land preparation

(1) land requirements: planting of sandy loam plots require sunny leeward, the soil layer is deep, the soil is loose and fertile, with good drainage, ph in 6.7-7.2 between.

(2) land treatment: with deep plowing and deep turning of the land (deep turning 25cm), each mu of land in the autumn after the application of 5000kg rotted farmyard manure as a base fertilizer. Leveling to make beds, bed width 120cm.

2, sowing

(1) seed treatment: choose 2-3 years old female plant tubers (required uniform thickness, truncation surface white fresh, no pests and diseases), then cut it into 5-7cm small section, and dip the incision in the grass ash, drying ready for sowing.

(2) Sowing time: in March - mid-April sowing.

(3) Sowing method: digging holes for sowing, rows and plants 120?100cm apart, hole depth 10-12cm. put a section of tuber flat in each hole, then cover a layer of 3-5cm thick soil on top, water after covering.

3, management

(1) In the sowing before the emergence of seedlings, each acre of land using 70-100ml of ethofumesate diluted in water spray.

(2) When the stem grows to more than 30cm, set up a stent to draw the vine on the shelf. The bracket a *** set up 3 rows, height 1.5m or so, row spacing 2.4-2.7m, plant spacing 2-2.4m.

(3) lead vine on the shelf, pay attention to pruning fork, cut off the weak vine as well as futile vine, to ensure that nutrients centralized delivery.

(4) From the second year onwards, fertilizers are applied twice a year, at about 34cm seedling height, and in mid-June (during flowering). Each time, 500-1000kg of well-decomposed human feces or 50kg of soybean cake fertilizer + 10-15kg of urea + 15kg of calcium superphosphate per mu was applied.

(5) During flowering, pay attention to artificial pollination.
