How much does wild puncture vine cost per jin? Yield per mu and high-yield cultivation techniques

Puncture vine, also known as white puncture vine and quren, among other names. It is distributed throughout the country. It grows in sandy land, wasteland, hillsides, near residential areas and other places. When fresh and green it can be used as feed. The fruit, used as medicine, can calm the liver and improve eyesight, dispel wind and promote blood circulation. So how much does wild puncture vine cost per jin? How many jin can one mu of land yield?

As for the price of wild puncture vine, there is a certain amount of supply available on the market. At present, the market price for de-thorned puncture vine is around 23 yuan, and the price for thorned goods is around 15 yuan.

How many jin can one mu of puncture vine yield

Seed propagation. In August to September, when the seeds mature, select large, plump, full greenish-white fruits and dry them in the sun for later use. Before sowing, spread the seeds on a stone roller and crush them so that the fruit segments separate, winnow away the fruit thorns and shell debris, and keep the pure seeds for sowing. The seeds can also be passed twice through a rice milling machine, and the seeds screened out. From late March to early April in spring, water the seedbed surface thoroughly, scatter the seeds, and cover them tightly. For dibbling, dig holes at a row spacing of 50cm and a plant spacing of 30-40cm, drop 4-5 seeds into each hole, cover with soil and water, with a sowing rate of 1-2kg per 667m2. The seeds can also be pregerminated and placed in a fluid suspension gel prepared with a water-retaining agent as the medium, then sown with a fluid seeder, which is more favorable for germination. The optimal planting density for puncture vine is about 10cm plant spacing under 60cm ridge cultivation, and the optimal harvest period is late August.

Land selection and land preparation

Puncture vine has wide adaptability and is not strict about soil requirements, but it prefers loose-textured, fertile sandy loam.

Field management

1. Thinning: When the seedlings are 4-7cm tall, pull out weak and overly dense seedlings; when the seedlings are about 10cm tall. For broadcast sowing, keep seedlings at a plant spacing of 30-40cm; for dibbling, keep 2-3 strong seedlings per hole. If missing plants or missing holes are found, they should be transplanting with soil to fill them in.

2. Intertillage and weeding: When weeds appear after emergence, carry out intertillage and weeding in time. When hoeing, it should be shallow at the seedling stage, preferably 1-2cm.

3. Topdressing: On the basis of applying sufficient base fertilizer, appropriate topdressing should be carried out according to soil fertility conditions, generally twice.

4. Pinching the top: After mid-August, in order to allow the seeds to mature in a concentrated manner, the growing points of each branch can be pinched off, which can cause more short branches to grow on the vines, bear more fruit, and mature earlier.

Pest and disease control

1. Diseases: Wild puncture vine has very mild diseases. Common diseases of cultivated puncture vine include white rust, black spot, powdery mildew and rust, as well as seedling damping-off.

2. Pests: Common pests include crickets, bean aphids, red spiders, and so on.
