Optimized cultivation of early rattan table tennis grapes
The early vine ping pong grape has many advantages such as juicy meat, good taste and good fruit shape. It is the top grade of table grapes. According to the local climate and soil conditions, the following optimal cultivation techniques can be adopted in planting management techniques:
Planting method
According to the planting row spacing, we will dig a planting ditch 80 cm wide and 60 cm deep, and then apply about 3,000 kg of high-quality organic fertilizer per acre (such as chicken manure), apply a layer of 30 kg of compound fertilizer 20 cm from the surface, and mix evenly. .
The planting is generally arranged from late March to mid-April. It is better to plant the seedlings on a sunny day. Note that the rooting of the seedlings should not be too deep, and the irrigation and drainage work should be done at the same time.
Soil, fertilizer, water management
Early rattan grape fertilization should be based on high-quality organic fertilizer based on chicken manure. In addition to diligent application of thin fertilizer, early spring germination, topdressing 1 times with nitrogen fertilizer-based germination fertilizer, about 15 kg per mu, buds after germination, no more than 2000 per mu, strong branches leave 2 spikes, medium Branches leave 1 ear, individual weak branches do not leave spikes, maintain 2000 spikes per acre, and the ear weight is above 0.75 kg. The fixed buds can leave 3,000 branches per acre, the middle long branches leave 1 ear, the weak branches do not leave the ear, and 2700 ears per acre are retained. Half a month before flowering, apply 20 kg of branches to promote long-term fertilizer. After fruit setting, when the fruit is broad, the first expansion of fruit fertilizer (expanded chicken manure 150 kg + compound fertilizer); the second fruiting period 35 kg of diammonium and 15 kg of potassium. After picking in the autumn, the autumn fertilizer should be applied once again; after the leaves are removed, the orchard is disinfected with a 3 to 5 degree stone sulfur mixture.
Shaping, trimming and thinning, thinning
The trimming tree should be topped immediately when the grapes are 3% flowering, and the leaves above the flower heads begin to leave 7 leaves per branch, and the long shoots (left 2 bunches of grapes) can be left after the top. The other strips grow 4 to 5 leaves and then the top, and the secondary shoots that grow later can be completely erased; the middle shoots (left a bunch of grapes) can only stay one after the top and only grow one after the other. The secondary shoots are equal to 3 to 4 leaves and then topped, and the secondary shoots that grow later can be completely erased.
The fruit thinning time should be carried out immediately after the fruit is fruited. If the fruit is good or bad, the fruit with good fertilization or long stem will be cut off as soon as possible, leaving a uniform size of the fruit, usually about 35 to 50 grains per ear. Just fine.
