Plant technology

 

1. planting and row spacing:
4 m spacing, spacing 2 meters per subdivision 120, three students thinning 60, five students thinning 30, as the case after thinning.
2. The establishment of tree pruning:
Seedlings were grown to 20 to 30 centimeters under the scaffolding at the topping, the end of the stay two points buds, buds on the scaffolding when the points, using straw after soaking to soften lure Chengding shaped branches, branches grow to about 1 meter topping trunk promoting fluid bud initiation, bud every five was left a shoot, bud intermediate 4 was removed, the first year can constitute the main branch, sub-main branch structure, the first two years to enter the results of tree vigor.
3. Promote Sprout:
Taiwan is located in a subtropical climate, the winter temperature insufficient amount, causing germination rate and irregular budding phenomenon, if germination has inconsistencies, the new growth potential is slightly uneven, the result of fertility regulation difficulties affecting flowering, fruit set, fruit growth and quality and so on . After the winter pruning can be sprayed 49% solution of cyanide Mansour 50 times or 20 times the calcium cyanide amino immersion liquid coating shoots and buds, promote and improve the germination rate germination neat effect.
4. Promote the development spikes:
To sprout new shoots after 4 leaves tree if insufficient nutrient storage, suffered long Hanyu or cold, spikes shoot rudimentary or spikes on the end of atrophy, the impact spike and yield, irrigation facilities before winter pruning microbial fertilizer to promote early root growth, to drive nutrient transport tree water can reduce the rate of contraction spikes. And in the early shoot growth Spraying cytokinin, auxin and Bo hormone mixture.
5. flowering shoots before adjusting fertility:
Nutritional influence over the event before flowering flower hypoplasia, to improve their physical defects, observed in 4 to 6 leaf shoots top bending, bending the stronger the greater the degree of regenerative force, affecting the degree of development of flower more serious, should be adjusted begins work for spraying a high concentration of phosphorus, potassium, calcium, boric acid and sweet and sour liquid, etc., can be controlled growth of shoots before flowering, to improve the fruit set.
6. sparse flowers, fruit thinning and bagging:
Spike shape of large red grapes honey, prune before flowering spikes reduce the number of flower stalk, so that all the small flowers bloom at the same time, the fruit and seeds evenly distributed fruit thinning can reduce working hours, the number of fruit per panicle after thinning 30 to 40, 10 grams each and every ear can get 300 to 400 grams, is too large, colored ear of late, easy to soften the fruit, so the fruit thinning is to create high-quality production of the most important jobs.
Spike sparse amount of time to adjust the results, insufficient number of weak branches of the first leaf ear cut off, leaving two shoots grow strong spike, then the number of control units and other area two kinds of methods to control the results of the amount at the time of bagging, bagging several per subdivision control in about 4500, with production target of 1300 to 1800 kg.
Sixth, the late fruit growth Fertility Management:
40 to 50 days after flowering, the fruit soluble solid start 急遽 rise, if excessive shoot growth and fruit nutrient competition is not conducive to fruit sugar accumulation and affect coloration, usually at this time should be controlled to the results of branch growth, its length 100 cm stop the heart, to 70 days after full bloom branch length from 100 to 150 centimeters, stop the heart rate more than 80%, 65% mature branches, leaves 4 to 5, leaf nitrogen content of 1.8 to 2.4%, etc. for honey red grapes Coloring branch of birth benchmark results, but close planting garden tree burden less, or nitrogenous fertilizer excess branches long, blade overlap insufficient sunshine, low photosynthetic capacity of leaf premature aging, resulting in a color, small fruit, low sugar content, flesh softening problems should shoot growth and root growth rings and other improvement and management cooperation, in order to stabilize production and enhance quality.
Seven harvest:
Summer fruit:
Ground red grapes summer fruit harvest honey should not be dragged on mid-July, this time due to high day and night temperatures, adequate moisture, quality susceptible to harvest 5 to June more appropriate, its time to push forward the prune Article 150 day, that is 12 to January implementing the operations and shall prevent chilling injury.
Winter Fruit:
After the summer fruit harvest is completed, the park is fully disinfected, Shi Caesar dressing to complement the tree nutrient, in mid-July - the end of August pruning job, 120 days to harvest, 11 to January harvest.
