First, the sunshine rose heart-picking method:
Secondary heart-picking method: for winter to be ultra-short shoots (one bud or two buds (bottom bud + 1 bud)) pruning, 20-25 days after budding, 6 leaves, that is, when 3-4 leaves can be seen on the tidbits. For two bunches of flowers, one leaf is left on top of the top of the bunch of flowers; one bunch of flowers, two leaves are left on the flowers, and the hearts are slightly plucked (that is, the six leaves and one heart period, from bottom to top, the sixth piece is about one-third the size of the normal leaves, and the whole branch leaves 6 leaves to pluck the hearts). When the flowers are seen, all the branches of the whole garden leave 6 leaves upwards in the mouth of the last heart picking, and the heart is slightly picked. Then leave 6 leaves to pick the hearts.
One-time heart-picking method: for winter to be pruned in the middle and long shoots, when the flowers are seen, leave 5-8 leaves on the flowers.
Post-hearted secondary management:
One sub-shoot is left under the flower, and 1-3 leaves are plucked after the top, and after the fruit is soft, these two sub-shoots can also be removed without blocking the sun.
The purpose is: to retain the leaf function at the same time, to prevent sunburn. The top parasings are left well, and the rest are erased. The time interval between the toppings and the erasure of the parasitoids is one week to prevent the explosion of winter buds.
(Two bud pruning)
(One bud pruning, also called diaphragm shear)
(One bud pruning, management in place, all flowers)
In addition, let's say:
1. "6+6+6" topping is an important supporting measure for the two buds to cut flowers in winter.
2, wangzhi left two strings, moderate branches left a bunch, weak branches do not leave tidbits, if you want to leave a bunch of fruits, you can leave the string that you don't want late, in order to contain the growth, and there is no formula for which to leave, in short, the final purpose is to make the whole garden's tidbits fertility period as synchronized as possible.
3, grape hearthing, pruning there is no fixed formula, a person a method, suitable for their own good.
Second, thin flowers and fruits
Sunshine Rose does not recommend gibberellosis pulling flowers, which can be elongated by picking hearts and strengthening fertilizer water supply:
6 leaves were plucked, and then the seaweed humic acid balance solution (seaweed extract≥200g/L, mineral-derived humic acid ≥30g/L, nitrogen, phosphorus and potassium ≥200g/L) 800-1000 times sprayed, mu balance fertilizer (22-10-20+TE) 5 kg.
See 10 days before flowering, that is, 35 days after germination, the flowers begin to flower after the basic separation of the tidbits, and can be completed at the latest before the first flowering, the earlier the completion, the better the fruit set and young fruit development. Only 12 or 20 branches and 80 buds are retained per tassel, and all the excess buds are removed.
After 7 days of fruit preservation, when the fruit grain is large, the fruit is thinned, and there are two general standards:
The first is that a layer of flowers, twenty small branches (divided into 4 groups, a group of 5 branches), about 65-70 grains, the top five small branches leave 5 grains, the next three groups of small branches in turn leave 4/3/2 grains; the second is, 13-15 small branches, belonging to the fine fruit, about 50-55 grains.
Third, the sun rose regulator reference use method:
1, see the flower heartaching at the same time 200ppm medical streptomycin + anti-gray mold drug + anti-green blind bug medicine, can be dipped in spikes, can also be sprayed in the whole plant, focusing on the fruit spikes, which is a key step of denuclearization.
2. After the whole garden is full of flowers, complete the fruit preservation within 48 hours, 10-25ppm gibberellomic acid + 2ppm chloropyrurea + 200ppm streptomycin, dipping flowers, seedless + fruit preservation. The temperature is higher than 30 degrees Gibbernic acid concentration should not exceed 20, 25 degrees Celsius Gibberellow can be 25 ppm.
3. 12-14 days after fruit preservation, 25ppm gibberellomycoic acid + 2-5ppm chloropyramide + 5000 times Pomering, dipped in spikes.
Note: Fertilizer water supply (5 kg per mu of balanced fertilizer (22-10-20+TE)) is carried out two or three days after fruit set treatment and immediately after expansion treatment to ensure the quality of the expanded fruit.
