What kind of vine is more likely to survive and produce more fruit?

Sapphire grapes.

Sapphire fertilization management program.

1. Flowering period.

From the beginning of flowering to flowering, about 5-14 days. The suitable temperature for flowering is 25 32, if the temperature is lower than 15, it will not be able to bloom and fertilize normally. Therefore, it is necessary to apply fulvic acid-containing fertilizers before and after flowering to promote fertilization and fruit set.

In addition, it is necessary to tie vines and topping in time, remove secondary shoots, improve ventilation and light transmission conditions, and manually pollinate poor flower spikes.

1) Fertilize and water.

5 days before the grapes bloom, spray Ribery Yanwo chelated boron fertilizer to promote flowering and fruit preservation fertilizer, and control the crazy growth of the strips to improve the fruit setting rate. Fertilizer and moisture should also be properly controlled**.

2) Pick the inflorescence.

Before flowering, remove the inflorescences on the weak branches that grow relatively weakly, and leave a panicle for the mediocre branches.

3) Trivia shaping: Remove the inflorescence shoulder, and remove the 1 5 at the tip of the inflorescence 3-5 days before flowering.

4) Remove tendrils and tie branches and vines The new shoots should be pinched off as soon as possible, and the new shoots should be tied and fixed in time to avoid wind damage.

5) Disease and insect prevention Spray Bordeaux liquid or carbendazim with chlorantraniliprole before flowering to avoid diseases such as gray mold and black pox and insect pests such as spotted wax cicadas.

2. Berry growth period The growth time of berries is probably from the ovary to the beginning of the softening and coloring of the berries. During this period, the nutrient consumption is more, and nitrogen, potassium, calcium, boron, manganese and zinc fertilizers should be increased in time, 2 5 kg of water and fertilizer should be applied per mu, and foliar fertilizer should be sprayed 2 3 times together, which can promote fruit expansion, coloring, sweetening, and weight gain.

3. Berry ripening period from the beginning of the fruit to become soft and colored to complete ripening, about 20 to 30 days. At this time, the berry volume no longer increases significantly. It is mainly due to the accumulation and transformation of nutrient substances, the color of the fruit becomes softer, the acidity is reduced, and the sugar content is increased.

Tree grape is a large tree fruit tree that grows all year round, and is named tree grape because its fruit resembles a grape. It is a newly discovered special species hidden in the primeval forest, which can bloom and bear fruit four times a year, and is a national key protected species.

Grape roots are thriving, regenerative and absorbent, so grapes are drought-resistant, barren, salt-alkaline, and not afraid of hurting roots by farming. The plant is vine and cannot stand upright, so it needs to be supported by a scaffold. The branches are called branches, which grow rapidly, have long internodes, and grow upward by tendrils, and the annual growth can reach more than 1 meter to 10 meters.

1. Strengthen the management of the garden in spring, remove dead branches and fallen leaves, turn the soil deeply, fade the old skin, and spray the whole garden with stone sulfur mixture and other drugs to kill bacteria, fungi, tree trunks and overwintering insect eggs in the soil. The application of basal fertilizer can increase the nutrient demand of fruit trees and improve the disease resistance of fruit trees.

2. After the new leaves are exhibited and before the fruit ears bloom, do a good job of tying vines in time, spray carbendazim or chlorothalonil and other drugs to the fruit trees to stop the sterilization of leaves and fruit ears, and prevent the breeding and spread of bacteria. Spray foliar fertilizer, supplement various trace elements required by fruit trees, increase nutrition, improve the disease resistance of fruit ears and leaves, prevent the onset of pests and diseases, and improve yield.

3. Reasonably stop thinning and wiping buds, erase the secondary teeth of a bud eye (stop after germination in ordinary spring), thin out weak branches, diseased branches, dense branches, and branches with unreasonable growth, so that the proportion of fruit tree branches is evenly dispersed, improve the high-quality conditions of fruit tree ventilation and light transmission, enhance the photosynthesis of leaves, and improve disease resistance. Reasonable and effective stop the sterilization of fruit trees. It can effectively prevent bacteria from breeding and breeding diseases.

4. Strengthen the management of the garden in the rainy season, and do a good job in the drainage measures of fruit trees. In the rainy season, it is necessary to strengthen the spraying of fungicidal drugs for fruit trees, reduce the onset of pests and diseases, remove diseased fruits, diseased ears and leaves, and stop drugs reasonably and effectively to avoid the spread of diseases. Stop topping and control the work in time to make the fruit trees have a good ventilation environment and reduce pests and diseases in the high temperature season.

Pay more attention to the growth of fruit trees and fruit ears, and prevent diseases as soon as possible.

5. After harvesting in autumn, stop the cleaning work and spray drugs to stop sterilization and insecticide in the garden. Prevent and control bacteria and insects and hunger in the garden to provide strong conditions for the growth of fruit trees in the coming year. Reduce the onset of pests and diseases.

When topdressing grapevines, stop irrigation and grass mulching before flowering to promote a large number of flower bud differentiation, top dressing and watering during the fruiting period to provide sufficient nutrition, and stop the control work according to the law of pest and disease disease.

Be sure to prune the branches and leaves frequently, but also to ensure soil fertility, to irrigate in time, add a feast to a strong water and fertilizer management, and then take new shoots topping or treatment of secondary shoots and other behaviors, in the spring you can choose to bag and then spray, to be suitable for the time to replenish the water, the temperature should be controlled at about 25 degrees, every 10 days or 15 days to supplement fertilizer.

From November to December every year, it is necessary to cut some unhealthy branches. In mid-March, the osmosis requires deep irrigation to ensure that the grapes are well watered.

To choose the right variety for planting, pay attention to light, pay attention to watering, pay attention to the use of fertilizers, and be sure to pay attention to pruning.

Grape seeds are planted on the ground to produce vines, preferably in autumn or spring.

The vines that grow from grape seeds will bear fruit, but the grapes will not produce benign grapes of the same variety, the grape traits may change, the taste will not be as delicious as before, and the grapes produced are mostly cultivated by hybrids rather than grown naturally.

Viticulture is mostly propagated by cuttings or grafting, rather than seeds. Due to the slow growth of grape seeds, it takes a long time to flower and bear fruit, even up to ten years, while cuttings or grafting only take three years to bear fruit.

It is when the fruit is too ripe that this phenomenon occurs, and the fruit should be plucked, and the fruit is very sweet.

It may be that the grapes are frozen because they are not well insulated, so they will keep cracking.

Uncoordinated growth of the pericarp: The use of plant growth regulators has become quite common, but when used in large quantities, it can inhibit the growth of the pericarp, causing the pulp to break through the pericarp.
