I. Quest. Skinning of grapes in late february and early march. It is not easy to heal when the grapes are cut off and has a significant impact on the water and nutrient supply. The period of application of the base fertilizer shall be followed by the fruit of the grape harvest and it is desirable that it be done sooner rather than later. It's time to quickly restore the tree. It benefits the fruits of grape winters, winters and the following year. On the other hand, the early application of the base fertilizer in the fall and the high temperature will benefit organic fertilization; then the severed roots will heal quickly and will grow rapidly. The second root growth of grapes peaked in late august to november, so the pattern of early application of fertilizers and absorption of grape root growth was consistent。
Second, the new pilot leads the way. In addition to fixing the new roof, making it reasonably distributed and ensuring adequate light, it also promotes new growth. So, if you lead a boom, you can only make the boomerang grow stronger and less favourable to later control, and vice versa. The correct course of action should be to draw the weak first in order to promote weak growth, so that the growth of the strong and the large will be suppressed and the purpose of the new growth will eventually be the same。
(iii) high-temperature dry orchards are not sterilised. High-temperature and dry weather is common after july of each year, when water is poured into orchards, if the ground is not disinfected, video footage of summer black grape cultivation techniques, hot air vapours from the high-temperature dry ground, high-temperature diseases of winter's surface — albinosis strains rise to the ear of the fruit with heat steam, making the fruit ears susceptible to disease。
Overload production. When there is a general overload of grape-mounted fruit, overload production delays the maturity of the fruit ... Lower quality and affects the value of the commodity. It also overconsumption of nutrients for the stocking of trees ... Affects the guacamole of grapes in the spring following year and reduces the amount of flowers for grapes in the second year, resulting in unstable and low-quality grape production. Production should therefore be strictly controlled. This should be done in accordance with the principle of “one in two in two” — video of the plant-planting techniques, an appropriate increase in the proportion of nutrient branches, the timely harvesting of fruit, the strengthening of post-harvest management, the maintenance of green leaves, and an increase in the stocking of tree nutrients in order to facilitate the second year of nutritional transformation for the purpose of high-quality production。
V. The results are low. Grape results are generally around 30 centimetres from the ground. An appropriate increase in the results of grapes is required when the rainfall is high and the rains are high, and when the disease is severe, especially when the lower ear of grapes not only suffers early but also in large quantities, it is more severe near the soil. The increase in the outcome is therefore effective in mitigating the harm, from the stage of larvae to the start of cutting more than one metre of branches by about 70 centimetres, and because of the high growth advantage, the ears are concentrated in the first half of the branch, effectively increasing the result area by binding more than 70 centimetres above the ground. By the same token, pre-winter cutting of the resulting tree should also result in six to nine sprouts, depending on the length of the branch, and the 40 cm branch should be cut。
Spring grape management
Embroidered water and fast-acting nitrogen fertilizers: at this stage, the gardens under condition should be fully ploughed in time to ensure that they are lumbered. It is precisely at this time when the buds continue to divide and the new sprouts begin to flourish, when grape cultivation requires a large amount of nutrients, resulting in the use of rotting human urine to mix 0. 2 per cent of urea. This fertilization was about 15 per cent of the year。
Scratch, stubble, and sprout: the result is that the winter sprouts on the mother branch should be sowed. Too many buds, easy to waste nutrients, and weak trees, are not good for sit-ins; but if they are too few, they tend to thrive and cause severe flowers to fall, so care must be taken to wipe them down. Usually, when there are multiple buds on a parent branch, one sprouts every 15 to 20 centimetres, two to five new stubs per parent stubble, and the rest removed from the base. And when a bud is gravitated, it is the flowerless sprouts or the weak sprouts of the twin sprouts, and only a single eye is left behind. Of course, in order to ensure production, it is also possible to decide whether or not its scrolls will be kept in the form of new leaves of up to four or five, but this is a waste of more nutrients。
(b) setting of chickens: five leaves for heart before the flowering of the fresh ones, and eight leaves for heartless ones. After heart breaks, a large number of dosages emerge, leaving only one or two dosages at the top and two leaves to be taken repeatedly, grapes grown and the rest wiped out. It must also be properly tied according to the length of its growth。
(c) treatment of bouquets: in order to ensure the rate of hysteria, one fifth of the lumbers is usually removed manually and 0. 3 per cent bob and 0. 5 per cent urea are sprayed during the flower season. It takes five days for the chickens with more results to be artificially fertilized and then packaged。
Weeding and disease prevention in china: prevention of disease begins when grapes start to grow from three to five leaves, spraying every 7 to 10 days, especially after rain, and increasing the protection of spraying, with attention to the cultivation of grass. This period was dominated by raisin, pox, ashilosis, rusty etc. For example, black pox can be dealt with 8,000 times as dupont and asymptomatic can be dealt with 1,500 times ash. In addition, treatment can be provided with 800 times the polybacterium, 800 times the dyson manganese zinc and 800 times the dyson zinc。
