On a mayday, warmer temperatures and more rain are critical periods for grape-spilling, flowering and symmetrical gold. I always say grapes are three, seven, and the harvest is due in may。
Every year, around the time of the summer, the year, the vineyards in the north and south enter the busiest care phase of the year. Many farmers are confused and grow grapes in the same way, some of them bending their vines after the fall, and a string of branches over them; some of them grow and fall in fruit, while the ears are small。
Essentially, the difference is hidden in the four key management points of may. As long as these four things are taken into account, whether they are field grapes in the open or courtyards, this fall will be a year of full and productive production. The following is a detailed account of the experiences of old grape cultivation in the northern and southern regions。
I. Sprung the whole branch in time to control its strength long
The rapid recovery of temperature in may, the rapid sprouting of grapes, the growth of new and sub-crazy, if left unchecked, the lack of ventilation and poor internal ventilation not only consume large amounts of nutrients, but also lead to later flowering, falling fruit and disease。
The sprouts are the first priority in may. The principle is to be strong and weak, to be kept secret, and to be fed。
The indeterminate, weak and overlapping buds that have emerged from the backbone and chickens in the spring must be eliminated as soon as possible; the result is to retain robust results on the mother branch and to remove the excess nutrients in time. For those who have grown, do not let them grow crazy, take their time to keep their minds high, inhibit their nutritional growth and concentrate their nutrients on the provision of flowers and fruit。
The real case of the country is that, after growing grapes for more than a decade, the old father of the country, pingdu, has been unable to graze them in the past, and feels that they can produce more, and every may the chickens are so full they can't even breathe. The years are flowering, the fruit is rare, and the fruit is small and perishable。
He studied the whole branch of may with a farmer for almost three years, and in the week following the summer, he finished the sprouts, swirling and grafting, keeping the branches rationally per acre and ventilation in the garden. Only this step has been adjusted, with a marked rise in the rate of symmetry, with the symmetry of the symmetry directly up to the previous stage, and after autumn production 20 to 30 per cent higher than in previous years。
This is a reminder of the geographical differences between the north and the south, where the frostless period is short and the whole branch is too early and thin; and the heavy rainfall and moisture in the south, which makes it necessary to increase the intensity of the branches in order to avoid the disease caused by depression and humidity。
Ii. Precautionary management, with pups at the core
In mid-may, most of the varieties of grapes entered the prime and flowering season, which is a critical point in determining how much fruit to sit on. Many farmers lost their grapes, mostly in the form of time management。
First of all, the water must be strictly watered. During the flowering of grapes, the fear was greatest, the soil was too wet, the air in the field was too wet, and there was a high risk that the crowns would fall off and pollinating would be obstructed, resulting in a large number of flowers falling fruit. Unless drought persists, the flowering season will be reduced to a minimum of water and the use of small water sews will suffice。
Second, do hand-aided poaching. One branch of the result should not leave too many flowers, one or two ears of the strong branch, one ear of the mediocre branch, and the weak branch should concentrate on feeding the high-quality fruit. There are too many early ears left, late nutrition cannot keep pace, and the grains are not long enough to be sweet, and they are prone to serious sizes。
At the same time, attention should be paid to the small field climate, during consecutive rainy days, and to the timely removal of drainage ditches and the elimination of water from the garden; in the case of high temperatures and dry winds, slight sprays can be wettened in the evening, avoiding the effects of draught drying on pollination。
The old growers have come to a solid conclusion: the may flower pipe is good, the fall's consequences are rare, the season is stable, and a year's harvest is at the bottom。
Scientific pursuit of nutrients and demand-driven provision
Grapes, from budding and sprouting to flowering fruit, consume a great deal of nutrients throughout the course. May is the critical period for nutrition. Short of fertilizer, the branches are weak, the flowers are thin and the rate is low; but blindly applying fertilizers, the nitrogen fertilizers tend to lead to a long strip of madness and corruption。
The may fertilisation is to be measured in stages, in terms of rationing, less pure nitrogen, more potassium phosphorus, and an appropriate replacement of trace elements。
The pre-emergence leaves are expanded to promote the growth of new and robust growth, mainly through the rapid balancing of fertility; a week before the flowering, the focus is on phosphorus supplementation to improve the quality of pollination and reduce the fall of flowers; and after the bouquet, the pre-fertilization of the inflation is followed in a timely manner by the replenishment of potassium and calcium to prevent post-fracking and fallout, so that the fruit is evenly increased。
Fertilizers are proposed to be applied in the form of shallow-spreading, ground-filled water, not too close to the backbone to avoid the burning of roots; small areas of gardening can be used to produce water for fattening, temperature and long effects, and soil can be improved without hurting the roots。
In terms of geographical differences, the soil of the north is sandy and poorly fertile, which requires a small number of fat pursuits, while the soil of the south is adhesive and rain washes the nutrients quickly, and is followed by appropriate soil preservation and loss reduction. One-time mass of fertilizer, which appears to be a relief, destroys the trees and reduces their harvest。
Iv. Early prevention of disease and insects, early prevention and early treatment, and reduced delivery
High temperature and humidity in may, both during the grape growing season and during the onset of disease and pests. Frosty, asymptomy, black bean disease, sarcophagus, green blindness, etc. All love an outbreak in may, and when prevention is missed, the cost of treating the disease later in life is high, as well as the effects on the leaves, affecting production and quality throughout the year。
Plant protection management insists on prevention and integrated prevention, without waiting for an outbreak to heal。
Day-to-day garden cleaning, timely removal of sick leaves, weak leaves and flowers, bringing out of the fields for deep burial, reducing the origin of the fungi, keeping the shelf ventilated, reducing field humidity and inhibiting the environmental reproduction of the fungi。
Insects focus on green blinding, osteoporosis, which is highly hidden and specializes in the eating of young leaves and flowers, pre-eminence and later foliage and malformation. Physical booby traps can be used in conjunction with the rotation of low-drug-compliant substances, avoiding flowering and affecting pollination。
The real case of the countryside: lee, the zhejiang zhejiang zhejiang grape grower, who neglected early disease prevention in may in the past years, had spent one year in a rainstorm after a small year, had been affected by the spread of frosty disease, had lost the leaves, had lost half the fruit, and had spent a year in vain。
In the first half of may, preventive care began, with the clearing of gardens, whole branches, rational wetting and early prevention at gas-saving points. In the last four years, there have been almost no major outbreaks of disease, fruit is good and clean, and purchase prices are much higher than those of neighbouring farmers。
Old-age farming experience has never been empty-minded. In may, the bug stand was secured, the fall was full of baskets, grape cultivation was a three-minute, seven-man system, four key points were rounded up, one step behind the other, and the pace was affected。
Final summary
Overall, in may, grape management caught these four points: germinate whole branch control, bouquet protection fruit, scientific enrichment, disease prevention and pest prevention。
There is no high-level skill. It is the experience of land-based farming that has been learned by generations of old farmers. As long as you follow the ablution, follow the long tube, and keep the may basics in place, and don't worry about late production, until the golden fall season, the vines will be full of fruit and a string of bends, and the harvest will grow。
