Red net news news, zhang leungbo, is now entering flowering or early fruiting years. Across the province, a number of orchards face serious challenges as a result of the ongoing rains and oligarchy weather. In order to help farmers respond effectively to the disaster and minimize losses, a number of key technical measures have been proposed by experts in the technical system of the fruit industry in hunan province。
The experts emphasized that drainage and moisture was the primary task of the current orchard management. The farmers should immediately clear the drains inside and outside the orchards and ensure that the water is removed within 24 hours. Low-lying orchards are required to dig deep trenches between rows and plant them. When the rain stops and the surface drys slightly, the tree plate (10-15 cm) should immediately be ploughed to break the slabs, increase the air permeability of the soil and promote the restoration of the roots。
Vegetable fruit management: change from "sorting" to "precious"
Poaching is not sufficient in itself, it is strictly forbidden to do so in large quantities, and all robust flowers should be preserved until the fruit is stabilized. Vegetable farmers are required to catch rain breaks (from 9 to 11 a. M.) for artificial dotting or liquid spraying, which can be used to extract pollinators from quilts, or to assist with electric pollinators. At 70 per cent of the sheath, the sunbath sprays acrylic acid (ga3), 0. 2 per cent of potassium phosphate and 0. 1 per cent of boron, which, if the tree is weak, can be added to the amino acid leaf fertilizer and increase the seating rate。
Scientific fertilization: better on the ground than underground application
During the period of damage to the roots, the immediate practice of heavy fertilization in the ditch is prohibited in order to avoid causing damage to the roots. The experts recommended that the focus be on folic fertilization, the spraying of potassium dihydrohydrophosphate, urea and micronutrients (calcium, magnesium) every 7 to 10 days, and that tree nutrients be rapidly replenished。
Pest and pest control: cleaning is the key
The fruit farmers should be able to remove the flowers, rotten fruit, disease branches from the garden in a timely manner, take them out and bury them or burn them, and reduce the disease base. One or two days after the rain stops is the golden phase of the spray. The fungicide is recommended as dysen-zinc and ethylene acetate (or ester) to combat lignosis and scabies; insecticides may be used for the treatment of aphids or high-efficiency chlorocyanethrin for the treatment of aphids and heartworms. It needs to be noted that during flowering periods, spraying is avoided to the extent possible, so as not to affect pollination。
Tree management: controlling lighting
For trees with few flowers, fresh and long branches have been removed in a timely manner, and canopy canopy has been improved and nutritional consumption reduced. In the case of frozen or severely watered trees, when new hairs are emerging, the dead branches are cut off and new branches are promoted。
Experts gave a central focus to different species. Peach trees are extremely impregnable, prone to adhesive gel and lignogenic disease, drainage is the first priority, and the focus is on aphids and lignogenic disease. Pear trees need to be pollinated, and artificial pollination is a top priority and black star disease is strictly protected from the sack. Plum tree sit-in rates are vulnerable to hypothermia and the pyretants are used with precision and care to prevent bacterial perforation。
The experts recommended that fruit farmers should delay the utilisation of fruit until after the physiological fallout has ended and then determine the tree's position so as to avoid the loss of production due to premature twig. In addition, hunan was still in the rainy season in april-may, requiring sustained attention to weather forecasting and early drainage and prevention。
