<h1 class = "pgc-h-arrow-right" >, bud germination and spike growth</h1>
(1) For plants that have not yet germinated, in addition to dripping water to promote germination, spray the foliage surface with 2% benzylaminopurine (cytokinin) 15 ml plus 300 grams of brown sugar mixed with 15 kg of water to drip, and at the same time prune the inner chamber branches, weak branches and overly dense branches to promote the germination of the top buds.
(2) The top buds have germinated 3 to 5 cm, and the leaf axils have not seen red spots, and the top buds are sprayed with drip water with 15 kg of anthropoline 8-10 ml produced in Guangxi Yulin (or 40% ethylene water agent 3-4 ml + 15% paclobutrazol powder 7.5 g). For the top buds have germinated 5 to 8 cm and no red dots with anthrin 12-15 mm or 40% ethylene 4-5 ml 115% paclobutrazol 7.5 grams with water 15 kg spray top bud wet to drip water, the tree is weak, the temperature is high appropriately reduce the amount of ethylene and palphodole, to 3 to 5 days after the spray leaf shedding, does not hurt the flower spike spindle for the degree. It can also be used for other defoliation and flower-promoting agents sold on the market, and it is recommended to test it first and then apply it in a large area.
(3) Prevent flower spikes from rushing. When the top bud germination is in the "rosette shape", spray with 40% ethylene water agent 3 to 5 ml + 15% paclobutrazol wettable powder 7.5-10 grams with water 15 kg, or Guangxi Yulin 8-10 ml with water 15 kg. When the top bud germinates 5 to 8 cm, both red dots and small leaves, the flower barley node is thin and elongated too fast, you can use 40% ethylene water agent 2 a 3 ml + 15% paclobutrazol 7.5 grams with 15 kg of water or with Guilin Guikai Biotechnology Co., Ltd. production of gui blossom fruit a package of water 30 kg, spray top bud flower barley once, inhibit the leaflets, so that the flower spikes grow slowly, promote the flower grain thick, improve the fruit setting rate.
(4) Flower spikes are topped. When the main axis of the flower spike grows to 11 to 12 cm, leave 10 cm to pluck the top, break the apex advantage, promote the lateral flower spike extraction, cultivate short and strong flower spikes, and reduce the occurrence of punching shoots.
(5) If potassium fertilizer has not been applied since November last year, because of drought, apply potassium fertilizer once, and apply it in the rain or ditch. For weak trees and trees with more flower spikes, compound fertilizer can be applied appropriately and phosphorus and potassium fertilizer can be added to promote flowers and flowers. At the same time, cover the tree tray to reduce water evaporation and keep the soil moist.
(6) Thinning diseased insect branches and growing over-dense branches, or combining the top of the press to open a small skylight to prune to improve ventilation and light transmission, save nutrients, and promote the development of the remaining flower branches.
(7) Thinning flowers. For trees with a flowering panicle rate accounting for more than 90% of the last branch, 30-40% of the total flower branch rate is removed according to the strength of the tree.
<h1 class = "pgc-h-arrow-right" > second, the flowering and fruiting stage</h1>
(1) Introduce bees into the park to promote pollination, and place 2 boxes of bees every 10 acres to improve pollination rates.
(2) Shake the flowers in the rain and shake the water droplets to prevent the flowers.
(3) In case of high temperature or drought during the flowering period, spray the flower spikes with water once a day to promote the fruit.
(4) Remove the branches of "ghost broom disease". Orchards with the hazard of "ghost broom disease" should be pruned as soon as possible to the remaining diseased flower spikes, diseased fruit spikes, and diseased branches, and collected and burned.
<h1 class = "pgc-h-arrow-right" > third, young fruit stage</h1>
(1) Fertilize the strong fruit, implement 2 kg of compound fertilizer according to each 50 kg of fruit, and add 1 kg of potassium chloride or potassium sulfate.
(2) For trees with a large amount of fruit hanging and the fruit hanging panicle rate accounting for more than 90% of the last branch, when the longan fruit is as large as a soybean, the fruit panicle and fruit grain are appropriately thinned, reducing nutrient consumption and promoting the development of the remaining fruit. The sparse fruit spike adopts the method of "seeing three sparse one" or "seeing four sparse one", that is, the adjacent three spikes cut one panicle, or the adjacent four spikes cut off one panicle. The thinning grain adopts the method of "arc snippetuation plus digging and sweeping". After the fruit grains were thinned, 60-80 grains were left in the single panicle of Shijiao, 40-60 grains were left in the single panicle of Chuliang, and 40-60 grains were left in the single panicle of Guiming No. 1 and Guifeng early.
<h1 class = "pgc-h-arrow-right" >4. Pest control</h1>
Mainly control bugs, long tarsal fireflies, etc.:
(1) The control of bugs can be sprayed 800 times by 90% of the enemy or 25% of cypermethrin (to kill the salix).
(2) The control of long-tarsal fluorescent leaf nails can be sprayed with 20% chloryanide dichloride (wearing the first nail) 1000 times; or 26% bromide cyanide. Marathon (specifically kills hard shell worms) 1000 times spray kill.
