Orchard flowering management points

Nanyang Town is one of the production areas in Shanghang County. The total planting area of ​​the town is 37.0hm2, of which the fruit orchard area is 26.5hm2. The planting area of ​​the fine variety 'Huangwuxing' is expanding year by year. According to statistics, the total production in 2012 was 401.46t. The mangosteen produced has a moderate flesh-thickness and hardness, and the flesh is bright and slightly yellowish and sweet, with good skin and toughness and good taste, and is resistant to storage and transportation.

This is a fruit tree that blooms in winter and is harvested from spring to early summer. It takes about 100 days from flowering to final flowering, and the amount of flowers is large. There are about 50 to 100 flowers per panicle, and as many as 200 or more; In order to ensure sufficient and robust inflorescence overwintering and ensure the bumper harvest in the coming year, we must pay attention to the following points in management.

1. Baohuabaoguo: In late December and mid-January of the following year, it takes 2/3 to use 0.25% potassium dihydrogen phosphate plus 0.2% urea and 0.1% borax solution and 0.1 to 0.2% fenfenwei leaf spray. Shi, Xie Hua period with 10mg/L Gibberin foliar spray, increase the rate of fruit set.

2. Remove winter shoots: Due to the large amount of rainfall and warmer temperatures from November to early December of this year, the short and weak winter shoots at the base of flower spikes should generally be removed early to reduce nutrient consumption.

3. Thinning flowers: According to tree vigor, for trees with too many flower spikes, some spikes should be cut off. The principle of sparse flowering is to remove weak (plant diseases and insect pests) flowers, to leave strong (healthy) flowers, to stay small, and generally to remove 1/3 to 1/2 of the total tree flower volume. When the flower spikes are all taken out, they are sparsely flowered. Go to the top of the flower spike and base several small flower axis, leaving 4 to 6 small flower axis in the middle, leaving 1 to 2 flowers for each flower axis; at the same time, we must eliminate premature or late flower spikes to make the fruit maturity consistent. The value of commodities.

4. Antifreeze damage: Each tree is used to burn earth or rubbish fertilizer, mountain bark mud to cover the root of the fruit tree 10 to 15 cm thick; then use dry straw or thatch to cover the earth, in order to increase soil temperature, protect the root group, increase Fertilizer points, will help the tree safe winter. Before the onset of the cold wave, foliar fertilizers can be sprayed on the roots, that is, from November to January, with 0.2% urea and 0.3% potassium dihydrogen phosphate mixed solution spraying, 2 or 3 times per month, can significantly increase the tree Body cold resistance.

5, control flower rot: 45% Dasheng M wettable powder watered 800 ~ 1000 times liquid crown spray, or with 50% carbendazim, 70% thiophanate-methyl 800 ~ 1000 times spraying spray fog canopy 2 ~ 3 times, once every 5 to 7 days.

6. Insect-preserving and flower-keeping: Insect pests during the flowering period mainly include the cockroach bird swallow butterfly. Should strengthen the orchard inspection, discover the gall of panicles, combine the sparse flowers to timely remove the insect buds, concentrate burning or deep burial, reduce the source of insects; or use 800-1000 times of 90% crystal trichlorfon before and after flowering Liquid or canopy spray of 3000 times of amethrin salt emulsifiable concentrate 3000 times, can also use 40% speed culling 2000 to 3000 times liquid crown spray. Avoid using dichlorvos to remove insects.
