I. 12-month management and technology of Citrus sinensis

1. January (clearing the garden)

(1) Before and after the big cold, dig a deep ditch, ditch application of 2.5-5kg of rotted organic fertilizer + 0.25kg of calcium-magnesium-phosphorus fertilizer.

(2) Spray drugs to eliminate overwintering pests, and clean up diseased branches and leaves.

2, February (spring bud budding period)

(1) in about 15 days before the end of the twig (late February spring twigging), water drenching 0.1% urea solution or high nitrogen compound fertilizer solution.

(2) After applying fertilizer, cut off the thick autumn tips to promote the sprouting of spring tips.

(3) After pruning, spray a drug, and at the end of February when the shoots sprout to 1cm, spray a drug again to kill citrus woodlice, whiteflies, aphids and other pests, and at the same time do a good job in the prevention and control of ulcers and anthracnose.

3, March (spring tip sprouting growth period)

(1) spring tip sprouting pre-spray high nitrogen foliar fertilizer, when the spring tip grows to more than 10cm, spray high potassium + water soluble organic fertilizer.

(2) For the overly dense spring tip pruning, generally retain 2-3 spring tips per fall stake.

(3) In early to mid-March, before the leaves turn green, spray drugs to kill citrus woodlice, whiteflies, aphids, red spiders and so on.

4, April (spring growth period, summer sprouting period)

(1) In mid-April, after the rain, sprinkle 0.1% urea solution or compound fertilizer solution.

(2) For the spring tips that will mature soon to pick the top, for the mature spring tips, select the thick spring tips for short cutting, to promote the development of summer tips.

(3) After top removal or pruning, spray a drug to prevent and control red spider, leaf miner moth, mealybugs and so on.

5, May (summer growth period)

(1) through the foliar supplemental nutrients, to promote the growth of summer tips. The first stage is mainly high nitrogen foliar fertilizer, and when the summer tip grows to more than 10cm, spray high potassium + water-soluble organic fertilizer + micro-fertilizer.

(2) For the overly dense summer tips to be erased, each branch of the autumn stake to retain 2-3 strong summer tips.

(3) In mid-May, spray drugs to kill citrus woodlice, leafminer moths, mealybugs and so on.

6, June (summer tip growth period, late summer tip pumping period)

(1) after the rain to impose strong tip fertilizer, to fast-acting compound fertilizer is given priority to.

(2) For the summer tips that are not old and mature, spray high potassium + water-soluble organic fertilizer + micro-fertilizer.

(3) For the summer tips that are not ripe, remove the tops to promote ripening; for the ripe summer tips, choose the thick summer tips (more than 30cm) and shorten them.

(4) After topping or pruning, spray drugs to prevent woodlice, leaf miner moths, mealybugs, aphids, asphids and so on.

7, July (late summer tip growth period)

(1) for too dense late summer tips to erase, remove the weak and leave the strong (each branch of the fall stake to retain 2-3).

(2) At the end of July, furrow application of ripe organic fertilizer and urea.

(3) For the late summer tips that are not ripe for picking, to promote ripening; for the ripe late summer tips, choose the thick late summer tips (more than 30cm) short cut.

(4) After top removal or pruning, spray drugs to prevent leaf miner moths, mealybugs, whiteflies, aphids and other pests, and do a good job of preventing and controlling ulcers and anthracnose.

8, August (autumn tips sprouting growth period)

(1) for too dense autumn tips for pruning, will be weak tips cut off, retain 2-3 strong tips.

(2) Through the foliar supplemental nutrition, to promote the growth of autumn tips. Spray high-nitrogen foliar fertilizer during the sprouting period, and spray high-potassium + water-soluble organic fertilizer + micronutrient fertilizer when the new autumn tips grow to more than 10cm. If it is the third year of production of plants, spray 1-2 times of potassium dihydrogen phosphate + water-soluble organic fertilizer + microfertilizer containing high boron, zinc and magnesium.

(3) When the new autumn tip grows to more than 10cm, sprinkle high potassium quick-acting compound fertilizer after rain.

(4) After top removal or pruning, spray drugs to control woodlice, leaf miner moths, aphids, mealybugs and so on.

9, September (early autumn tips ripe, late autumn tips sprouting)

(1) For the autumn tips that have not yet ripened, spray high potassium + water-soluble organic fertilizer + micro-fertilizer.

(2) For the autumn tips that are not yet mature, pluck the tops; for the autumn tips that are already mature, choose the thick autumn tips (more than 30cm) and cut them short to promote the late autumn tips. If it is the third year into the production of plants, in late September, foliar spraying 1-2 times potassium dihydrogen phosphate + water-soluble organic fertilizer + containing high boron zinc magnesium micro-fertilizer.

(3) After top removal or pruning, spray drugs to control woodlice, red spider, leaf miner moth, aphids and so on.

10, October (late fall tips growth period, old maturity)

(1) for too dense late fall tips, cut off the weak tips, retain 2-3 strong tips.

(2) In the pre-emergence period of late autumn tips, high nitrogen foliar fertilizer is the main focus, and when the new late autumn tips grow up to 10cm, spray 2-3 times of high potassium + water-soluble organic fertilizer + micro-fertilizer.

(3) When the new late autumn tips grow to 10cm, sprinkle high potassium quick-acting compound fertilizer on the ground after rain.

11, November to December (late autumn tips ripe, winter tips pumping period)

(1) will be unripe late autumn tips and new winter tips erase, reduce tree nutrient consumption.

(2) For fruit trees that do not bear fruit in the coming year, spray 100ppm of gibberellin solution in late November. For the next year fruit trees, spray 1-2 times water-soluble organic fertilizer + 0.5% potassium dihydrogen phosphate + containing high boron zinc magnesium micro-fertilizer.

(3) Spraying drugs to exterminate overwintering pests, and at the same time, clean up the diseased branches and leaves.

Second, where is the origin of Vodka concentrated
