Abstract
The invention discloses a technology for planting citrus. The technology comprises a step (1) of trimming citrus trees in January, a step (2) of trimming the citrus trees continuously and cleaning a garden in February, a step (3) of applying 500-100 g of urea or 100-200 g of microbial organic fertilizer to each 3-year-old young tree, applying 200-400 g of urea or 500-1000 g of microbial organic fertilizer to soil of each adult fruiting tree and combing 45% of 100-200-fold crystal calcium polysulfide and 0.3-0.5% of urea and 0.3% of monopotassium phosphate for leaf surface spraying to promote spring shoots in March. Reasonable trimming, spraying and fertilization measures are performed for the citrus trees in different months, and the method effectively avoids the damage of diseases and insect pests to the citrus trees and enables the citrus trees to grow healthily and be high in yield and good in fruit quality.
Description
Technical field
The present invention relates to a kind of planting technology, particularly a kind of planting technology of oranges and tangerines.
Background technology
China is one of important original producton location of oranges and tangerines, oranges and tangerines aboundresources, and improved seeds are various, have the cultivation history of more than 4000 year.Through cultivated since long, selection, oranges and tangerines have become the precious fruit of the mankind.
But existing oranges and tangerines planting technology systematicness is poor, and mandarin tree easily occurs damage by disease and insect, and then cause yielding poorly and the technical problem of fruit difference.
Summary of the invention
In view of this, the object of this invention is to provide a kind of planting technology of oranges and tangerines, to solve the problem that existing oranges and tangerines planting technology well can not prevent oranges and tangerines damage by disease and insect.
The planting technology of oranges and tangerines of the present invention, comprises the following steps:
1) in the January, mandarin tree is pruned, and with 45% crystal lime polysulfies 100-200 times liquid or machine oil emulsion 100-200 Bei Yeqing garden, and to orchard carry out appropriateness irrigate;
2) in the February, continue to carry out pruning and clear garden to mandarin tree;
3) in the March, urea 50-100 gram or the every strain 100-200 gram of biological organic fertilizer are executed to the every strain of the raw treelet of 1-3; Annual bearer soil is become to execute urea 200-400 gram/strain or biological organic fertilizer 500-1000 gram/strain; And urge the spring tip with the crystal lime polysulfies 100-200 times liquid of 45% in conjunction with foliage-spray 0.3-0.5% urea+0.3% potassium dihydrogen phosphate;
Before and after rudiment, to red, the yellow spiders of sprayer spraying fruit tree 20% pyridaben 2000 times of+5% hexythiazox 3000 times of liquid control, at the beginning of by the end of March to 4 month, prevent and treat bud maggot with 40% octyl sulfate, 1500 times of liquid spray ground and tree crown;
4) in the April, treelet is respectively watered and executes an available nitrogen potash fertilizer; Before flowering, by 20% fenpropathrin, 2500 times of liquid control tangerine leaf mining first and pernicious chrysomelid; Post flowering selects 40% propargite or 25% azacyclotin, 1500 times of red, yellow spiders of liquid control, can kill 1000 times of liquid prevent and treat anthracnose with 58%; And flower is protected to adult navel orange tree BA+GA or slight girdling;
5) the middle ten days and the last ten days in may a n-formyl sarcolysine quick-acting fertilizer is respectively executed to treelet, short early summer shoot, 25% buprofezin, 2000 times+machine oil emulsion 300 times or the alone 0.5% fruit holy 1000 times of liquid control a red-spotted lizard class of early and middle ten days in may, aleyrodid and aphids, continue that control is red, yellow spider and anthracnose;
6) in the middle ten days and the last ten days in June, a summer shoot fertilizer is respectively executed to treelet, the last ten-days period to early July bearing-age tree execute the 500-1000 gram/strain of fruit-promoting fertilizer 30% potassium sulfate type Chemical Mixed Fertilizer; And continue control a red-spotted lizard class, aleyrodid, aphid and longicorn; Artificial fruit thinning is carried out in the middle ten days and the last ten days in June;
7) July early and middle ten days an autumn growth fertilizer is respectively executed to treelet; Spraying 1-2 0.2% potassium dihydrogen phosphate+0.3% urea, reduces dehiscent fruit; And prevent and treat shallow leaf moth, blister mite and aphid with 1.8% Avermectin, 3000 times of liquid;
8) in mid-August, autumn growth fertilizer is executed to treelet, and continue control leaf miner, aphid and blister mite, and prevent and treat anthracnose; And a shaping is drawn to treelet;
9) in the middle ten days and the last ten days in October to the spray of bearing-age tree late-maturing oranges and tangerines orchard 10-20ppm2,4-D, and use sufficient fertilizer of surviving the winter and prevent shedding in winter;
10) the middle ten days, 4-D, prevented shedding to bearing-age tree late-maturing oranges and tangerines orchard spraying 20-40ppm2 in November;
11) winter pruning is carried out in the last ten-days period in December, wipe out deadwood, sick branch, branch group after weak branch group, the result of bouncing back, fall behind shedding branch group and dredge delete close weak branch group, and carrying out clear garden in winter, the crystal lime polysulfies 100-200 times liquid with 45% or machine oil emulsion 100-200 times of liquid spray orchard.
Further, at the end of of two months, in orchard, sow green manure or the short bar economic crops of shallow root.
Further, part prevents and treats physiological fallen fruit to navel orange fruit preservative in conjunction with foliar application in may, other kind spraying 0.2% potassium dihydrogen phosphate+0.2% boric acid 1-2 steady fruit.
Further, being coated with the yellow ester of plan at the beginning of June to navel orange prevents navel yellow.
Beneficial effect of the present invention: the planting technology of a kind of oranges and tangerines of the present invention, its by reasonably the pruning mandarin tree of system, spray the measure such as medicine, fertilising, effectively prevent the injury of damage by disease and insect to mandarin tree, make the growth that mandarin tree can be more healthy, output is higher, and fruit is better.
