Citrus Nutrient Management

January

Flower bud morphological differentiation period;winter shoot germination period;

Promote flower bud differentiation and control winter shoots.

According to the tree,dig holes 40-50 cm deep around the citrus plant,then fill them with organic fertilizer and cover with soil

Except for wintering anthracnose and scab,all the pests and diseases in this month are in the state of lying in wait for wintering

February

Spring bud growth period

Promote flowers and strengthen flowers

1Apply JINMAI-Green Sum^®Seaweed essence 6-7.5mL/square meters,

2Apply JINMAI-Kanger Green^®+JINMAI-Yiweipu^®Glucan Boron 1000 times on the leaf surface

In this month,some pests and diseases are in a dormant state,a small number of overwintering red spiders and scale insects begin to lay eggs;sooty bark disease and anthracnose begin to infect.

March

Spring shoot growth period,flower bud period,initial flower~full flower.

Chrysanthemum flowers,pollination,disease and insect control.

1.Apply JINMAI Motive Power^®7.5-15g/m2,1-2 times

2.Apply 800-1000 times of JINMAI-Blooming^®+1000-1200 times of potassium dihydrogen phosphate on the leaf surface,spray 1-2 times;

This month is the peak period of egg production of red spider mites;the malignant leaf beetle gradually emerges;the period of infection of scab disease,ulcer disease and acute anthrax.

April

Bloom~fall period,

The first physiological fruit drop occurs during the early fruit development period.

Promote fruit and prevent disease and insect

1.Apply JINMAI^®Green Cell Excaitation Energy Marine fish protein concentrate 6mL/m2+7.5-15g/m2 19-19-19 macronutrient water-soluble fertilizer,once every 15-20 days,and use twice continuously

2.When two-thirds of the flowers have withered,spray 1000 times of JINMAI-Blooming^®on the leaf surface+1000 times of Jinxian Yiwu Puglycoprotein calcium boron;

3.Spray JINMAI-Fruit Strength^®800-1000 times+JINMAI-Yiweipu^®Complex acid Glucan Calcium 1000-1500 times every 5-7 days after flower

If the red spider mite is not well controlled in this month,the red spider mite will occur seriously;flower bud maggots will occur;acute leaf blight will begin to occur;the best period for sooty bark disease infection;citrus nematode disease will occur(including citrus root-knot nematode and citrus semi-puncture nematode).

May

The second physiological fruit drop period,young fruit development period,summer shoot germination period

fruit retention

1Apply 14-8-28-6 CaO-0.1B-0.1Zn macroelement water soluble fertilizer 15g/square meter,once every 15-20 days,and use continuously 1-2 times

2.Apply 1000 times of JINMAI-Superior Flower&Fruit^®before the second physiological fruit drop,every 15 days,and use continuously for 1-2 times

3.Before the second physiological fruit drop period,carry out the second ring cutting(about 15 days before the second fruit drop period)

The onset period of scale insects and whiteflies in this month:red spider mites occur selectively in areas;anthracnose,scab and yellowneck diseases complete primary infection and reproduce in trees.

June

The second physiological fruiting end period,summer shoot period

Remove summer shoots and protect fruit

1.Apply 15g/square meter of JINMAI Harvest Energy^® , and use once every 15-20 days

2. Spray 800 times of JINMAI-Healthier Crop^®  Reproductive growth promoter on leaves

This month is the peak period of infection of sap disease,citrus root-knot nematode disease and citrus semi-puncture nematode disease,and other diseases and pests are similar to those in May.

July~August

Fruit enlargement period,summer shoot period.

Remove summer buds to prepare for autumn shoots

1.Apply compound fertilizer in the ditch, accounting for 40% of the annual fertilizer amount, 15-20 days before the release of autumn shoots

2. Apply 15g/m2 of 16-8-32 macronutrient water-soluble fertilizer every 15-20 days

Chronic anthrax began to occur;autumn shoots red spider gradually appeared;rust mites occurred;aphids,black stink bugs,leaf miners and whiteflies occurred seriously.

September~October

Autumn tip turns green,the period of maturity,the rapid enlargement of fruit.

Let the autumn shoots grow,and the shoots will grow strong and the fruit will grow strong

1.Apply 15g/m2 of 16-8-32 macronutrient water-soluble fertilizer

2.Apply 1000 times of JINMAI-Thousands Red^® to the leaves

Papilio,Leaf roller,inchworm occurrence;red spider,rust spider second peak;anthracnose,ulcer disease repeated infection;citrus nematode disease occurrence second peak;

November~December

Fruit maturity,flower bud differentiation and winter shoot occurrence

Strong shoots and fruits

1.Apply 15g/m2 of 16-8-32 macronutrient water-soluble fertilizer

2.Apply 1000 times of JINMAI-Thousands Red^® to the leaves

When citrus nematode disease occurs seriously,functional bio-fertilizer can be used to supplement soil organic matter and also have a good control effect on citrus root-knot nematode and citrus semi-puncture nematode;other diseases and insect pests are the same as last month.
