Growth characteristics of apples
Apple prefers a low temperature and dry environment,and also has to have certain cold resistance and heat resistance.The suitable growth temperature is about 15-23℃.When the temperature is lower than minus 10℃ or higher than 32℃,it is not conducive to apple growth,
Apple trees like light and can only grow and develop normally under sufficient sunlight.When there is plenty of light,photosynthesis is strong,and the yield and quality will be higher.When there is insufficient light,the plant will suffer from excessive growth,weak branches and leaves,poor resistance,decreased flowering and fruit setting rate,and poor root growth.
During the flower bud differentiation and fruit ripening period,it is required that the air is relatively dry and the sunshine is sufficient.If conditions are suitable,the fruit surface will be smooth,the color will be bright,and the flower buds will be full.If it is overcast and rainy,it is easy to cause excessive growth of branches and leaves,poor flower bud differentiation,decreased yield,increased pests and diseases,and poor fruit quality.
Apple is more suitable for growing in deep soil layer,loose and fertile soil,good drainage,rich in organic matter,apple has a certain ability to resist acid and alkali,the soil pH value of about 5.5-7.5 is more suitable.
The growth management cycle of apples can be roughly divided into the dormancy period,bud break period,flowering period,fruit setting period,physiological fruit drop period,fruit enlargement period,color change period,and maturity period.For apple trees in full production,it generally requires 1 kg of pure nitrogen(N),0.4 kg of pure phosphorus(P2O5),0.4 kg of pure calcium(CaO),and 0.8 kg of pure potassium(K2O)to produce 100 kg of apples.It is necessary to increase the application of organic fertilizer,and it is recommended to combine organic and inorganic fertilizers.
Nutrient management plan
Phenological period | Use a fat solution | Purpose of management |
Base fertilizer | Compound fertilizer 90-120g/m2+JINMAI-Kanguo Lifeng®soil conditioner 30-60g/m2 | Fertilize the soil to promote root germination,supplement medium elements calcium and money,increase the content of organic matter,promote nutrient absorption,and store nutrients for the next year's branch,leaf expansion and flowering; |
stages in germination | 1.Apply 6mL/m2 of JINMAI-Green Sum® Seaweed essence solution 2.Spray JINMAI®Green Cell Excitation Energy L-Amino peptide solution 1000 times on leaves | Supplement tree nutrition,promote spring shoot growth,promote root development,increase chlorophyll content,increase leaf thickness and leaf area,improve flowering and fruiting rate,prevent late spring cold. |
Florescence | 1.Spray 1000 times of JINMAI-Blooming® before flowering,and spray once after 15 days 2.In case of low temperature weather,1.5g/m2 of JINMAI-Cuikuo® Low temperature broken algae essence can be sprayed,and JINMAI® Green Cell Excitation Energy L-Amino peptide solution can be sprayed on the leaves at 1000 times | It is conducive to improving the fruiting rate of flowering,and it is easy to occur natural disasters such as rain,snow and late spring cold.Pay attention to preventive work.If freezing occurs,timely remedial measures should be taken. |
Fruit setting period | 1.Apply JINMAI-Baozhilin® Series macroelement 19-19-19+TE 15g/m2; 2.Apply 7.5-15g/m2 of JINMAI Harvest Energy®+3mL/m2 of JINMAI-Yiweipu® Glucan Calcium 3.Spray 800-1000 times of JINMAI-Blooming® High efficiency flower promoter on the leaves | Reduce the physiological fruit drop caused by the competition for nutrients,protect flowers and fruits,and improve the fruit setting rate. |
Fruit enlargement period | 1.Apply 3mL/m2 JINMAI® Green Cell Excaitation Energy Marine fish protein concentrate+JINMAI-Baozhilin® Series macroelement 16-8-32+TE 15g/m2 2.Spray 800-1000 times of JINMAI Yiweipu® Ca-Mg-B-Fe-Zn-Mn-Mo on the leaves | Promote fruit enlargement,relieve the contradiction between flower bud differentiation,fruit enlargement and branch growth,supplement tree nutrition,supplement calcium and iron and other trace elements,and prevent bitter pockmarked disease. |
Transition period | Apply 800-1000 times of JINMAI-Thousands Red®+1000 times of potassium dihydrogen phosphate on the leaf surface | Promote the secondary enlargement and coloring of fruit,improve the grade of fruit,improve the sugar content of fruit,improve the appearance quality,promote coloring,improve the commercial value. |
Maturation period | 1.The original driving force is 15g/m2 2.Apply 1000 times of JINMAI Yiweipu® Ca-Mg-B-Fe-Zn-Mn-Mo on the leaf surface | Quickly replenish nutrients,restore tree vigor,promote root development,and prevent premature leaf fall. |
