Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a flower and fruit management method of autumn anti-season Or citrus.
[ background of the invention ]
The Wo oranges are successfully introduced in the Wuming district of Nanning city of Guangxi in 2012 for the first time, and the Wo oranges are found to be very suitable for the climate and soil of Guangxi, have good yield and quality and are superior to other provinces. Since the Wo oranges grow explosively in Guangxi, the yield is increased sharply, 1 month to 3 months in 2019, Wuming Wo oranges are out of stock, part of the price falls to 2-3 yuan/jin, and the planting cost of Wo oranges is low. After 2020, about 300 ten thousand mu of newly planted Wo oranges are expected to have fruit bearing in the high-yield period, and the situation of over demand is more serious.
The method has the advantages that the citrus wovensis blooms in autumn, and when the citrus wovensis blooms in the autumn-winter handover period, rainwater is less, abscisic acid in plant bodies is increased, nutrient elements need to be supplemented timely, growth of the citrus wovensis is regulated through exogenous hormones, transportation of nutrient substances is controlled, and physiological fruit drop is prevented. Because the fruit expansion period partially misses the optimal growth period with abundant rainwater illumination for 5-11 months, the sweetness of the normal cultivation management fruit hardly reaches the optimal quality, artificial sweetening management measures need to be taken to inhibit the vegetative growth of fruit trees, so that nutrient substances are intensively transferred to the fruit, and the sweetening of the fruit is realized. How to adjust the production period of the Wo oranges and to appear on the market by crossing peaks is an important issue for the sustainable development of the Wo oranges industry. The cultivation of the summer oranges in the out-of-season mode can well stagger the market of the summer oranges, and high benefit is obtained.
[ summary of the invention ]
The invention provides a management method for flowers and fruits of summer oranges in an out-of-season autumn, which aims to realize out-of-season flowering of the summer oranges and stagger normal flower and fruit periods.
The method for managing flowers and fruits of autumn off-season Or citrus comprises the following steps:
s1, excavating a ring ditch along a water dripping line of a crown of the fruit tree in the middle ten days of the month 6; cutting the trunk ring skin; trimming the crown and cutting the overgrown branches;
s2, at the end of Laetia 6-8 months, spraying a compound aqueous solution of 15% paclobutrazol wettable powder of 400 times, 25-50mg/L chlormequat chloride, 300mg/L ethephon 200, 5-8g/L monopotassium phosphate and 0.1-0.3g/L boric acid every 8-12 days;
s3, broadcasting compound fertilizer in the middle of 9 months at 0.5-1 kg/plant in the ring trench, and covering soil and burying; spraying a compound aqueous solution of 3000-fold gibberellin emulsifiable solution of 4 percent, 5000 times of the emulsifiable solution, 0.5-1g/L of boric acid and 12-15mg/L of diethyl aminoethyl hexanoate once every 8-12 days at the end of the middle ten days to 10 months of 9 months, thereby realizing the flowering of the fruit trees in 9-10 months;
s4, cutting the trunk of the fruit tree into annular skin in the full-bloom period; 0.8-1kg of calcium magnesium phosphate fertilizer, 0.3-0.5kg of ammonium dihydrogen phosphate and 0.2-0.4kg of potassium sulfate are broadcast at the root;
s5, spraying a compound aqueous solution of 5000-8000 times of 15% paclobutrazol wettable powder, 12-15mg/L diethyl aminoethyl hexanoate, 10-20mg/L kinetin, 5-8g/L monopotassium phosphate and 0.1-0.3g/L boric acid every 10-15 days from the full-bloom stage to 11-middle-month ten days; 0.5-0.8kg of ammonium dihydrogen phosphate, 0.5-0.6kg of potassium sulfate and 3-5kg of organic fertilizer are broadcast at the root part every 20-25 days;
s6, changing the larval fruits into conventional management after the larval fruits in the middle of the month are enlarged;
s7, 45-60 days before picking of the Or: (1) cutting the fruit tree trunk into annular bark; (2) 400 times of the amino acid water-soluble fertilizer is applied every 7 to 10 days; (3) spraying a compound aqueous solution of 0.5-1g/L of glucose, 800 times of amino acid water soluble fertilizer, 5-8g/L of monopotassium phosphate, 200mg/L of ethephon and 5-10mg/L of compound sodium nitrophenolate on the leaf surface every 8-12 days; (4) stopping taking the medicine 15 days before picking;
s8, the pest control of the fruit trees is carried out according to a conventional management method.
The fruit trees do not need to be fertilized for 5-8 months.
The fertilizer does not contain quick-acting nitrogen.
The depth of the excavation annular groove is 25-30cm, and the width is 15-20 cm.
The amount of the branches cut by the trimmed crown is not less than 1/5 of the whole branches of the fruit tree.
The trunk of the annular skin cutting is a trunk and/or a branch.
When the trunk of the annular skin cutting is a trunk, the specific skin cutting position is 2-5cm from the junction point of the first branch and the trunk of the fruit tree along the direction from the trunk to the ground.
When the trunk of the annular skin cutting is a branch, the specific position of the skin cutting is 2-5cm from the junction point of the trunk of the fruit tree and each branch along the direction from each branch to the treetop.
The depth of the ring-shaped skin cut is in a cambium between the phloem and the xylem.
The technical scheme has the following functions:
excavating a circular trench: cutting off partial fibrous roots of fruit trees, reducing the activity of root systems, and inhibiting the absorption of water and nutrient substances.
Paclobutrazol: delay the growth of fruit trees, inhibit the vegetative growth and increase the stress resistance of fruit trees.
Annular skin cutting: the products of carbohydrate, protein, amino acid, vitamin, inorganic salt and hormone which block the photosynthesis in the leaves are delivered to the roots of fruit trees, thereby reducing the nutrition supply of the roots, reducing the activity of the roots and inhibiting the vegetative growth.
Chlormequat chloride: inhibiting the elongation of crop cells, making the stem of fruit tree become thick and the leaf color become green, and inhibiting the vegetative growth.
Gibberellin: breaking the dormancy of fruit trees and promoting the vegetative growth.
Boric acid: promoting pollen germination and pollen tube elongation.
Diethyl aminoethyl hexanoate: the absorption of water and fertilizer and the accumulation of dry matters of the fruit trees are enhanced, the flower bud differentiation is promoted, and the water balance in the plant body is adjusted.
Kinetin: has effects in promoting cell division, inducing bud differentiation and development, and increasing stomatal aperture.
Compound sodium nitrophenolate: has effects of promoting cell protoplasm flow, improving cell activity, accelerating plant growth, promoting root growth, strengthening seedling, protecting flower and fruit, increasing fruit setting, increasing yield, and enhancing stress resistance.
Ethephon: has effects in promoting secretion of emulsion, promoting ripening, exfoliation, aging, blooming, promoting fruit ripening, and stimulating wound.
Description of the principle: the early 6 months to the end 8 months are the periods of most abundant rainfall and illumination all the year round, at the moment, the tree body grows most vigorously, and in order to realize the induction of flowering by the autumn anti-season citrus woolly cultivation, the water absorption of the citrus woolly needs to be controlled intensively, and the nutrition transfer is inhibited. Therefore, forced dormancy for at least 2 months or more is carried out from the beginning of 6 months to the end of 8 months, thereby forcing it to stop vegetative growth, and then the suppression conditions are released from 9 months to 10 months, thereby achieving flowering induction.
After the induction blooming is successful, the amount of rainwater is less in the autumn and winter handover period, abscisic acid in the plant body is increased, elements such as calcium, magnesium, phosphorus, potassium, boron and the like need to be supplemented in time, the growth of the oranges is regulated through exogenous hormones, the transportation of nutrient substances is controlled, the application of quick-acting nitrogen fertilizers is controlled, the vigorous growth of young shoots is controlled, and the physiological fruit drop is prevented.
When the growth and expansion stage of the fruit of the Or is 12 months to 5 months of the next year and the optimal growth period of 5-11 months with abundant rainwater illumination is partially missed, the sweetness of the fruit is difficult to reach the optimal quality by continuously using normal cultivation management, and artificial sweetening management measures are required. By carrying out special cultivation management measures 45-60 days before picking of fruit trees, organic nitrogen fertilizer and water-soluble organic fertilizer are mainly applied, so that organic nutrition is directly absorbed by trees; inhibiting the vegetative growth of fruit trees and leading nutrient substances to be intensively transferred to fruits so as to realize the sweetening of the fruits.
The invention has the advantages that: the invention leads the Or citrus to bloom in autumn of 9-10 months by the manual intervention of the steps S1-S3, and the normal flower and fruit period of the Or citrus is staggered; realizing flower and fruit retention through steps S4-S5 in the flower and fruit period; the sweetening operation of S7 ensures that the fruit can still reach normal sweetness though not in the normal fruiting period; the Or oranges are ripe and picked in 6-8 months of the next year, the peak staggering is carried out, the market selling is avoided, the fruit delay caused by over supply and over demand due to high fruit yield is avoided, and the economic income is improved.
