First, Baohuabaoguo Apple Xiehua 3 to 4 days after flowering, once a flower, 7-10 days there is a physiological fruit drop, 20-30 days there was a second physiological fruit drop, the main reason for the occurrence of flowering and fruiting is poor pollination and fertilization. Nutritional competition. Therefore, appropriate measures should be taken to preserve the fruit.
1, artificial pollination, most of the varieties of apple self-pollination ability is poor, therefore, in the pollen tree misconfiguration, single species or poor flowering weather conditions, artificial assistant pollination. The specific method is as follows:
(1) To collect pollen, first select the appropriate pollination type. When the flowers of the pollinated variety are to be placed or placed, the flowers are taken from the tree and taken to the room for screening. The anthers are spread on paper, dried and dried for 1-2 days, and the pollen is hand-picked to remove the impurities. The pollen is bottled and put in a dry place.
(2) Pollination methods Generally, pollination is best when there are more than 25% of flowers opening in the early flowering period. Can be sprayed or sprayed.
1 point method: Mix the pollen with 3-5 times the talcum powder or starch. Mix it evenly and put it into a vial. Use a brush or a wire with an eraser to draw pollen from flower to flower.
2 powder spray method: the apple pollen added 10-50 times the talcum powder or starch, mixed uniformly, with a duster to flower
Sprinkle, but avoid windy weather.
3 spray method: The pollen and sucrose, borax, etc. into a suspension of aqueous solution, with ultra low sprayer pollination. The preparation method is as follows: 10 grams of dried pollen, 250 grams of sucrose, 15 grams of urea, 5 grams of borax, and 5 kilograms of water after mixing. After mixing, filter the impurities with two or three layers of gauze. Spray it immediately after it is ready for use, and use with it. Do not leave it for more than two hours.
4 towel bar pollination: at the tip of a long string tied a towel tube containing wheat straw, made of towel bars. When pollinating, the pollinated tree begins to roll on the inflorescence that begins to loosen, and is covered with pollen before it is rolled on the flowering inflorescence of the tree to be pollinated.
2. Put bee pollination: 1.5 boxes of bees or 750 bees are placed on each hectare and placed in the middle of the apple orchard 2-3 days before flowering.
3. Foliar spraying and spraying spraying 0.3% borax solution during flowering, spraying 0.5% urea aqueous solution before flowering, all have the effect of increasing fruit setting rate.
4, fruit bagging bags to prevent pest damage, so that the fruit surface smooth, clean, good coloring. Yellow and white single-layer bags are used for yellow and green varieties. Red varieties are available in single-layer fruit bags and double-layer fruit bags. The single-layer fruit bag is a gray or yellow-white outside and the inner black bag; the double-fruit bag is the outside of the bag is gray or yellow-white outside, the inside is black, the inner bag is red or green wax paper and the outer bag yellow white, inner bag Black double paper bag. Yellow-green varieties that are susceptible to fruit rust will be bagged within 20 days after flowering. The red variety is set after bagging. The yellow and green varieties are collected together with the fruit bags when they are harvested, and then removed when they are packed. Bags should be taken after 4:00 pm or on cloudy days. Gradually, they should be gradually removed to prevent the tender skin from seeing sunburn. For red varieties using a single-layer bag, the bag is torn into an umbrella shape 20-40 days before harvesting. The cover is placed on the fruit to prevent direct sunlight and the bag is removed after 7-10 days. For red varieties using the inner wax double bag, remove the outer bag about 25 days before picking, leaving the inner bag, and remove the inner bag after 5-7 days. For red varieties using outer yellow white and black double bags, the bottom of the outer bag shall be torn off approximately 25 days prior to harvesting. The inner lining shall be removed and the bottom of the outer bag shall be opened. After 5-7 days, the outer bag shall be removed. .
Second, when the fruit is too thin and too thin, it is not only of small quality, but also consumes too much nutrients, which affects flowering, and reduces the annual output of the next year. In order to realize high-quality, stable production, control, and overcoming the phenomena of size and size, it is necessary to carry out fruit thinning and fruit thinning.
(1) Artificially sparse and thinning fruit
1 Thinning flowers: Thinning can be carried out from flower buds to flowering stages. The best period is the inflorescence separation period. The specific method is to leave an inflorescence at a certain distance according to the characteristics of varieties, flower size, strength and weakness of the tree potential. Generally, large fruit is farther, such as Fujifilm needs to be separated by 20-25 centimeters, small fruits can be closer, such as Chiaki Interval 15-20 centimeters; tree vigor is more prosperous and weaker may be more. In the remaining inflorescences, depending on the specific conditions of the locality, the amount of flowers to be retained can be determined. The land that is prone to frost damage can leave more of this flower. The warm-protected plots can leave fewer flowers; generally, the large fruit leaves 2-3 flowers, small Leave 3-4 flowers; fruit settling to retain 2-3 flowers, set aside low rate of 3-4 flowers. Such as the new red star and other marshals are short-stem type, although it is a large fruit, but its fruit set rate is low, can leave 3-4 flowers per inflorescence, sparse flowers, as far as possible to protect the center of the flower, remove the edge of flowers.
2 fruit thinning: 10-20 days after flowering, young fruit room expansion period, sparse dense fruit and too weak fruit, set the fruit. There are many ways to fix fruit. One is the simple and easy method of equidistant fruit retention, that is, to keep 1-2 fruits at certain distances according to fruit type, variety, and tree vigor. Generally, small fruit varieties leave 1-2 fruits every 15-20 centimeters, and the tree vigor is more prosperous. The tree vigor is farther weaker. The fruit and the auxiliary shoots are strong and stay strong, leaving weak fruits. For large fruit, leave one fruit every 20-25 cm and leave it alone. When thinning fruit, it is necessary to go to the deformed fruit, disease and fruit and small fruit, and then go to the weak fruit to retain the center fruit. In addition, the fruits on the fruiting branches and the fruits in the sagging direction are generally large, fruit positive, and fruit shape index high, and they should be retained as much as possible. Another method of fixing fruit is to look at the side shoots and set the fruit, that is, there is a large fruit in the secondary shoot of the strong fruit, and the single fruit in the small fruit, the double fruit in the small fruit, the single fruit in the middle secondary shoot, and the double fruit in the small fruit. The large fruit of the short side shoots does not leave fruit, the small fruit leaves the single fruit, and there is no remaining fruit on the side shoots.
Third, improve fruit quality
(1) Bagging: The consequences of the bagging are clean and smooth, no traces of rust, good coloring, beautiful appearance and high commodity value. In addition, pests can also be prevented from being harmed.
(2) Picking leaves and transforming fruit: After bagging fruit to bag, in order to promote fruit coloring, shade leaves and fruit leaves around the fruit must be removed in time so that more than 60% of the fruit surface is exposed to direct light. When the leaves are removed, some petioles are retained, and the amount of leaves removed is controlled to be less than 30% of the total leaf volume. And turn the fruit once every 7-10 days to make it fully colored.
(3) Laying of reflective film: One month before fruit ripening, silver-gray reflective film is laid along the outer edge of the crown along the tree line, which can increase the intensity of scattered light in the orchard and promote good coloring of the fruit.
(4) Harvesting: According to different needs, when the fruit reaches the corresponding optimal maturity, it will be harvested. If it is too early or too late, it will affect the quality of the fruit. When the fruit reaches the inherent color and flavor of the variety, it is suitable for harvesting. When picking the fruit, special tools are used to cut the stem in the stem and gently handle it; ensure that the fruit is not damaged; when fruit is harvested, proceed in the order of first crown, rear crown, first lower layer, and upper layer.
