Answer 1. Plant characteristics: the tree is flat, the branches are stout, the leaves are needle-shaped, the color is dark green, the length is about 14.3 cm, the width is about 6.9 cm, the corolla is rose-shaped, the color is pure white, the flower organs are developed, and the petals are large and thick. 2. Fruit characteristics: thick red skin, light yellow background, bright and shiny flesh, crisp and hard, purple color, edible rate of 96. 1%, average single fruit weight of 9.4g, the larger one can reach13g. 3. Planting points: When planting in protected areas, the greenhouse can be raised in advance to speed up fruit ripening.

I. Plant characteristics

1, the tree is spreading, with thick branches, yellow-gray annual branches and yellow-brown perennial branches.

2. The new shoots are yellow-red, the leaves are dark green (large, thick and smooth), the shape is lanceolate, the length is about 14.3 cm, the width is about 6.9 cm, and the aspect ratio is 2.07.

3. Petiole is green and red, about 2.9 cm long. The corolla is pure white, rose-shaped, with well-developed flower organs and large and thick petals.

4. When planted in Tai 'an, Shandong Province, the buds begin to swell around March 23rd every year, reaching full bloom around April 9th, and the fruits begin to mature around May18th. The ripening period is 39 days later than that of red cherry (the harvesting period is 3 days shorter than that of red cherry), 6 days later than that of early big cherry and 4 days earlier than that of early cherry.

Second, the characteristics of fruit

1, the fruit stalk is short and thick, with an average length of 3. 1 cm, which is similar to red cherry and belongs to short stalk variety.

2, the peel is thick red, the background color is light yellow, and the oil is bright and shiny. The top of the fruit is flat or slightly concave, with an average fruit weight of 9.4 grams, and the larger fruit can reach 13 grams.

3. The pulp is crisp and hard, and the total hardness (including skin) 199.7 g/mm2 is 2.3 times that of red cherry.

4. The flesh is purplish red, with small benevolence, edible rate of 96. 1% and sugar content of 17%, which is 60% higher than that of red cherry on average.

5. The acid content of pulp is 0.97%, which is 28% lower than that of red cherry on average. The ratio of sugar to acid is 17.5, which is 2.2 times that of red cherry.

Third, the main points of planting

1, and the refrigeration capacity of this plant is 680 hours. If plants are planted in protected areas, the temperature can be raised in advance and the fruit ripening time can be accelerated.

2. When cultivated in the open field, this variety ripens 3 days later than red cherry. If cultivated in the same shed in the protected area, it ripens at the same time as the red cherry.

In April, the leaf spreading time is about 1 1, the defoliation time is about165438+1late October, and the vegetative growth period is about 220 days/year.
