Is the planting technology of star passion fruit not easy to set fruit? What are the color characteristics of star passion fruit

American hybrid varieties have strong resistance, do not choose soil, grow very fast, but have poor cold tolerance. Full-sky star passion fruit weight of about 150 grams per fruit, several times larger than ordinary varieties, honey passion, sweet but not sour, rich fruit flavor, is a dual-purpose variety for fresh sale and processing. Generally speaking, a single plant has a yield of 40-60 jin in the same year, and the yield per mu can reach 4000 jin.

The appearance of the star passion fruit is beautiful, the color is purplish red, but it has small white spots, which is like the little star, so it is called the star passion fruit.

The invention relates to a method for planting full-sky passion fruit, which is characterized in that it comprises the following steps:

(I) choose Mantian star passion fruit varieties with high sugar content

(2) adjust soil pH: adjust soil pH to 7.2-7.4 with lime.

(3) to establish the base of Baixiang Orchard: the scaffolding is built with water pipes, the height of the columns is 3 meters, and the fishing line is used to build the top of the scaffolding. There are at least I steel wire horizontal lines between every two water pipes, and there are several vertical steel wire vertical lines on the horizontal line. Each steel wire vertical line spacing is 30-50 cm, forming a side net.

(4) planting: using scaffolding cultivation, according to the specifications of row spacing 2-3 meters, plant spacing 2-3 meters, 80-90 plants / mu, the ridge trench is dug 70 cm wide, and the side of the planting ditch is provided with an auxiliary trench, the distance between the auxiliary ditch and the planting ditch is 5-LOCM, and there are several connecting holes between the auxiliary ditch and the planting ditch. After excavation, the fermented compost was filled in the auxiliary ditch, and 70 liters of fertilizer solution was added, and then the ripe soil was backfilled, and then the raw soil was backfilled; then the value of passion fruit was determined, and after planting, the seedling was drip irrigated with fermentation liquid.

(5) pruning: in March, after the seedlings are planted and survive, the buds should be removed at any time, leaving only the top buds of the main vines, and the vines should be tied to the pillars so that the plants can climb to the side net as soon as possible; when the plants between the two side nets are connected to block the sun, cut the plants at the top, leaving four side vines on each side and grow on both sides; when the side net is covered with plants, cut the side short, and spray fungicide at the short cut.

(6) flowering treatment: before flowering and fruiting, honeybee hives were set up at two side nets. After passion fruit blossomed, at 7 o'clock every day, the honey was dipped in the brush and daubed on the side net, and the flower dew was sprinkled to dilute it. From late June to early July, 150 times of potassium dihydrogen phosphate solution was sprayed, and fertilizer treatment was carried out. Three months of ternary compound fertilizer was used to replenish fertilizer, and then the side net was rusted. The fruit can then be picked.

(7) temperature control treatment: the temperature of the greenhouse was controlled at 30-36 ℃ to ensure the suitable temperature for the growth of passion fruit.

two。 The planting method of full-sky passion fruit according to claim 1 is characterized in that the compost described in step (4) is an organic fertilizer with a weight ratio of 47% pig manure + 20% nitrogen, phosphorus and potassium at 2:1:4, the rest is supplemented with water and fermented in a fermentor for 20 days.

3. The planting method of full-sky passion fruit according to claim 1 is characterized in that the side net is changed every two years.

4. The planting method of full-sky passion fruit according to claim 1 is characterized in that during the flowering treatment of step (6), honey is applied in the middle and top position of the side net.

5. The planting method of full-sky passion fruit according to claim 1 is characterized in that: in step (2), the top frame formed by the fishing line is a plurality of diamonds, and in step (7), the greenhouse is arranged on the top of the top frame formed by the fishing line.
