Stems glabrous; Leaves papery, glabrous on both sides; Stipules linear, lanceolate; The flowers are fragrant and white, the sepals are oblong, the petals are lanceolate, and the ovary is obovoid; The fruit is oval and the skin is hard. The flowering period is from April to June, and the fruiting period is from July to April of the following year. Because its fruit looks like an egg, it is called "egg fruit".
Passion fruit originated in the large and small Antilles and is now widely planted in tropical and subtropical regions. It is cultivated in China, Guangdong, Hainan, Fujian, Yunnan and Taiwan Province provinces. The soil that likes light, is rich in organic matter, loose in soil layer and well drained is better. Resist water accumulation and drought. Often born at an altitude of 180 ~ 1900 meters. The propagation mode of passion fruit is sowing propagation or cutting propagation.
Planting method of passion fruit
1. Land selection: Choose gentle slope land with deep and fertile soil, good drainage, convenient transportation and sunny and leeward.
2. Planting: when planting, straighten out the root system, fill the soil in layers and tamp it. Water the roots in time after planting. In the newly dug planting hole, the root neck of seedlings is slightly higher than the ground 8 ~ 10 cm when planting. After planting, sort out the tree tray and cover it with grass or film to keep warm and moist. The row spacing of planting holes is 4×5 meters, and 25 plants are planted per mu. The depth of the cave is 60×60×60 cm. Apply 25 kg of farmyard manure and 0.5 kg of phosphate fertilizer to each hole as base fertilizer.
3. Fertilization: The newly planted passion fruit is mainly nitrogen fertilizer in the early stage to promote plant growth. Rooting begins on 10 ~ 15 days after planting, and 0.5% diluted urea or diluted human excrement and urine can be applied, and then 5 kg of decomposed human excrement and urine or 0. 1 kg of compound fertilizer can be applied to each plant every 20 days.
20-30 kg of farm manure, 0.6-0.7 kg of urea, 0.6-0.9 kg of phosphate fertilizer and 0.2-/0.3 kg of potash fertilizer are applied to each fruit tree every year. Farmhouse manure and phosphate fertilizer were applied before and after beginning of spring, urea and potassium fertilizer were applied once a month during flowering and fruiting, and the mixed fertilizer was 0.3 ~ 0.4 kg per plant.
4, watering: Passion fruit is a shallow-rooted plant, like to be wet, both avoid water and fear of drought. Therefore, first of all, we should open the drainage ditch to prevent water accumulation in the orchard; At the same time, weeds should be paved to keep water, and irrigation should be considered once every 15 days without rain.
