1. Cultivation techniques and site selection of passion fruit 1
Passion fruit is a tropical and subtropical fruit. When planting, the planting place should not be too high, and it is better to be below 1200 density. The field should be flat and planted with holes. Can be planted on the slope to make a horizontal ladder. Before planting, the surface width should be greater than 1 m, and the inner wall should be smooth with an inclination of 5 degrees. The soil should be fertile, loose, well drained and deep; The whole environment should have enough light.
Step 2 plant
Passion fruit can be planted and grown all year round as long as the temperature is suitable, and the best planting time is in spring and autumn. The number and scale of planting should be determined according to the area of scaffolding. If the scaffold is 5 meters long and 6 meters wide, the number of plants planted is about 20; If the hedge frame is 3 meters long and 3 meters wide, the number of plants is about 70, and the spacing is about 50 cm. Dig the pit and put in the base fertilizer, put in about 5 ~ 10 kg of poultry manure and 0.5 kg of calcium magnesium phosphate fertilizer, then put in plants to cover the soil and water it, and cover the soil with straw to keep it moist.
3. Scaffolding
? Passion fruit is a vine with strong branching ability. When it grows to a certain time, it will have a dense crown and slender branches, and the length of the base can reach 10 meter. Stem, leaf and base are interdependent, criss-crossing and impenetrable. So scaffolding is needed. Passion fruit can be built according to your own preferences and the size of the place, such as horizontal scaffolding, inclined scaffolding, A scaffolding and so on. , height control in 1.5 ~ 2 meters, suitable for picking, erection materials can be obtained locally.
After erecting, use a small bamboo pole to lead the tip of the main vine up and slowly put it on the scaffold. After being placed on the frame, the space is relatively large. Each plant keeps 2 ~ 3 main branches and extends in different directions. At the same time, the lateral buds on the main branches are removed to promote the growth of lateral vines. In the future management, the principle is to prune frequently to keep the plants ventilated.
Second, the management technology of passion fruit 1, fertilization
As mentioned in the above passion fruit cultivation and management techniques, passion fruit likes fertile soil, so base fertilizer should be put when planting and fertilization should be applied in daily management. Before the newly planted passion fruit bears fruit, it is mainly nitrogen fertilizer, which is applied once a month to promote plant growth.
Mature passion fruit should be fertilized in February-March, mainly with farmyard manure and a small amount of phosphate fertilizer. Fertilization should be buried. Dig a 20 cm ditch around the root 1 m, mix the fertilizer with soil, and cover the soil with clear water. During the fruit growth period from April to May, the second flowering period after picking in August to September, and the fruit growth period from June 5438+00 to June 5438+0 1.2, the nitrogen and potassium compound fertilizer should be added once. This time, the fertilizer is mainly liquid fertilizer, which can be sprayed at a distance of 0.8 ~ 1.2 meters from the roots of plants.
Step 2: Moisture
Passion fruit is sensitive to water, afraid of both drought and waterlogging, and belongs to shallow-rooted plants. In daily management, special attention should be paid to watering and drainage. Once passion fruit is short of water, its stems will become thinner, its leaves will turn yellow, its flowers will become smaller, and the number of nodes will decrease, which will lead to a series of adverse reactions, the most important of which will affect the yield. However, if there is too much water, it will accumulate water and the roots of plants will rot. Therefore, attention should be paid to drainage when breeding, and the soil should be kept moist while watering.
3. Tian Tuan management
Summer and autumn are the most vigorous seasons for passion fruit growth. Generally, shallow hoeing should be done to the soil after rain. When there are many weeds, weeding should be carried out, and the depth can be 5 ~ 10 cm. Intertillage is very beneficial to the growth of plants, which can loosen the soil, promote the decomposition of nutrients and the activity of microorganisms, and maintain the balance between soil fertility and water.
After the fruits are picked and cleaned in winter, the whole garden should be turned over, and the weeds and litter in the garden should be turned into the soil to rot the fertilizer. At the same time, 0.8 ~ 1.2 kg lime powder should be applied to each passion fruit, mainly to dig out hibernating pests, so that eggs have nowhere to hide in the sun and reduce pests and diseases in the next year.
prune
Passion fruit pruning is divided into big scissors and small scissors. Large pruning is usually carried out in the middle and late February. At this time, passion fruit is in the hibernation season, so you can remove some dead branches and leaves, cut off the main branches 50 cm long, cut off the side branches and branches wrapped around the shed. Small pruning is to prune the branches, twigs and diseased branches that have already borne fruit after each fruit picking. This is a budding bud with concentrated supply of nutrients to promote its growth and fruiting.
5. Prevention of pests and diseases
Passion fruit is vulnerable to basic rot, virus disease, epidemic disease, leaf blight, fruit borer and other pests. In the usual maintenance, we should pay attention to the supply of nutrients and water to enhance resistance. In addition, pruning should be done to keep the plants ventilated and transparent, and drainage should be done to prevent root rot. Pests and diseases of passion fruit are mainly prevented. Once there are pests and diseases, prescribe the right medicine and spray it in time.
Third, the effect of passion fruit 1 can improve immunity.
