Selection of 1. Pot: Generally, grapes are cultivated with a diameter of 1.0 feet to 1.2 feet. 65438+ 0-2 years after planting, pour into a larger pot. Under the condition of ensuring that the roots are not scattered, cut off some dead roots and over-dense roots, put them into a new basin to fill the soil, and pour them into the water. Then irrigate the basin 1 time every 3-4 years, and properly drain and cut the roots to keep the grapes growing vigorously. ?
2. Pot soil preparation: select 2/3 of decomposed horse manure, sheep manure1/mixed nutrient soil and pastoral soil (or aeolian soil), put in pots, pour thoroughly, and plant after the surface is dry and loose. ?
3. Planting time: you can choose 1-2-year-old grafted seedlings or cuttings with roots, which can be planted in February-March every year (the seedlings with roots in nutrient pots can be planted in February-April to early May-June every year). ?
4. Choose varieties suitable for potted plants: you can choose early-maturing and middle-maturing grape varieties with good quality and beautiful tree shape (early-maturing varieties can be cultivated twice, that is, twice a year), such as Zaoyan, Meirenzhi, Kangtai, Saba Pearl, etc., and middle-maturing varieties: rose fragrance, white banana, red perfume, Jing Ya, Jingxiu, etc. ?
5. Potted grapes must be placed on a sunny balcony: room temperature is above 10℃ to germinate and grow, the time temperature is not lower than 5℃, the flowering period is 25-28℃, the berry expansion period is kept at 28-32℃, and the humidity of the pot soil is kept at about 70%. ?
6. Water and fertilizer management: water for 3-4 days in early spring germination period 1 time; Water every 2-3 days from June to July 1 time; During the dormant period of 65438+February, water was poured with enough water 1-2 times. During germination, flowering and fruit setting, it is especially necessary to pour sheep manure 1 time on the leaves, spray ammonia, phosphorus and potassium fertilizer 1 time, and spray zinc fertilizer 1 time on the leaves before and after flowering. ?
7. Keep the vines and set the branches: 1-2 The extended vines can be reserved for the grapes planted in the current year. Grapes can have 3-4 vines extending for many years, and each vine has 1 fruiting branch every 3-4 years. There are 3-4 leaves above the ear of the fruit, and 3-4 leaves above the ear of the fruit (reserved for bearing branches in the coming year). Extend the vine to about 1 m for coring, and the secondary branch will grow 1-2 leaves for coring, except for the extended vine. If the secondary fruit is promoted, the winter buds can be forced to germinate ahead of time and not produce leaves. ?
8. Shelving and binding: When the grapes are spreading and creeping in spring, insert three bamboo poles or wooden sticks with a length of about 1.3 m into the basin in a triangle shape, and tie the tops together with ropes to fix them. Then, with the growth of vines on the main side of the grapes, they are spirally or upward bound along a tripod (called a golden dragon plate and jade column frame), and attention should be paid to keeping a certain distance between vines so that each ear is exposed. In addition, you can also pull the rope to the roof of the shed on the balcony or take the room out of the balcony window. ?
9. Ear adjustment and yield adjustment: adjust the ear in time before flowering, and leave 1 ear for each bearing branch, and remove the rest. A pot with a diameter of 1- 1.2 feet can carry 3-5 Jin of fruit in 2-3 years. After 4 years, a pot can hold 10-20 Jin of fruit, and the larger the pot, the higher the yield will be. ?
