The management of grape seedlings in winter and spring has been relatively clear to fruit farmers, and the management of the summer and autumn fertilizers that are related to the growth of grapes is directly related to the benefits of grapes and should also attract attention.
Fertilization, two ways. The first is to top-dress fertilizers, and generally it is possible to recover urea. When the grape seedlings grow to 7-8 leaves, apply 15-20 urea every 666.7 minutes, and apply them 15-20 days before applying 1 time. Normally, it can be applied 3 times. The second is extra-root fertilizer. Spray 0.5% urea in summer and 0.3% potassium dihydrogen phosphate in autumn, spray twice.
Timely watering. Before the grape cuttings sprout, they are usually poured every 5-7 days. After the new shoot grows to 10-20cm, water is poured every half month. After the new shoots grow to 30-40 cm, water is poured every 20 days. If the weather is rainy and the sensation is better, do not water it. When the seedlings grow to 50cm, watering should be properly controlled. If the grape seedlings do not produce pods before the winter, they must be poured with overwintering water (such as the area where the winter needs to be buried, it is best to plant a garden to prevent freezing). Every time you topdress, you should water it.
Weeding and weeding. There are many mulch in nursery gardens, and cultivators are usually used to pick out weeds. On both sides and on both sides, it is necessary to remove the weeds at the same time after each watering. Http://
