How to strengthen the management of the flowering period of grape planted in greenhouse
1. Pick your heart at the right time. The grapes planted in the shed should be reshaped by hedgerows, and the hearts should be picked early to control the growth. When the main vine grows to 60ml 80cm, the top accessory shoots are removed to leave winter buds, and the other secondary shoots are left with one leaf to pick the heart. 25 days later, when the apical winter buds germinated and grew 6 Mel 7 leaves, 5 leaves were left to pick the heart, and the apical accessory shoots were removed and the winter buds were left again.

How to manage newly planted grapevines
If the grapes planted in that year want to have early fruit and high yield, we should pay attention to the following measures in cultivation management: fertilization should be applied frequently and thinly in the growing season of grapes, so as to reduce fertilizer damage and waste, so as to promote the good growth and development of new shoots and lay a solid foundation for early formation, early fruiting and high yield.

Good flower and fruit thinning, high grape yield
First, we should pay attention to strengthening the management of fertilizer and water; second, we should leave the damaged leaves for a long time. It will take about a month to grow new lateral branches. The leaves of new lateral branches can replace diseased leaves for photosynthesis and alleviate drug damage. The grape should be observed in the orchard at any time after spraying, and abnormal pieces and plants are found.

The best time, purpose and method of thinning inflorescence of grape
The inflorescence pinched grape has many inflorescences, which is easy to consume a lot of nutrients and reduce the fruit setting rate. Pinching off the inflorescence tip can reduce the number of flowers, reduce the competition for nutrients and increase the fruit setting rate. The pinching time should be one week before flowering, and it should end when it comes to flowering. First, pinch off the accessory ear, then pinch off the supporting shaft on the main shaft, and leave 5.

Attention should be paid to potassium application in the middle and later stage of grape growth.
Potash fertilizer is very important during the whole growth period of grapes, especially during fruit growth. Therefore, the grape is called "potassium" quality crop. Potash fertilizer can promote grape fruit hypertrophy and ripening, improve variety and storage tolerance, promote branch thickening growth and ripening, and improve cold resistance, drought resistance and high tolerance.

Kiwifruit is busy clearing the garden in spring.
First, early prevention of diseases and insect pests: before germination and germination, 100 to 150 times more barium sulfide is used for tree pest control or stone-sulfur mixture of 3 to 5 degrees to kill eggs and overwintering bacteria. After leaf spreading, foliar fertilizer Nongkang 120 was sprayed to supplement fertilizer and prevent disease. Second, early application of budding fertilizer: the result is that each tree is compound.

Beware of freezing injury of kiwifruit in spring
In recent years, the phenomenon of "cold in late spring" is very prominent. the freezing injury in spring is one of the disastrous weather resulting in less sprouting, poor pollination, low fruit setting rate, postponement of growth period, high yield and income increase of kiwifruit. Preventing kiwifruit frost injury in spring is an important link in kiwifruit spring management work. Recently, the reporter went to Shaanxi.
