How to manage the coloring period of Crisson grape?

We all know that Crisson grape is a very late ripening species, because after mid-late September, the sun exposure and temperature have plummeted, the leaves are also brittle seriously, want to leave new buds, but also afraid of frost and mildew, the overall plant photosynthesis and nutrient absorption profits are greatly affected, so coloring is a huge problem, today Huinong network editor is talking about the implementation plan of Crisen red color period management!

Since the perfect stage of the Crisson grape is after mid-late September, the coloring of the Crisson grape must be carried out early, and the end of July is the first step.

At the end of July, we should first stop all diseases and insect pests and add Bordeaux liquid.

The second step is to get rid of unnecessary shoots, whether the top or fork, to prevent the feeling of frost and mildew again after standing in autumn.

Third, stick close to the third thin wire (the area available to female workers) to leave a new tip, stay outside, so that he stretches horizontally, waiting for the standing autumn to enhance the sunlight and promote the application of coloring.

Fourth, if the fruit is not big enough, it must be irrigated at dusk in the near future to magnify the temperature difference to promote the fruit to rise.

Fifth, the integration of weeding, proper tiller loose *, not afraid of breaking the outer bark rhizome, (control soil temperature to increase air permeability).

Cold Dew is a demarcation point in August.

first。 After standing, the new shoots buried after autumn should be removed from the top, leaving at least 3 leaves, regardless of size.

Second。 7After 10 days (depending on the size of the fruit), the new shoots were sprayed with nutritional colorant.

Third。 The integration of pest control, all spraying microbial agents in the garden.

Fourth. In the first and middle of August, 30 jin of low-nitrogen and high-potassium water-soluble fertilizer or 1: 1 ratio of potassium dihydrogen and potassium nitrate were applied per mu (15 jin each). It is the amount of irrigation, and the amount of seepage irrigation is moderately increased.

At the beginning of September, the foundation is set around the teacher's Day, small strings and loose strings will be the first to be colored, the loose strings have no bore fruit, the color foundation is normal, the second tight string, the big string must be further diligent.

first。 All the branches are broken and the grandchildren are topped off, regardless of size. (I have already felt seven downy mildew, except for those with insufficient leaf area.)

Second。 At the end of August and the beginning of November (depending on the size of the string), the new shoots were sprayed with nutritional colorant for the second time.

Third。 With the integration of pest control, microbial agents were sprayed again in the garden.

Fourth. At the beginning of September, 15 jin of high-quality and high-potassium water-soluble fertilizer was applied to 1 mu. It is the amount of irrigation, and the amount of seepage irrigation is moderately increased.

Fifth. Soil layer tiller, control soil temperature. Around the National Day, some fruit shape is poor, the production is too high, the string type is too large, poor management methods are still uncolored, it is only required to take off the bag coloring and hormone drug colorants.

If it is not very serious, the lower hole of the bag is breathable, and it is not necessary to take off the bag as much as possible, so that the Crisson grape can be colored successfully. The net editor proposes that the implementation plan of the color period management method is expected to be studied by the growers. After all, it is now a good-looking social development, and the network editor believes that the beautiful color of your Krisson grapes will greatly increase your sales!
