How to do cucumber dead tree

The cucumber in the greenhouse is very dead, how to deal with it?

There are three main reasons for the death of cucumber: First, the excessive amount of watering at one time causes the ground temperature to drop, and the root oxygen demand is insufficient to produce roots, which is the main cause of dead cucumber. Secondly, excessive use of chemical fertilizers causes soil salinization, which causes cucumber to burn roots is another important reason for its dead trees. Some vegetable farmers saw the high price period in front of them. In order to promote the increase of cucumber yield, the amount of chemical fertilizer used was too large, resulting in root injury, which led to the death of cucumber. Again, the occurrence of P. sinensis root rot and blight also caused a large number of cucumbers to die.

For the above several situations, it is recommended that vegetable farmers:

Picking up the mulch on the side of the cucumber root, then weaving and wetting to enhance the permeability of the soil and promote the growth of the cucumber roots, so as to alleviate the roots produced by excessive watering, but be sure not to damage the roots when scribing .

For the dead roots caused by excessive fertilization, the vegetable farmers should reduce the amount of fertilizer used. In the future, it is best to use the water-agricultural knowledge to dissolve the fertilization, and use 6-10 kg per acre. For the Phytophthora root rot, the carbendazim 500-fold solution can be mixed with the hydrazine double-irrigation root or the carbendazim 4000 times solution mixed with the aliquot 5000 times liquid or the mixed shell-like abundance 300 times solution. The blight is sprayed or smeared with Ami's 1000 times solution.
