Death of sex of physiology of cucumber root system is to point to cucumber lateral root and Mao Xigen quantity to decrease apparently, root system xylem changes brown or decay. But the phenomenon that root system restores to still can give birth to a lateral root through period of time, cucumber root system dies in two obvious unripe reason inside whole birth cycle. Although root system attributes unripe rational death, but grow to have certain effect with cucumber crop to plant, the time that knows root system physiology dies accordingly paragraph, undertake raising root management next, can avoid appearance of reduction of output.
The time that root system physiology dies paragraph
1, death of sex of first time physiology is day of the 15~20 after blossomming when be being harvested to the first fructification.
This period, plant nutrient begins to grow to reproduction supply, because fructification held back partial nutrition, make root system incommensurate this kind of change, consequently plant lateral root and Mao Xigen produce a quantity to decrease somewhat, later period misgovern can bring about partial root system to change brown or decay.
2, the 2nd times unripe rational death is in about lumbar melon is picked in later period, when plant growth period amounts to 100 days or so, begin namely.
Plant course early days is exuberant result, begin to enter right now grow later period, root system begins to ebb gradually, root quantity decreases apparently, upside lamina color becomes shallow, stretchy speed decelerates bibcock, cauline slim and fragile, plant grows apparent slow down.
Run measure
The administrative measure that first time physiology dies
Root melon collects root of the hurried before closing to close to fry lets plant grow evenly; Root melon as soon as possible is picked, lest drop fry; Root melon is collected receive around to strengthen fat conduit to manage.
The administrative measure that the 2nd times physiology dies
The root system management of this phase appears particularly important, if misgovern, crop of serious effect later period, make uproot plants after their edible portions have been harvested of plant in advance. Following precautionary measures can adopt on production:
1, add apply organic fertilizer, improve granule composition of soil, the growth that is root system offers good condition.
2, adjust the relation that plant nutrition grows with reproduction, help advance somebody's career on this period can not let plant dropping big melon, melon blossom collect namely close, can undertake when necessary proper scanty melon.
3, strengthen plant nutrition and prevention and cure of plant diseases and insect pests, have top application of face of blade in time, nutrition of fast and compensatory plant. Top application of face of blade can undertake at the same time along with prevention and cure of plant diseases and insect pests, 7~10 day 1, wait for new root to happen in great quantities, turn into normal management gradually again.
4, gush is applied grow element, promote new root to be sent quickly, can use 600-800 of 0.1% agent of water of methyl a-naphthyl acetate times fluid sparge 1.
5, work with seeing on moisture management see wet advisable.
