Corn tillering is overmuch, namely the long bifurcation that common weighs child, mean the contention of resource of illumination, moisture, nutrient, that corn bifurcation child answer to should be not broken?
And is as similar as this one phenomenon corn of one individual plant writtened guarantee more a few club answer to should be not broken?
And the surplus coping male the ear of grain in corn field answer to should be not broken?
One, corn bifurcation child should not break
Tell everybody, need not break, this old bifurcation child the biggest effect is replaced namely advocate the bine withholds nutrient, when advocate when cauline nutrient is insufficient, bifurcation child go to nutrient circumfluence again advocate bine, bifurcation child also with respect to wither, what so you break is not bifurcation child, be threw away nutrient.
Corn bifurcation child the advantage that does not break has as follows at 5 o'clock:
1, the foliaceous area that raises corn whole.
Consider to make clear: Do not go the foliaceous area of every hectare is the experimental corn breed of tillering 35610-46510 square metre, and go the area of every hectare leaf of tillering is 24690 square metre only, former get greatly than latter leaf area much, for corn generation more dry matter laid good foundation.
2, increased root coefficient. To root system determine to make clear as a result, leave evil average number of root of every individual plant is 56, and go evil individual plant is 29, increase 27.6 on average, increase namely 95% .
3, reduced what edaphic water divides to evaporate. Determine leave evil than going evil the earth's surface is in edaphic water content 10 centimeters tall 14.49% , what bigger foliaceous coronal layer reduced edaphic moisture is form to evaporate after leaving evil, the action that holds edaphic moisture reached since. Fall in this kind of circumstance it is thus clear that, blade rising and the earth's surface evaporate to be compared, evaporating effect is bigger, reason leaves evil to be able to maintain edaphic water portion and counteractive drought.
4, cut except top dominant position. Always bifurcation child much corn advocate it is short on cauline configuration thick fat, bifurcation child more, advocate the possibility with cauline long flourishing is less. Plant is short the mark that thick fat ability is high yield!
5, the circumfluence of reproductive element. Bifurcation child meet after corn takes hero gradually wither dies, among them moisture, light combines element of child, reproduction meeting circumfluence arrives advocate bine, for corn maturity offers nutrient finally.
(3) break bifurcation child disadvantage is broken except bifurcation child a kind of harm that is pair of plant, in the process of plant ego rehabilitate, plant diseases and insect pests inbreaks, the odds that fungus affects can be increased.
2, the club of much knot answer to should be not broken? Should!
Institute of corn of special type of Shenyang agriculture college teachs Shi Zhensheng to say, although general corn can written guarantee two clubs are controlled, but it is normal that this kinds of many marvellous corn also is belonged to. Have a few special corn variety, have much more marvellous characteristic. In addition, still concern with the environment, if nutrition and illumination are very sufficient, knot good amount is met somewhat grow in quantity. But in these corn clubs, probably only 3 two clubs above can blossom.
Majority of cross corn breed is breed of odd fruit spic, outside eliminating spike of plant upside fruit, the 2nd, growth of spic of the 3rd fruit is slow, spin is later, cannot be fertilized is strong, need to use up many nutrient however, excise nutrient of collect of invalid fruit spic to furnish advocate spic, can make advocate Sui Guosui increases, can increase bead to weigh not only, improve corn quality, still can promote precocity.
3, coping male spic answer to should be not broken? Should! Cultivate in corn in, also corn otherwise wants the doubt of emasculate, and in corn in cultivating, some farmer can give corn emasculate, but why does corn want emasculate? What does corn castration cut very method to have?
Mechanism of 1. increase production is clear.
After passing emasculate, can make plant is absorbed with production effective nutrient in a steady stream ceaseless Xiang Zili is carried, because breath uses up a large number of nutrient,reduced male spic thereby, achieve reduce the beautiful and disloyal, goal that raises to bead is weighed and raise per unit area yield.
2. plant becomes short, advantageous increase density.
Compare after emasculate not emasculate corn reduces high 25-30 centimeter, improved field and ventilated pervious to light condition, be helpful for increasing cultivate density, achieve with close increase production.
3. florescence has encountered, strong rate rises.
After emasculate, because improved plant zoology condition and nutrient to carry heading, than not day of 2-3 of reel off raw silk from cocoons of in advance of emasculate corn female spic, florescence encountering is good, pollination is enough, overcome a flower effectively and disloyal. Reduce empty lever to lead 3-5% at the same time, in advance becomes ripe 3-5 day.
4. reduces harm of snout moth's larva.
Corn snout moth's larva often gathers inside big horn mouth to take feed, gnaw the spic that feed hero first, reduce pollen to make an amount, it is to lay eggs next, the incomplete after hatch feeds other place. After passing emasculate, can unplug the pest together, take the processing outside cropland, reduced move to endanger machine rate thereby.
5. sends work little, cost is low.
Emasculate goes easily simply, men and women all can be operated, general castration 2-3 second, every mus use worker worker only 1 or so.
The time of emasculate did not come loose with taking hero it is advisable to undertake before pink, premature and easy injury 1, 2 tops leaf, already came loose too late pink, reduce emasculate effect.
Emasculate appropriate is in sunshine 10 - 15 when undertake, benefit cicatrizations at cut, prevent bacteria infection.
Overcast and rainy is continuous weather is unfavorable emasculate. Emasculate can be lain between go or lie between individual plant, go staying infirmly strong, emasculate is unfavorable 1/3 what exceed number of total individual plant.
Country, sloping field or with the wind two of the face unfavorable castration.
