Abstract
The invention provides a crop pruning method, in particular to a pruning method which can improve the yield per unit area of the rape vegetable flower. The method of the invention is that in March to April, when the florescence of the rape is just over, the young (silique) fruit on the lower end of the anthotaxy comes into being preliminarily, and half of the flowers on the upside of the anthotaxy still do not fade, the technology measurement of pruning (or extirpating) the tip end of the anthotaxy can be conducted to prevent the anthotaxy of the rape from keeping on growing higher and consuming the moisture nourishment, and promote the footstalk on the lower end of the cutting opening to grow thicker, as well as the silique bigger and the purpose of production increase can be achieved with obvious economic benefit.
Description
Technical field
The present invention is the trimming method of a kind of crops, especially a kind of rape of increasing the yield per unit area (Brassica napus L.) flower thinning pruning method.
Background technology
Pruning is widely used in the production of fruit trees, usually in plantation and brephic, carries out doing surely shaping, and plant is trimmed to definite shape.As the natural open centre shape of peach, the evacuation layering shape of pear tree etc.Need cut off sick branch, water sprout etc. simultaneously.Its key link is to make tree crown be subjected to the light abundance, and the fruit growth stalwartness reaches the high yield purpose.
Pruning technique also is applied to economic forest such as tealeaves and Folium llicis Latifoliae.
Sesame and soybean pinching are the tapers of plucking trunk or branch.
Rape is plucked main tongue, also is a kind of pruning form.The tender flower stalk of rape can eat, and plucks once main tongue, can not influence rape seed output.
The all timberlands and the ecological forest, more extensive in management, only training is not pruned traditionally.Application for a patent for invention number 03116395.5 genus Folium llicis Latifoliae blade is pruned.Application for a patent for invention numbers 200410018269.9 and 20041008274.X then are to the bud picking of Folium llicis Latifoliae nursery stock, top clipping and cut a dry finishing and cut.Application number 200510061442 is sprout trimming methods of pine genus tree.
On production of fruit trees, flower and fruit thinning is an important well stimulation.According to the general requirement of flower and fruit thinning three-step approach (promptly flower thinning preface, in time dredge fixed late fruit of young fruit, optimum period) early and flower and fruit thinning, stay on the position really at needs and to stay complete inflorescence, the inflorescence that does not need to bear fruit all removes.Simultaneously, the flower thinning of some fruit tree requires to carry out in flower bud phase or inflorescence separation period, dredges and removes Xiao Hua, weak flower and time flower.As seen the fruit tree flower thinning methods that remove inflorescence that adopt are perhaps dredged from inflorescence and are gone to spend and time flower a little less than the Xiao Hua more.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition be at rape in the process of yielding positive results, inflorescence first half subangle (pod) fruit progressively dwindles, invalid angle (pod) fruit is increased gradually, influence the problem of rape seed output, a kind of rape flower thinning pruning method is provided, to stop the invalid growth in inflorescence top and to the consumption of moisture nutriment, promote bennet chap, angle (pod) fruit to increase and well-balanced, reach the purpose of remarkable volume increase.For this reason, the present invention is by the following technical solutions:
Rape flower thinning pruning method is characterized in that withering and having 1/2 flower to form the inflorescence top tip that begins to extract rape in the fruit of little angle in brassica napus inflorescence Lower Half flower in 3～April, and the length of extracing the inflorescence top tip is 0.5cm～2cm.
Divide the excision of finishing the brassica napus inflorescence top tip for 2～3 times.
Rape was not done the flower thinning pruning in the past, and there is the custom of plucking main tongue in some places, and it is edible to aim to provide vegetables, was that the mixed branch before not blooming is pruned, and was not to be the flower thinning pruning.Rape flower thinning is pruned, obviously be different from the pruning of economy of the fruit tree woods and timber forest, also be different from sesame and soybean pinching: the rape flower thinning plant for pruning is an inflorescence, general trees pruning fruit tree object mostly is vegetative shoot or mixed branch, and sesame and soybean pinching, what prune is trunk or branch taper, is not to be inflorescence.The flower thinning of rape more is different from the flower thinning of fruit tree: what the former cut off is an inflorescence part (top end), and what the latter removed is whole inflorescence, perhaps weak flower, Xiao Hua and inferior flower.Rape flower thinning is pruned, be flower thinning be again to prune, both have concurrently, are flower thinnings and prune purpose, prune so be referred to as flower thinning.The trimming method of this character also is the unprecedented trimming method of other plant.
The present invention--rape flower thinning pruning method has following advantage:
1, reducing brassica napus inflorescence top nutrient water consumes;
2, make the siliqua of oilseed rape size evenly, seed is full;
3, rape seed yield per unit area improves 12～23%;
4, easy and simple to handle easy, cost is lower.
The increasing yield that rape flower thinning is pruned: brassica napus inflorescence is a raceme, also belongs to indefinite inflorescence, and these inflorescence characteristics are that inflorescence bottom flower is opened earlier, open behind the flower of top, and its open hour are more and more slow from top to bottom; Flower withers and time as a result, also be the bottom early, top is slow.When inflorescence Lower Half flower wither, when bearing young fruit, the first half flower is but still in opening, so that also be in bud stage.Along with the constantly upwards growth of rape raceme, to consume plant large quantity of moisture nutriment on the one hand; On the other hand, because the upper end flower is more and more long from the distance of soil and greenery layer, the organic and inorganic nutrients that can supply also reduce gradually.Therefore behind the brassica napus inflorescence result, its fruit (angle fruit) also is more and more little from top to bottom, prunes and brassica napus inflorescence is implemented top end, then can stop the invalid growth in top, reduces nutrient consumption, makes the chap thereupon of clip below bennet, and the angle fruit has also obviously increased.Simultaneously, after enforcement inflorescence taper is pruned, lose the apical growth advantage, can also promote plant bottom flower and angle really to grow owing to be distributed in rape plant top inflorescence.So the yield per unit area of rape seed can significantly increase.
