Abstract
The invention discloses a root separation method for in-situ research of interspecific rhizosphere effect of field relay intercropping systems. The root separation method includes the steps of firstly, using a digging tool to longitudinally dig a furrow 5cm wide between two types of crops, which is half on the way of row spacing, digging at a certain depth in a 10cm soil layer each time to form the furrows, and placing the soil of each dug layer on two sides of each furrow; secondly, placing root separating material in the furrows, and tightly attaching the root separating material to one side wall of each furrow; and thirdly, backfilling the soil of each dug layer in the step 1 according to layering of original soil. The digging tool is used to dig the narrow furrows 5cm in width, and accordingly digging soil quantity and changing of each plough layer are reduced as compared with those in original digging of 40-50 cm wide furrows by a spade. Affection on crop growth caused by the fact that the backfilled soil layers are easy to settle in irrigating or raining and crops are easy to fall is avoided. In addition, 10cm digging layer by layer is adopted for furrow digging, and accordingly the original plough layer is guaranteed as far as possible, underground interspecific rhizosphere effect in relay intercropping systems can be researched more directly and accurately, and affection of research results in root separation process is avoided.

The method of the contribution of intercropping advantage being used always at research intercropping and interplanting ground, underground interspecies effect is root system separation method (at a distance from method for root); Study effect on the ground to the contribution of intercropping advantage through eliminating underground interspecies effect (plastic foil separation) fully, not exclusively eliminate a rhizosphere effect of sowing (separation of 30um nylon wire) study its contribution to the intercropping advantage.
But present separated method for root adopts " wide fluting " method, promptly between two kinds of Different Crop, opens the wide dell groove of 40～50cm with spade, in the groove of hole, places at a distance from the root timber material, and then with the soil that digs out backfill again, the realization root system is separated.Because the width of hole groove is bigger; It is big in digging process, to destroy the topsoil structural volume, has changed plant growth topsoil structure, after the soil layer backfill; Be prone to when irrigation or rainfall sink; Crop is prone to, and influences plant growth, sows that a rhizosphere effect effect causes or the topsoil structural change causes with being difficult to distinguish its intercropping advantage and being; Also there is tedious problem in addition.
Summary of the invention
The purpose of this invention is to provide a kind of " the separated root of rhizosphere effect between the intercropping and interplanting system kind of original position research land for growing field crops " method that reduces the soil plough horizon disturbance, reduce the change volume of plant growth topsoil structure, avoid soil plough horizon to change influence plant growth.
In order to realize above purpose, the technical scheme that the present invention adopted is: a kind of separated method for root that is used for rhizosphere effect between the intercropping and interplanting system kind of original position research land for growing field crops, and its step is following:
1) adopts digging tool; Broadcast preceding or before a crop emerges the back other plants crop and broadcast in two crops; Between two crops; Vertically excavate wide 5cm wide hole groove apart from half place along it apart from the one of which crop row, the hole groove forms for deep-cut 10cm soil layer to set depth at every turn, and the every layer of soil that digs out is deposited in the both sides of hole groove respectively;
2) in the hole groove that digs, place, make at a distance from the root timber material and be close to a sidewall of cheating groove at a distance from the root timber material;
Every layer of soil backfill of 3) step 1) being dug out according to the level of former soil layer, every backfill one deck with the soil of backfill shakeout, compacting.
The tangible intercropping system of a rhizosphere effect of sowing said intercropping and interplanting.
Said is plastic foil or nylon wire at a distance from the root timber material.
Said digging tool comprises spade and shovel head, and a shovel front end is 5cm wide " C " shape structure, and the rear end is fixedly connected with said spade or one is connected.
The present invention adopts digging tool to excavate out the wide hole groove of 5cm, reduces hole well width 35-45cm, has reduced the soil amount of digging out and the change volume of topsoil structure; After having avoided the soil layer backfill, be prone to when irrigation or rainfall sink, crop is prone to fall; Influence plant growth, and cheat when groove excavates and adopt 10cm successively to excavate, guarantee original topsoil structure as far as possible; Can more directly, more accurately study in the intercropping and interplanting system a rhizosphere effect of sowing, avoid in the root process influence to result of study.The width of cheating groove in addition can carry out before two crops are broadcast much smaller than two crop spacings, also can a crop emerge the back other carry out before planting crop and broadcasting, workable.The soil that digs out in addition is less, and labour intensity is little.
