Layering propagation method for tomatoes

Abstract

The invention relates to a layering propagation method for tomatoes. The layering propagation method for tomatoes comprises the following steps: selecting healthy mother branches close to the ground, maintaining 20 centimeters of flower heads on the branches in heights, completely pressing stems with knobs in soil, pressing nutrient oil blocks above the pressed stems so that new roots are grown out on the stems pressed in the soil 5-7 days later, performing once purging transplanting in 7-10 days before planting so that the roots are disconnected with the parts connected with the mother branches, and combining hardening of seedlings so that wounds are healed; selecting a piece of paddy field, performing deep ploughing in the depth of 25-30 cm so as to facilitate soil aging, wherein base fertilizers needs to be applied additionally during deep ploughing, 500-1000 kg of decomposed manure or 20-25 kg of ammonium sulfate, 10-12.5 kg of urea and 20-25 kg of calcium superphosphate are applied in every mu of paddy field, and the paddy field is leveled; transplanting to the leveled paddy field in a horizontal cultivation manner as much as possible, and enabling the roots to be cultivated shallowly but not deeply, so that seedlings are fallen in the soil only; enabling heads of growing points to face the north so that the heads are automatically raised after cultivation; repeating the operation, and enabling the seedlings to be in a good order, so that fruits are above 20 centimeters in heights and are easy to manage, the yield is high, trees are not too high, and a good foundation is provided for high yield.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for tomato propagation by pressing branches. Background technique [0002] Tomato press branch propagation is mainly used for the cultivation of autumn stubble tomatoes. Its main advantages are: first, it can directly grow seedlings in the tomato production moisture, effectively solving the problem of the shortage of heavy cropping tomato seedlings; , do not need to consider looking for other plots; the third is that the seedling breeding period is shortened by nearly 20 days, which effectively increases the tomato fruiting period and increases tomato production by nearly 3 layers. [0003] The usual method for raising seedlings by pressing branches is mainly to select healthy fork branches, press the fork branches on the ground at the position of 2-3 nodes later, and then dig 1-2 inch small ditches along the direction of the branches, fertilize and apply pesticides. 1...

But the disadvantage is that it is time-consuming, sometimes it is difficult to control the amount of fertilization and pesticide application, which can easily lead to uneven emergence and large quality gaps, etc.
