Embodiment 1
[0052] Example 1: Preferred abutment method
[0053] Large-grain coffee rootstock seedlings are placed in a pot before the cotyledons are flat, and the true leaves have not yet grown. The diameter of the pot is 16cm and the height of 20cm. The pot is divided into 2 parts of equal space with a straight clapboard over the center of the seedling pot, at the center of the pot. , plant 2 large-grain seedlings on both sides of the partition, and place 3 drippers respectively. The drippers are 2cm away from the center point of the seedling pot and are distributed in a 120-degree fan shape. The distance between the two adjacent drippers is equal, and the two sides of the fan shape The distance from the partition is 30 degrees ( figure 2 Left), cultivate for 5-6 months along the center of the seedling pot to the dripper line, all drippers are expanded by 2cm, and continue to cultivate for 5-6 months ( figure 2 right). Drop fertilizer once every 2 months, and drop 0.5L of 0.1% water...
Embodiment 2
[0056] Embodiment 2: The influence of drip irrigation and fertilization dripper position, fertilization amount, and fertilization frequency on the root configuration of large seed coffee rootstock seedlings and the state of root system after abutting
[0057] In the test of table 2, 1 large seed stock seedling is planted at the center of the seedling pot, and each treatment is co-cultivated for 10 months;
[0058] In the test of table 3, 2 large seed stock seedlings are planted on both sides of the center clapboard of the seedling pot;
[0059] Other specific test procedures and results are shown in Table 2 and Table 3.

Embodiment 3
[0069] Example 3: Effects of plant ash application time, application amount and application location on root rejuvenation of grain coffee in the field
[0070] The specific process and results are shown in Table 4 and Table 5;
[0071] Table 4 Root rejuvenation of grain coffee in the field with different experimental treatments (1st year)
[0072]
[0073] Table 5. Root rejuvenation of grain coffee in the field with different experimental treatments (the 3rd year)
[0074]
[0075] Improving the root growth status of medium-grain coffee in continuous cropping obstacle gardens is the basic guarantee for improving the survival rate of ligation. By comparing the dry matter mass and root activity of plant roots under different plant ash application methods, it was found that under the same plant ash dosage, the application effect of semicircular furrows and longer square furrows was better. The plant ash was applied in a semi-circular ditch, and it was found that the annual ...
