Problems solved by technology

Because it is difficult to effectively control the cutting density with this seedling raising method, it is impossible to accurately estimate the number of cuttings, and there are disadvantages such as inconvenient transplanting, which brings many adverse effects on production operations.
For example, it is difficult for operators to carry out cuttings according to a certain row spacing in the actual operation process. On the one hand, this will lead to uneven cutting density, and differences in rooting speed and quantity. At the same time, it is not conducive to accurate calculation of the number of cuttings. seedling phenomenon

Embodiment 1 to 3 and comparative example 1 to 3

[0061] After mixing the perlite and northeast peat evenly according to the ratio shown in Table 1 below, put it into a 128-hole standard plastic tray (540mm×280mm×40mm), and use the listed river sand as a control; Put it down 10cm from the ground and repeat twice to make the substrate contact closely. Place the seedling tray with the substrate on the seedling rack. Each embodiment is prepared to plant 20 plug chrysanthemum seedlings.

[0062] Preparation before cutting

[0063] The day before the preparation of cutting chrysanthemum seedlings, water the hole tray thoroughly to make the substrate fully moist. Cuttings of spikes

[0064] The chrysanthemum (" Shenma " kind) seedling that arranges into length and has two expanded leaves of 5 cm is inserted in the hole plate, one plant in each hole, and the depth is 1.5 cm in the insertion matrix (the matrix volume of each hole is 27 cubic centimeters) ), water thoroughly so that the plants are in close contact with the substra...

Embodiment 4 to 6 and comparative example 4 to 5

[0076] Carry out chrysanthemum seedling cultivation and index determination in a manner similar to that of Example 3, except that the cutting depths shown in Table 2 below are used. The measuring method of root number is as above; And lodging rate is the percentage of the total seedling number of lodging seedling number in all 20 plug trays of each embodiment accounted for 20 plug trays. The results are shown in Table 2 below.

[0077] Table 2 Effects of different cutting depths on rooting and lodging of chrysanthemum seedlings

[0078]

[0079] From the results in Table 2, it can be seen that the number of roots will be affected if the cutting depth is too deep or too shallow, and if the cutting depth is too shallow, the lodging rate will increase significantly.

Embodiment 7 to 9 and comparative example 6 to 7

[0081] Cultivation of chrysanthemum seedlings was carried out in a manner similar to that of Example 3, except that chlorothalonil was used at the concentration shown in Table 3 below. Count the number of diseased seedlings before transplanting, and then divide by the total number of seedlings to calculate the incidence rate.

[0082] Table 3 Effects of different chlorothalonil concentrations on rooting of chrysanthemum seedlings

[0083]

[0084] It can be seen from the results in Table 3 that if the dilution factor is greater than 1000 times, for example reaching 1100 times, the incidence rate will increase significantly.

Abstract

The invention relates to a chrysanthemum plug seedling medium, which comprises perlite and turf with the volume ratio being 2:3 to 3:1. The invention also relates to a method for chrysanthemum plug seedling by employing the medium. With the adoption of the medium or the method the survival rate of chrysanthemum seedling can be improved, the cross infection of diseases and insect pests can be reduced, and the cost of the chrysanthemum seedling is obviously lowered.

Description

technical field [0001] The invention relates to a horticultural cultivation substrate and a method for raising seedlings, in particular to a substrate for growing flower plug seedlings and a method for using the substrate to raise flower plug seedlings. Background technique [0002] The scientific name of chrysanthemum is Dendranthema morifolium Tzvel, which belongs to the perennial root herbaceous plant of Asteraceae Chrysanthemum, and is a traditional famous flower of my country. Chrysanthemum has been cultivated and selected for a long time from the original wild species, and has developed into one of the most abundant cultivated plants in the world. It occupies an important position in the world's flower industry and is one of the four major cut flowers. According to statistics, the total number of chrysanthemum varieties in the world is about 20,000 to 30,000, and China has more than 3,000, which belong to 22 types. Chrysanthemum has so many varieties and variant types...
