Comparative example 1
This comparative example is the same as example 1 except that it does not contain sludge/grapefruit peel activated carbon.
Comparative example 2
This comparative example was applied with only the same composted manure as in example 1.
Comparative example 3
This comparative example is the same as example 1 except that it does not contain waste lard.
Fruit setting rate: and randomly selecting 5 jujube trees as observation trees in each treatment, and randomly selecting 4 jujube hanging marks on each observation tree. Taking the jujubes as an example, the special fertilizer for the jujube trees and the fertilizer of the comparative example 1 are applied before the flowering phase respectively, and the flowering number of each jujube tree is counted after 1.5 months of application; fruit setting number: counting the fruit setting number on the selected jujube hangers during the flowering number measurement; fruit setting rate: the ratio of fruit set to flower set.
As can be seen from the graph 1, the fruit setting rate is effectively improved by applying the fertilizer, and the compound sludge/pomelo peel activated carbon prepared by sequentially impregnating iron and imidacloprid in the carrier with the sludge/pomelo peel activated carbon can improve the disease resistance of the jujube trees, effectively prevent insect damage to the jujube trees in the flowering phase, reduce fruit drop caused by insect damage and improve the fruit setting rate.
After the jujube is ripe, picking all fruits of the observation tree, counting the total number of the fruits and the number of cracked fruits of each tree, and calculating the fruit cracking rate, wherein the formula is as follows: the fruit cracking rate is equal to the fruit cracking quantity/the total fruit quantity multiplied by 100 percent
As shown in the figure 2, the fruit cracking rate is effectively reduced after the fertilizer is applied, because the composite sludge/pomelo peel active carbon in the fertilizer has a certain adsorption effect and a certain slow release effect, and the problem that the fruit is cracked due to the fact that the soil moisture is increased rapidly and the root system absorbs moisture rapidly because of the increase of rainfall is reduced. Secondly, the cracking point of the jujube cracked fruit is also a part for leading the epidermis to stop growing in advance due to the generation of plant diseases and insect pests, the EM bacteria can effectively prevent diseases and insect pests in the growth process of the jujube tree, the composite sludge/shaddock peel activated carbon can effectively prevent the plant diseases and insect pests, and the potassium humate can improve the resistance of the jujube, so that the fruit cracking rate is effectively reduced.
When the jujubes are ripe, the sweetness of the jujubes is evaluated. The test population is the general consumer population, the person who tastes normal and can make correct evaluation, and the person is 20 persons who are invited at random.
TABLE 1 sweetness evaluation
