When in use, the slow-release foliar fertilizer is prepared according to the weight ratio of 1: mixing with deionized water at a weight ratio of 500, and diluting.
1. The test varieties are as follows: bright red 168 tomato, test soil: 19.2mg/kg of available phosphorus and 182.0mg/kg of available potassium; 9.1 percent of organic matter, 0.60 percent of total nitrogen, 0.21 percent of total phosphorus and 1.05 percent of total potassium.
2. Test method
And (3) test treatment: the test field is divided into 30 portions, each portion is 16m2Wherein 30 parts are divided into 10 groups, each group comprises 3 parts, the double-row cultivation is carried out, the row spacing is 50cm, and the plant spacing is 50 cm.
3. The slow release fertilizer of the embodiment 1-10 is sprayed once to each group respectively at the seedling stage, before flowering and after flowering after transplanting, the spraying amount is 0.5kg each time, the conventional fertilization and farming level and the cultivation management level of each treatment are consistent, the average single fruit weight and the abnormal fruit rate are calculated, and the test results are shown in table 1.
TABLE 1
As can be seen from the table 1, the slow-release foliar fertilizer can obviously improve the fruit weight of crops and reduce the rate of abnormal fruits.
Compared with the examples 1 to 3, the slow-release foliar fertilizer prepared from different raw materials can affect the fruit weight and the rate of malformation of crops, wherein the example 1 is the optimal ratio.
Comparing example 1 with example 4, it can be seen that if potassium dihydrogen phosphite (potassium fertilizer) in the slow-release foliar fertilizer is replaced, the fruit weight and the rate of abnormal fruit are significantly affected.
Comparing example 1 with examples 5 and 6, it can be seen that the selection of different copper fertilizer, calcium fertilizer, zinc fertilizer, manganese fertilizer and potassium fertilizer can significantly affect the fruit weight and the rate of abnormal fruits, wherein example 1 is the selection of copper fertilizer, calcium fertilizer, zinc fertilizer, manganese fertilizer and potassium fertilizer, which can significantly increase the fruit weight and reduce the rate of abnormal fruits.
Comparing example 1 with examples 7 and 8, it can be seen that the addition of the modified attapulgite prepared by the present invention can significantly increase the fruit weight and reduce the rate of deformity, while the addition of unmodified attapulgite has little effect on the fruit weight and the rate of deformity.
As can be seen from comparison of example 1 with examples 8, 9 and 10, the modified attapulgite prepared in example 8 can significantly improve the fruit weight of crops and reduce the rate of malformation compared with the slow-release foliar fertilizer prepared from modified attapulgite prepared by other methods.
