The length multiplied by the width is 10 meters multiplied by 2 meters, and the furrows are isolated among cells.
Treatment (1): and (5) applying 2500 kg of mature rotten chicken manure and 50 kg of nitrogen-phosphorus-potassium (20-10-15) ternary compound fertilizer per mu of conventional fertilizer and applying 30 kg of urea.
Treatment (2): conventional fertilizer + clear water Control (CK). Respectively, the first cluster walnut and the test are performed at the same period.
Treatment (3): the conventional fertilizer and the flower-promoting and fruit-promoting type microelement liquid fertilizer provided by the invention are sprayed on leaf surfaces, the dilution concentration is 600 times, the fertilizer is sprayed on the first cluster of walnut trees at a large start, the spraying is carried out for three times, each time is separated by 15 days, and the using amount is carried out according to the product specification.
Results and analysis
Influence on tomato production factors
According to the investigation of each test cell in different growth periods of the tomatoes, the plant height, the number of fruits per plant and the average weight of the fruits are obviously different among 3 treatments, and the fruits are uniform and bright in color in the treatment (3) compared with the fruits in the treatment (1) and the treatment (2) in the appearance of the fruits.
Effect on tomato yield
The test results show that the treatment (3) is carried out every 667m2The tomato yield is 6453.2kg, and the net yield is increased by 10.6 percent compared with the yield increased by 620.3kg in the treatment (1); compared with the treatment (2), the yield of the product is increased by 550.2kg, and the yield is increased by 9.3%.
On the basis of conventional fertilization, 50ml of fertilizer to be tested is added with 30 kg of water, the fertilizer is sprayed once every 15 days from the fruiting period of the tomatoes and is sprayed for 3 times totally, compared with the conventional fertilization in the same period, the number of fruits per plant and the weight of each fruit are increased, the yield is improved, and the average yield is increased every 667m2The yield is increased by 620.3kg, the yield is increased by 10.6 percent, and the yield difference reaches an extremely obvious level.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiments shown in the examples are only one of the embodiments of the present invention, and the actual content is not limited thereto. In summary, those skilled in the art should appreciate that embodiments and examples similar to those of the present invention can be devised without departing from the spirit and scope of the invention.
