In order to grope for the effect of the increase in yield of Wei Luxin 99 plant fertilizer produced by Hengyang Chunjiang Biological Co., Ltd. on the bitter night leaf, we were commissioned by Mr. Cheng Gang to perform bitter nights from March 2004 to May 2004. Field trials of vegetables are summarized below:
1, test materials and methods
1.1 Test site: Zhouzi Village, Zhoubei Village, Chengbei Town, Yuzhou District, Yulin City, an area of ​​667m2.
1.2 Test soil: This experiment is a mountain-fed tide soil with medium soil fertility. Before it was used as rice, organic matter in soil was 1.42%, total nitrogen was 0.058%, hydrolyzable nitrogen was 50ppm, available phosphorus was 6ppm, available potassium was 30ppm, and PII was 6.8.
1.3 Fertilizers for testing: Weilvxin Brand 99 plant fertilizer (water agent), urea (containing N46%), compound fertilizer (containing N15%, P2O15%, K2O15%).
1.4 Test varieties: bittersweet
1.5 Test methods
1.5.1 Test design: (1) 15 days after transplantation with 99 plant fertilizers 500L/667m2 watered 90 kg, sprayed on ten surfaces; (2) with 99 plant fertilizers 500mL/667m2 watered for 30 days after transplantation 0 kg Foliar spraying; (3) 50 days after transplantation with 99 plant fertilizers 500mL/667m2 watered 80 kg foliar spray; (4) 15 days after transplantation + 35 days after transplantation each with 99 plant fertilizer 500mL/667m2 watered 90 kg of foliar spray; (5) Control (do not spray 99 phytofertilizers) in total of 5 treatments, three replicates, arranged in sequence, plot area of ​​13.4 m2 (length 11.16 m, width 1.2 m, excluding interregional gaps).
1.5.2 Test operation: 667m2 of the test field is uniformly applied with 8kg of urea for the seedling stage. During the growth period, 70kg of compound fertilizer is used per 667m2, which is called the second topdressing. The first time after spraying lOkg for 5 days after transplantation, each interval 15 big time, 20kg per time. Bittersweet sowed on February 15th, transplanted on March 7, leaf age 5-6 leaf age, planting specifications for 30cm30cm, uniform planting 180 per plot,
1.5.3 Test implementation: The experimental bitter and late food was transplanted on March 7th, on March 22th, and on the 4th with foliar spraying of 99 plant fertilizers; on April 11th, treatments 2 and 4 were carried out with foliar spraying of 99 plant fertilizers; On April 26th, Treatment 3 carried out the foliar application of 99 plant fertilizers; on May 9, the unified subarea was harvested for production.
1.5.4 Test observation records: After the test was transplanted, the growth dynamics of the late-vegetables were recorded at fixed-point observations, and the plant height and leafing speed were recorded respectively. The yield was calculated and harvested in each area during the harvest period, and 10 samples were taken to examine economic traits. After the end of the trial, the data was collated and a summary report was written.
2, test results and analysis
2.1 Effect on growth and development The yield of bitter tuberose leafy vegetable crops is mainly composed of the growth and development of leaves during vegetative growth. From the perspective of the growth dynamics of bitter nightweed (see Table 1), the growth of all treatments was steadily increased compared to the control, and the treatments of 99 plant fertilizers were applied 15 days after planting and 15 days after planting and 35 days after planting. The bitter nightgrass grows more obviously. After spraying on March 22, the number of plant leaves was 9.8 and 8.8 leaves. Plant height was 22.8cm and 23.3cm, which was 1.8 leaves and 0.8 leaves compared to the control 8.0 leaf. Other treatments increased by 0.6-1.6 leaves, plant height increased by 1.5cm and 2.Ocm from the control 21.3cm, an increase over other treatments
0.7-1.2cm. In the middle and late period, the growth was most prominent at 35 days after planting and 15 days after planting and 35 days after planting. Spraying was conducted on April 11 and on the 8th day before harvest, the number of plant leaves was 32.3 leaves and 31.9 leaves. Plant height 63.7cm and 64.3cm, leaves increased 2.6 leaves and 2.2 leaves compared to the control 29.7 leaves, an increase of 0.3-0.7 leaves compared to other treatments, plant height than the control 60.9cm, an increase of 2.8cm and 3.4cm, an increase of 1.5-2.1 than other treatments Cm. The performance of spray treatment 50 days after planting was slower than other treatments, but it was also more pronounced than the control.

The yield of fresh vegetables in the test area was reduced to yield, and the area containing the ditch was included.
2.2 Effects on economic traits Fresh crops were examined for economic traits at various harvesting dates (see Table 2). The results showed that the best performance was achieved with the application of 99 phytofertilizers 35 days after planting and 15 days after planting and 35 days after planting. The fresh weight of the plants was 0.59 kg and 0.57 kg, which was 0.48 g more than the control and the weight gain was 0.11 kg and 0.09 kg. The total number of leaves of the plants increased by 2.7 and 2.3 leaves, respectively. The petiole thickness was 0.12 and 0.1 cm thicker than the control. . Followed by spraying 15 days after planting and spraying 50 days after planting. The traits were between 35 days after planting and 15 days after planting + 35 plants after spraying and control. Average fresh weight per plant. The weight gain was 0.06 kg and 0.05 kg compared to the control.

2.3 Effects on Yield The production of Wei Luxin 99 plants with bitter and evening foliar spray has obvious effect on yield increase. After the test was conducted on May 9th, the results were measured (see Table 3). The average output of 667 m2 was the highest after planting35 Sprayed and sprayed 15 days after planting and 15 days after planting, the plant was sprayed for 35 days for 15 days. The yield of fresh vegetables was 5199.0 kg and 5031.0 kg, which was 17.0% higher and 13.9% higher than the control, followed by 15 days after planting. Spraying and spraying 50 days after planting and spraying, the yield of fresh vegetables was 4851.0kg and 4794.0kg, which increased 90.8% and 8.6% over the control.
