The experiment was set up in the 6th group of Luji Village, Daxing Town, Suyu County. The soil for the test was fluvo-aquic soil developed from yellow-flush alluvial deposits. The tree age was 3 years and the growth was balanced. When the experimental plot was applied in mid-February for 18,000k years of organic manure, the N, P, and K contents of the tested fertilizers and various trace elements (including N16, pZo, 6 and K Knives 8) were 30%, and the mulberry special fertilizer was used in spring. On the 26th of the month and the summer on June 6th, it was turned into the mulberry field. Through the analysis of soil testing and formula application, only cK (urea, calcium superphosphate) and mulberry special fertilizer were used in this experiment. cK: Apply urea slokg+ phosphorous monophosphate 375kg per lhmZ; A: Apply fertilizer 750kg per lhmZ (same amount of spring and summer fertilization, 50% each). When each plot is 40, randomly arrange and repeat 3 times. In each plot of the experiment, 5 representative strains were continuously selected for spot inspection to examine the mulberry leaf yield, quality, the appearance of mulberry trees, yellow fallen leaves in autumn, and changes in soil nutrients.
41.3 effective shoots were applied for special fertilizer, while there were only 363 CKs and a net increase of 4.6 roots. At the same time, it can be seen from the mulberry branches that the diameters of the five plants before the experiment are basically the same, but after the autumn test, the specific fertilizer is increased by 105.gmm compared to the cK, but the CK is more effective than the spring after autumn. However, the diameter of the five plants was reduced by 1.gmm. From the above two comparisons, the application of special fertilizer than CK, regardless of the number and thickness of branches increased than before fertilization, indicating that special fertilizer nutritional balance, the effect is significant. At the same time, the number of yellow leaves was investigated to explain the plentiful and balanced nutrition of the mulberry soil. From Table 4, it can be seen that the use of special fertilizers due to rich nutrition, balance, fertilizer utilization, so the application of special fertilizer yellow leaves less than 6.4% cK.
The soil nutrient in the mulberry field was analyzed using the soil testing and formula fertilization meter, and reasonable fertilizer measures were adopted to analyze the yield and quality of mulberry leaves. According to the calculation, the total annual cost of using mulberry special fertilizer is 740 yuan per zhn, and the CK cost is 602.6 yuan per lhoZ. Special fertilizer can be used to increase the yield of mulberry leaves by 59 lokg per year for IhmZ, 7 sheets for sericulture, and 312 kg for harvesting. The price of 3744 yuan per Ihm is 3606.6 yuan, and the economic benefit is extremely significant. Because fertilization by soil testing and formula fertilization meter ensures soil nutrient balance, formula is reasonable, fertilizer utilization rate is high, mulberry growth is good, yield is high, quality is good, and economic benefit is significant. It is an effective increase in production efficiency. Measures.
