Example 5
And (3) treatment: in the main peach producing area Shuangping county, 9 peach gardens with similar soil conditions and the same peach varieties and tree ages are selected, wherein 1 peach garden adopts conventional fertilization as a reference 1, 1 peach garden adopts 70% of the conventional fertilization as a reference 2, and the rest 7 peach gardens adopt 15 kg/mu of soil conditioner in examples 1-3 and comparative examples 1-4 after peach trees are picked respectively on the basis that the total weight of the reference fertilization is reduced by 30%, and the peach gardens and the soil conditioners and base fertilizers are raked into surface soil of 40cm at the same time.
The conventional fertilizing amount comprises a base fertilizer and an additional fertilizer, wherein the base fertilizer comprises 1 ton of organic fertilizer and a compound fertilizer (N: P)2O5:K2O15: 15:15)40 kg/mu; additional fertilizer, compound fertilizer (N: P)2O5:K2O18: 12:18)60-80 kg/mu.
Picking the peaches in the mature period of the peaches, repeating the treatment for 3 times, selecting 5 peaches for each repetition, totally 15 peaches, measuring nitrate, soluble solid, titratable acid and vitamin C, and taking an average value, wherein the nitrate is measured by NY/T1279-. Sugar acid ratio ═ soluble solids/titratable acid. Specific results are shown in table 1.
TABLE 1 Effect of different treatments on peach nitrate, soluble solids, titratable acids, vitamin C content
As can be seen from Table 1, in the examples 1 to 3 of the present invention, compared to the control 1, the content of nitrate in the peaches is reduced by 44.3 to 46.4%, the content of soluble solids is increased by 13.2 to 15.1%, the content of titratable acid is reduced by 20.7 to 21.1%, the sugar-acid ratio is increased by 42.2 to 45.8%, and the content of VC is increased by 14.9 to 16%. Therefore, the soil conditioner provided by the invention can obviously reduce the content of nitrate and titratable acid in the peaches, improve the content of soluble total sugar and vitamin C, and improve the quality and taste of the peaches while reducing the application amount of the fertilizer by 30%.
Compared with the control 2, the content of nitrate in the peaches is reduced by 40.7-42.9%, the content of soluble solids is improved by 16.5-18.5%, titratable acid is reduced by 15.9-16.9%, the sugar-acid ratio is improved by 39.1-42.6%, and the VC content is improved by 17.5-18.6% in the embodiments 1-3. Therefore, the soil conditioner special for peach trees can obviously reduce the content of nitrate and titratable acid in peaches, improve the content of soluble solid and vitamin C and improve the mouthfeel of peaches.
In addition, in the case of the embodiment 1 of the present invention, when any one of the complex microbial inoculant, the wood vinegar, the biochar, and the humic acid is absent, the content reduction degree of the nitrate and the titratable acid is low, and the content improvement degree of the soluble solid and the vitamin C is small. Therefore, the soil conditioner special for peach trees has a synergistic effect among the components, can obviously reduce the content of nitrate and titratable acid in peaches, improves the content of soluble total sugar and vitamin C, and improves the quality and the taste of peaches.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
