During the summer months, greenhouse tomato production is challenged by the heat, causing yield reduction; therefore, we conducted a study to test the effectiveness of different foliar spray compositions for the improvement of Lycopersicon esculentum var. cerasiforme ‘Qianxi’ nutrition uptake and fruit yield. Two forms of silicon, two kinds of organic nitrogenous compounds and water as the control factor were two-two paired to become nine different recipes, which were as follows: CK (H2O), ISi (K2SiO3), organic silicon (OSi), potassium fulvate (BSFA), BSFA + ISi, BSFA + OSi, betaine (GB), GB + ISi and GB + OSi. The plants were sprayed three times during the period of the first, second and third truss fruit expansions with a 2-week interval. As a result, BSFA or K2SiO3 generated higher yield in plants compared with the other compositions. Also, K2SiO3 significantly enhanced the total nitrogen, phosphorus and potassium accumulation in fruit and the whole plant. Comparing across the nine recipes, BSFA + ISi, ISi and GB had improved the fruit yield by 17%, 12.7% and 9.5%, performing the best. BSFA + ISi, ISi and GB also improved the plant nitrogen uptake by 8.2%, 18.8% and 9.8%, as well as the potassium uptake by 16.2%, 12.3% and 15.2%, compared with CK, respectively. Thus, K2SiO3, BSFA and GB stimulated the plant nitrogen and potassium uptake, which improved the marketable yield.

叶面喷施硅酸钾、黄腐酸钾和甜菜碱通过促进植物对氮和钾的吸收提高夏季番茄产量

在夏季，温室番茄生产受到高温的挑战，导致减产；因此，我们进行了一项研究，以测试不同叶面喷雾组合物在改善番茄变种。樱桃形'千喜'营养吸收和果实产量。两种形式的硅、两种有机含氮化合物和水作为控制因子二二配对，形成九种不同的配方，分别为：CK（H2个O), ISi (K2个二氧化硅3个)、有机硅 (OSi)、黄腐酸钾 (BSFA)、BSFA + ISi、BSFA + OSi、甜菜碱 (GB)、GB + ISi 和 GB + OSi。在第1、2、3次桁架果实膨大期间喷3次，间隔2周。因此，BSFA 或 K2个二氧化硅3个与其他组合物相比，在植物中产生更高的产量。还有，克2个二氧化硅3个显着提高果实及全株总氮、磷、钾的积累。9种配方比较，BSFA+ISi、ISi和GB分别提高了17%、12.7%和9.5%的果实产量，表现最好。与 CK 相比，BSFA + ISi、ISi 和 GB 还分别提高了植物氮吸收量 8.2%、18.8% 和 9.8%，钾吸收量分别提高了 16.2%、12.3% 和 15.2%。因此，2个二氧化硅3个, BSFA 和 GB 刺激了植物对氮和钾的吸收，从而提高了商品产量。
