THE IMPORTANCE OF CROTALARIA JUNCEA L.

In this article, the increase of salinity and salt residues as a result of a sharp decrease in water resources in the coastal areas and the role of the drought- and salt-resistant tropical plant Crotalaria (Crotalaria juncea L.) in reducing salt residues, as well as the effect of the use of stimulants on the level of salinity and the use of fertilizers as a solution to these problems, are described. When planting Crotalaria seeds, treating them with Geohumat stimulator, during the budding and flowering phases of the growing season, the dry residue in the 0-30 cm soil layer is -0.108, when fed with NPK - 20% liquid fertilizers at the rate of 1.5 kg per hectare; HCO3—0.006; SO3-2-0.005; Cl - 0.003; SO4-2 - 0.058; the sum of components - reduced to, the degree of salinity is from strong to moderate salinity and dry residue in the 30-50 cm layer is –0.050; HCO3 - 0.006; SO3-2 - 0.002; Cl - 0.005; SO4-2 - 0.038; the sum of components - decreased to 0.265%, and the salinity level changed from moderate to weak salinity.本文阐述了沿海地区水资源骤减引发的盐度升高与盐渍残留问题，以及耐旱耐盐热带植物猪屎豆（Crotalaria juncea L.）在缓解盐渍残留方面的作用，同时还介绍了施用刺激剂对盐度水平的影响，以及利用肥料作为上述问题解决方案的相关内容。在播种猪屎豆种子时用GeoHumat刺激剂处理种子，并在生育期的现蕾与开花阶段以每公顷1.5千克的用量施加20%浓度的氮磷钾（NPK）液态肥料，此时0-30cm土层的干盐残留量为-0.108，其中HCO3^-为0.006、SO3^2-为0.005、Cl^-为0.003、SO4^2-为0.058；各组分总含量降至，盐度等级由强盐化转为中度盐化；30-50cm土层的干盐残留量为-0.050，其中HCO3^-为0.006、SO3^2-为0.002、Cl^-为0.005、SO4^2-为0.038，各组分总含量降至0.265%，盐度等级由中度盐化转为弱盐化。
