甜菜是喜中性或微硷性土壤的作物。在低湿易涝且偏酸的白浆土上增施石灰，以冲和土壤酸度，改善土壤理化性状，促进有益微生物的活劝，从而可获得较好的产质量。 1987年于黑龙江八五○农场25分队进行了石灰改良白浆土种甜菜试验(熟石灰由卫星糖厂提供)。设4个处理:①石灰50公斤/亩耙入;②50公斤/苗条施;③100公斤/亩耙入;④100公斤/亩条施;无石灰区为对照。对比法排列,3次重复,4行区,行长5米,行距60厘米,小区面积12米~2。试验地前茬小麦,5月1日取样测定基础肥力为:有机质含量4.88％,全氮0.267％,全磷0.1316％,水解氮11.26毫克/100克土,有效磷5.93毫克/100克土,有效钾19.57毫克/100克土,pH值6.17。5月1日播种,播前
Beets are crops that love neutral or slightly alkaline soil. Lime is added to white muddy soil with low moisture and waterlogging and slightly acid so as to wash red soil and acidity, improve the physical and chemical properties of soil and promote the active persuasion of beneficial microorganisms so as to obtain better production quality. In 1987, a team of 25 members of the 2550 farm in Heilongjiang carried out a lime-improved white soil beet trial (hydrated lime supplied by satellite sugar factory). Set 4 treatment: ① lime 50 kg / mu rake into; ② 50 kg / slender facilities; ③ 100 kg / mu rake into; ④ 100 kg / acre facilities; no lime as a control. Contrast arrangement, 3 times repeated, 4-line area, governor 5 meters, line spacing 60 cm, the plot area of 12 m ~ 2. The pre-cropping wheat on May 1 was sampled on May 1, and the basic fertility was determined as follows: organic matter content 4.88%, total nitrogen 0.267%, total phosphorus 0.1316%, hydrolyzed nitrogen 11.26 mg / 100 g soil, available phosphorus 5.93 mg / 100 g soil, effective Potassium 19.57 mg / 100 g soil, pH value 6.17 May 1 Sowing, sowing
