The flowers bloom in autumn and winter. Racemes axillary, 15-25 cm long, erect and stout, often 2 to many flowers growing on nodes of inflorescence axis; calyx broadly campanulate, 5-toothed, upper 2-lobed; Corolla white or purplish red, 15-18 mm long, with 2 auriculate appendages on both sides of the base of the flag. Pods oblong, flattened, slightly curved, 5-7 cm long and 1.4-1.8 mm wide; seeds oblong, white or purplish black.

Riverside roadside, field edge land, before and after the house can be cultivated, low-lying land, saline-alkali land is not suitable for cultivation.

Second, select fields with high terrain and good drainage for soil preparation and fertilization, and cultivate them carefully. Combined with soil preparation, apply sufficient base fertilizer: 3000 kg of soil miscellaneous fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. And made a high bed 1.3 meters wide waiting to be sown.

Third, sow white lentils and propagate with seeds. The sowing time is spring sowing. Direct seeding is often used, and seedlings can also be raised and transplanted. In the direct seeding, the seeds of white lentils were sown on the whole border surface according to the row spacing of 60 x 50 cm, and watered to preserve soil moisture to facilitate seedling emergence. Put 3-5 seeds in each hole. Seedlings will be evenly sowed on the whole border, watered to preserve moisture, and covered with a layer of plastic film, strengthen the management of the seedling bed, the seedling height of about 10 cm can be transplanted. Transplant the white lentil seedlings according to the row spacing of 60 x 50 cm and plant on the whole border surface, watering to preserve soil moisture in order to survive.

Fourth, field management white lentil seedlings or after transplanting survived, attention should be paid to ploughing and weeding. Pay attention to watering in dry weather and timely drainage in cloudy and rainy weather. Seedling height of 30 cm should be set up, or intercropping some jade or sorghum and other tall crops for its vines to climb, in order to facilitate ventilation and light. Topdressing should be applied once during the flower bud: 5 kg of urea and 5 kg of potassium diphosphate per mu.

5. Control of diseases and insect pests the main disease of white lentil is rust, which can be controlled with sodium rust or strychnine at the initial stage of the disease.
