Lentils, also known as eyebrow beans, cut beans, legume perennial or annual twining vine plants, to the young pods or mature beans for food, nutritious, with the spleen and dampness and other medicinal effects. Purple lentil belongs to a common variety of lentils, divided into purple side of white lentils and purple lentils, the appearance of purple, pod quality and white lentils similar to the pod meat is thick, soft taste after cooking, popular with the majority of consumers, the market demand is large, now its high-yield cultivation techniques are introduced as follows.

Lentils are generally cultivated in the open ground in the summer, generally in mid-January can be guaranteed to be continuous, but the climate of different regions is not the same, so it is not the same sowing time, such as the Yangtze River Basin lentil planting time in May to July, while the planting time in northern China is more in June. Lentils can be divided into white lentils, green lentils and purple lentils according to the color of their pods, of which the green lentils are thin and crisp; purple lentils are similar to white lentils, with thick pods and fluffy after cooking. Sowing combined with tilling per mu into the mature farmyard manure 3000 kg and the appropriate amount of fertilizer as a base fertilizer, fertilizer and soil mix, in raking the ground. Lentils are usually sown by direct seeding, furrowing or hole sowing methods, controlling the plant spacing at 35-50 centimeters, row spacing at 100-130 centimeters. Generally sowing 3-4 seeds per hole, and leaving 2 seedlings per hole after emergence.

Lentils have a strong drought resistance, watering in the seedling period, watering in the elongation period and podding period, generally in the elongation period need to be watered 1-2 times, watering every 10 days during the podding period. After watering should be timely plowing and weeding, at the same time combined with the top, in order to prevent the fall of flowers and pods or futile growth, pre-flowering fertilizer should be less thin fertilizer, post-flowering pods fertilizer should be repeated. Plowing should be shallow, one year a root injury, fertilization should pay attention to the reasonable combination of nitrogen, phosphorus, potassium, nitrogen fertilizer application. Before pulling the vine can be set up, or pulling the vine in time after the rope will lead the vine on the shelf, leading the vine to make the stems and vines evenly distributed in the fence frame, when the main vine grows to 1.5 meters can be pruned and centrifuged to promote multi-branched and multi-forked vines, the early flowering of the pods.

Lentil diseases are mainly watering, insect pests are mainly aphids and pod borers, aphids can be controlled with imidacloprid and amidacloprid, the use of concentration should be noted. The pod borer to larvae moth beans, serious when the whole pod to eat empty, can be taken to foliar spray 20% cyhalothrin 2500 times liquid or 50% fenpropathrin 1000 times liquid control, weekly replacement, so as not to produce resistance.
