豇豆种植步骤和时间：
1.长豇豆在春季种植，它的根系深，株型大，要选择土层深厚，弱酸性和肥沃的土壤来栽培，播种前先把土地进行深耕，施足底肥。长豇豆如果在早春种植,要在温室中先育苗，然后移栽和定植。当最低气温稳定在12℃以上时可以直接播种到泥土里，行距30-60厘米，株距30厘米左右，深度约5厘米。每一穴4粒种子，出苗后等长出真叶时要间苗，每穴留下2株健壮的苗。
2.长豇豆比较耐旱，在平日里要控制好浇水次数, 但是水分不足，又会抑制它的生长发育, 所以请结合本地的气候灵活掌握浇水次数。
3.当长豇豆开始长出藤蔓时, 要及时插架绑蔓，引导藤蔓缠绕上架往上长，长豇豆的藤蔓一般会长到两米以上,所以搭架的高度最好高于2.3米.
4.当长豇豆开出第一朵花后，就可以把第一花序以下,离地近的侧枝摘除，以保证主藤的强壮。再剪去一些老叶和病叶，使得植株底部的空气流畅。减少病虫害的发生 .
5.当长豇豆进入结荚高峰期时,最好再施一次追肥。
1. Long cowpea is planted in spring. Its root system is deep and the plant shape is large. It is necessary to choose a deep, weakly acidic and fertile soil for cultivation. Before sowing, the land should be deeply ploughed and enough base fertilizer should be applied. If long cowpeas are planted in early spring, they should be first raised in the greenhouse, and then transplanted and colonized. When the minimum temperature is stable above 12 ℃, it can be directly sown into the soil, the row spacing is 30-60 cm, the plant spacing is about 30 cm, and the depth is about 5 cm. There are 4 seeds in each hole. After emergence, the seedlings should be thinned when true leaves grow, leaving 2 robust seedlings in each hole.

2. Long cowpea is relatively drought tolerant, and the watering frequency should be controlled on weekdays, but insufficient water will inhibit its growth and development, so please flexibly control the watering frequency according to the local climate.

3. When the long cowpea begins to grow vines, it is necessary to insert the frame and tie the vines in time, and guide the vines to wrap around the frame and grow upward. The long cowpea vines generally grow to more than two meters, so the height of the frame is preferably higher than 2.3 meters.

4. When the long cowpea blooms the first flower, the side branches below the first inflorescence and near the ground can be removed to ensure the strength of the main vine. Trim off some old and diseased leaves to make the air flow at the bottom of the plant. Reduce the occurrence of pests and diseases.



5. When the long cowpeas enter the peak period of pod formation, it is best to apply top dressing again.
