Vegetable pea cultivation techniques
Second, the choice of soil selection of loose soil, rich in organic matter, good drainage and irrigation of sandy loam, the most appropriate PH value between 6.0 ~ 7.2, avoid continuous cropping.
Third, the appropriate time sowing, reasonable close planting time for the general sonar period from late September to early October. Single-row double row planting. Generally, it is 80 centimeters wide, 30 centimeters wide and 40 to 45 inches apart. Each pond sows 2 to 3 seeds. The pond distance is 15-20.
4. Fertilizer and Water Management The peas in chyme generally do not need to be irrigated within one month after sowing (ie, early flowering period) to reduce root rot. Fertilization is usually carried out at the time of the first irrigation, and 50 mu of Mushi calcium and 10 parts of potassium sulfate are sprayed. During the picking period, fertilizer is applied every 7 to 10 days. Each time, the compound fertilizer is used for watering, or urea is combined with 5 to 10 and ammonium bicarbonate. Flowering can spray 5 ~ 25 mg / l of a-naphthylacetate can increase the fruit set rate, the period of mussels with potassium dihydrogen phosphate 100g plus borax 50 g water 50? spray 2 ~ 3 times.
Fifth, cultivating and weeding, cutting and cultivating vines, cutting front view weeds, combined with small earth. Weeding and weeding 1 or 2 times, we can also use Weibu 1000 times liquid spray weeding 1 times. If weeds are enclosed and lined with weeds, we can use herbicides such as glyphosate to eliminate weeds. Extend vines should promptly introduce vines. During the seedling stage, the water should be stagnated. When the drought occurs, the horse water will be timely fed to meet the drought, and in case of heavy rain, the gutter will be drained in time.
Sixth, timely picking flower Xie 5 to 7 days after picking, grasping the seeds began to form, light see grain traces, pods turn dark color wide straight picking is appropriate. Should be light to prevent pulling stems, generally 3 to 5 days once.
VII. Pest Control
1. Root rot: Rotation and timely irrigation and drainage are used, and soil can be disinfected with Dixon.
2. In the middle and late period, it is mainly powdery mildew, treated with 20% triadimefon or 20% thiophanate-methyl. 3. Insect pests: mainly L. sativae and L. chinensis, supplemented by aphids. The former is controlled by alternating use of efford or avermectin, and the latter is better controlled by imidacloprid or big pirenone.
