First, pay attention to nurturing seedlings and strong seedlings is the prerequisite for the spring of Ziyun Ying. In winter, Ziyunying has strong vitality and many root systems. Although the growth rate of stems and leaves is slow, the stem base has begun to branch and differentiate, and it is the time for the foundation of spring hair. Therefore, strong seedlings must be cultivated. The criteria for strong seedlings are: seedling height 8 cm to 10 cm, two or three branches, total number of seedlings per 667 square meters of field spring (including branching) 800,000 seedlings. The specific measures are:
1. Open up new ditch, resist drought, prevent stains, and Ziyunying are both afraid of stains and afraid of drought. Therefore, after the late rice is harvested, it is necessary to open new ditch in time to deepen the old ditch, so that "three ditch" (main ditch, Weigou, Xianggou) supporting. Generally every 2 meters or so - open the car ditch, groove width 20 cm, ditch depth 30 cm. The bottom of the main sulcus and the ditch must be broken by the plow, so that the ditch can communicate with each other and can be filled with energy. For the grazing paddy fields with high groundwater level, a new type of permanent narrow-deep type drainage sluice should be constructed. Generally, the row leaching ditch is about 1 meter below the field surface.
2. Pu Shi wax fertilizer, warm winter freeze temperature, the lack of available phosphorus in soil, phosphate fertilizer should be increased, all over the experiment shows that the phosphorus fertilizer in the late rice in the second cultivator for rewatering fertilizer application of the best yield. If not applied, pre-winter application of superphosphate 20 kg to 25 kg per 667 m2 should be sufficient to increase the effect of nitrogen addition by phosphorus. After winter, heat preservation fertilizer should be applied depending on the seedlings. Generally, about 667 square meters of soil miscellaneous fertilizer or garbage fertilizer should be used to protect the seedlings. About 667 square meters of field can be applied to pigs, 300 kg of cow dung and 500 kg of vegetation ash.
Second, pay attention to promoting spring hair is the key to seize the high yield of milk vetch. Ziyun Ying high-yield indicators: plant height above 1 meter, stem diameter 0.3 cm -0.4 cm, fresh weight of each plant 8 grams -10 grams. The specific measures are:
1. Early Qing Dynasty “Sangou†In order to create a good dry and wet soil condition for Ziyun Ying’s spring, it is necessary to drain the drain in time in early spring so as to stop the rain.
2. After the application of the seedlings, the growth of the main stem and branches of Ziyunying was accelerated and the demand for nutrients increased. The low temperature in early spring and the slow release of soil nutrients do not meet the longevity of the milk vetch. Therefore, we must look at the fields and see how the seedlings can effectively raise the seedlings. Generally urea 2 kg -3 kg per 667 square meters, potassium chloride 3 kg -5 kg, can achieve "small fertilizer for large fertilizers, inorganic fertilizers for organic fertilizer" purposes.
In addition, we should pay attention to pest control. Diseases of Ziyunying mainly include sclerotinia and powdery mildew. Pests mainly include thrips, aphids, and leaf miners, so pest and disease prediction should be done in time, and comprehensive prevention and control should be done seriously. For sclerotinia, powdery mildew, Bordeaux mixture can be used to kill and spray 1000 times for spray control, but also for every 667 square meters of Milky Way field lime 50 kg -100 kg. For the thrips, aphids, and leaf miners can be used to control the net, Biting and other agents.
