Coix cultivation techniques

In the late autumn or early spring soil preparation 2 to plowing, tillage depth 25cm, in the application of organic fertilizer per hectare, while plowing 45000-7500okg, SSP 450-750kg. After the land is properly Gengpa every 2m or so to open a ditch, Goushen 20 ~ 30cm, as the drainage and irrigation channels. 2.3 Propagation Methods seed multiplication, both spring and summer sowing, Shuangliao to spring is appropriate. 2.3.1 The timing of planting in late April to early May sowing, the growth of long, high yield. Early planting, soil temperature is low, slow germination, seedling growth potential of the weak, vulnerable to smut; planting too late, short growth period, less tillering, low yield, and seed can not even mature. 2.3.2 Seed selection and treatment selection of seeds sown that year, avoid the use of aged seed. Election by sowing the wind, or water tablets election to election methods such as the white immature grain, not full of green grains and grain pest removal, selected tablets, full of seeds sown. In order to promote seed germination and the prevention of pests and diseases, seed treatment should be carried out before sowing. 5% available lime soaking 1 ~ 2d, and then rinse with water for later use. 2.3.3 sowing methods based on years of practical experience, should be used in Shuangliao drilling ridge, that ridge about 7em deep open ditch, the seeds were evenly spread trench, Futuhoudu about 3cm, after sowing must be suppressed. 2.4 2.4.1 Dingmiao field management about 6cm or so height grow 3-4 leaves, the room went close seedlings and weak seedling; grow 5 to 6 leaves, the spacing Dingmiao by about 10cm. Number of seedlings per hectare to retain 300,000 ~ 370,000, while on the Seedlings Deficiency Dingmiao for Planting monthly. 2.4.2 cultivation,[link widoczny dla zalogowanych], weed in thinning, weeding Dingmiao the same time, and the cultivators earth to prevent lodging. The growth and development carried out at least 3 times during the more than cultivators earth. 2.4.3 Water management in wet, dry, water, wet, dry and white management principles. Namely: wet seeding, dry jointing, booting water, enough water heading, moist filling, dry field harvest. Coix 2.4.4 pollination of flowering plants are dioecious different. The same first mature male inflorescence with female flowers are not synchronized,[link widoczny dla zalogowanych], often need different strains of pollination and fertilization. General can be pollinated by wind-pollinated, if the peak flowering plant with a rope vibration tools (morning l0: 0012:0 o time) to pollen flying, to improve the setting rate plays a significant role. 2.4.5 basic end of tillering fertilizer, topdressing of ammonium sulfate per hectare should be 150kg; booting topdressing of ammonium sulfate per hectare of 150kg, SSP 250kg; Coix basic pumping Qi Sui, after over 2% of available phosphate Spraying plants with half of the calcium solution. Pest and Disease Control 2.5.1 2.5 is Coix smut smut major diseases. Seedlings generally not easy to find, with the plant growth, the stems and leaves to form tumor-like body,[link widoczny dla zalogowanych], after the murder of ear swelling into a spherical or flat ball brown bag, inside is full of dark brown powder (the original pathogen basidiospores), destruction normal growth and formation of black ear tissue. Control methods: �� Crop rotation; �� seed treatment: 60cI = warm water soaking 10-20min, then placed in 3% of the bag wrapped in lime water for a 5% dip 2 ~ 3d, or equivalent Bordeaux soaking 24-72h. 2.5.2 leaf blight and sheath in Coix, the early yellow spots, yellow leaves expanding so. Control methods: rational close planting, pay attention to air and light; strengthen field management,[link widoczny dla zalogowanych], application of organic fertilizer to enhance plant disease resistance. 2.5.3 Corn Borer in Coix heading stage, the larvae bore into the stems Zhushi healthy tissue, causing more Mature larvae in corn stalks in the winter or Coix, 1a can occur in several generations to the first and third, took the most serious harm. Control methods: �� biological control: release Trichogramma and Beauveria bassiana. �� emergence in early spring before the corn the previous year Coix and maize straw to burn or soak into the fertilizer concentration to eliminate the Insect. �� with black light in the 5 to 8 month of trapping adults. �� timely removal of dead heart seedlings. �� Drug Control: with 50% fenitrothion EC 200 times filling the heart,[link widoczny dla zalogowanych], 50% can also be used 500 times Carbaryl powder spray, can also be used 50% of the particles filling the heart of carbaryl. 2.5.4, also known as burglary armyworm armyworm insects to larvae damage leaves, young stems and tender ear. Control Methods: In 50% of larval spraying dichlorvos 800 times; in adult liquid with sweet and sour (sugar, vinegar, white wine, water, the ratio of 3:4:1:2) trapping. 3 Coix seed harvest ripening time inconsistency, can be about 80% of grain in the fields change color when ripe harvest. Cut plants should focus on legislation put 34d after threshing, threshing seeds 2 to 3 after a sunny day of drying, seed moisture content of not more than l2% to storage when the storage. A 59 -
