I. High-yield corn cultivation techniques
1, site preparation as soon as possible to plow, give enough farmhouse manure 1000-1500 kg per mu, in order to mature the soil, the bottom of the savings, the spring and then arable land, to turn, rake, pressure and other farming links closely, pay attention to security.
2. Luodan No. 9 was selected as a model corn variety and the whole growth period was 120-125 days, the plant height was 272.5 cm, the ear height was 107.8 cm, stem diameter was 2.14 cm, the plant type was half covered, and the spike length was 18 cm. The number of rows is 12 rows, the number of rows is 38.5 grains, the grain weight is 410.4 grams, the seed rate is 80.2 inches, the grain is pure white, the dentition type, resistance to spot disease, head smut, and resistance to lodging. Adapt to 800-1400 meters above sea level.
3. Reasonably dense planting corn adopts wide and narrow rows of sowing methods, of which the big line is 120 centimeters, the small line is 60 centimeters, the spacing between plants is 40 centimeters, and the average is 3500-3700 strains per acre.
4. Fertilization principles for fertilization in the field are as follows: Lightly applying Miaofei and reapplying loosing fertilizer. When planting, it requires 1000-1500 kg per hectare of decomposed farmyard fertilizer, 5 kg of urea per mu, 20 kg of compound fertilizer, 40 kg of general calcium, 3 kg of potassium dihydrogen phosphate, and basal fertilizer in Shitang (groove). 5-6 leaves Mushi 8-10 kg urea fertilizer. Corn attacking panicle fertilizer in the big bell-mouth period, grab a good weather re-apply, this fertilization is the most critical part of high-yield corn, mu Shi 15 kg urea, and then timely cover fertilizer.
5. Field management seedling stage with 2.5% deltamethrin EC per acre 20 ml water 50 kg prevention and control of ground tiger; large bell season combined with cultivator soil for weeding, mu with 3.6% pesticidal double granules 1 kg snacks to prevent corn borer To observe at any time before jointing until maturity, once the pests are found, choose the medicine in time to prevent and control.
Second, dwarf beans intercropping techniques
1. Collaborative sowing dwarf beans and corn should be sown at the same time.
2. Planting specifications (1), interplanting 1 row of dwarf beans within a large row of corn, 30 cm from the pond, 50 cm between dwarf beans and corn, 2-3 grains per pond, (2), interplanting 2 rows of dwarf beans within a large row, 30 rows apart In centimeters, the distance between the ponds is 30 cm, and the distance between dwarf beans and corn is 30 cm. Each pond has 2-3 capsules to ensure Miao Qi.
3. Scientific fertilization When sowing, apply 2-3 kg of compound fertilizer per acre. When fertilizing, avoid direct contact between seeds and chemical fertilizers. Before the 3rd leaf stage after emergence, must apply 3-5 kg ​​of compound fertilizer in time, but avoid that the fertilizer adheres to the bean leaf, otherwise the phenomenon of burning seedling will occur. Flowering 5-7 days Mushi compound fertilizer 2-4 kg for flower manure.
4. Field management should be conducted with time seedlings, seedling reseeding, deep loosening and weeding, and prevention of pests and diseases.
5. Timely harvest When the field's petioles have fallen from 70 to 80 degrees, it is the best time for artificial harvesting.
III. Xiaomi cuisine technology
1. Choose color varieties with good taste, high yield and strong resistance.
2. Soil fertility After harvesting dwarf beans, deep plowing 15 cm to 20 cm, combined with deep plowing 1500 kg per acre Shinong manure as a basal, and then do width 80 centimeters to 100 centimeters.
3. timely sowing
Seeds can be sown in late October. Before sowing, sufficient water should be poured. Seeds should be 3-4 kilograms per acre. Seeds should be mixed with appropriate amount of fine sand and spread on the surface. Cover with fine soil.
4. Strengthen the management of cotyledons unearthed after the first field weeding and spawning, grow 2 true leaves and then the second weeding and seedlings, and top-dressing watering, generally mu compound fertilizer 10 kg, every 15 days combined with watering Apply 5 kg of compound fertilizer. After each harvest, topdressing water once.
5. Timely harvest of millet dishes to 4-6 leaves, plant height 10 cm -15 cm can be listed between big seedlings.
1, site preparation as soon as possible to plow, give enough farmhouse manure 1000-1500 kg per mu, in order to mature the soil, the bottom of the savings, the spring and then arable land, to turn, rake, pressure and other farming links closely, pay attention to security.
