High-yielding Cultivation Techniques of Maize

First, use dense-seed corn hybrids to promote the "two-crop intercropping" method for stable production: Intercropping varieties should have similar growth periods and basically the same plant height.
Second, when the time of early sowing: wheat harvest 2-3 days before the interplanting wheat ridge, or after the wheat harvest timely sowing.
Third, improve the quality of sowing, to Miao Qi Miao uniform: the width of the width of the planting (8040 cm) to be consistent; if the bottom squat, watering in time to ensure Miao Qi Miao uniform.
IV. Chemical weed control and pest control: Combine pesticides sprayed with herbicides, such as methyl isothiophos, to kill eggs and larvae that remain on wheat straw. Small bell-mouth period and big bell-mouth period lose heart with phoxim particles or killing dan granules, and prevent borer pests such as corn borer.
V. Check for leaks, reseeding and transplanting, and prevent the lack of seedlings.
Sixth, the seedlings, Dingmiao: dense planting varieties of seedlings per acre 4000-4500, thin-cultivated varieties of seedlings per acre 3300-3800 strains.
Seven, scientific fertilization: 1, kind of fertilizer: poor land plots, before sowing can be applied per acre of ammonium (or diammonium) 5-10 kg. 2. Miao Fei: Jointing period (25 days after sowing) Apply 15 kg of urea per mu, 10-15 kg of monoammonium (or diammonium), 1 kg of zinc fertilizer, 5 kg of potassium fertilizer, or 20-25 kg of corn formula fertilizer. 3, panicle fat: large bell mouth period (45 days after sowing), urea 20-25 kg per mu, potassium 5 kg; or 35-40 kg of corn formula fertilizer.
VIII. Scientific irrigation: Focus on pouring sowing water, pumping water and grouting water.
Nine, control and prevent fall: when the chemical control period is strictly controlled in 6-10 leaves, the dose should be accurate.
Ten, timely harvest: corn glutinous leaves from yellow to white, become loose, grain hard and shiny, harvested when the milk disappeared.

The selection and application of Lentinus edodes strains is a relatively complicated technical issue. In addition to understanding the quality standards of the strains, users need to understand the age of different strains from 55 to 240 days (the time difference from cultivation to mushrooming). Up to 2-6 months), mushroom shape and temperature type (sensible temperature of mushroom can be divided into low temperature type 8 ℃ ~ 12 ℃, medium temperature type 12 ℃ ~ 16 ℃, high temperature type 18 ℃ ~ 22 ℃, 12 years a year The monthly average temperature changes between 2 ° C and 4 ° C), combined with the basic knowledge of applied technology such as the seasoning of mushrooms, can only choose the suitable high-yield stable bacteria.
