Embodiment Construction

[0019] The present invention will be further described below in conjunction with the embodiment of " Huazhen " sweet corn.

[0020] This embodiment includes the following steps:

[0021] 1) Choose loose and fertile sandy loam soil and mix well with decomposed organic fertilizer in a ratio of 5:2, sterilize with chlorothalonazim, put it into a 128-hole tray after standing for 10 days.

[0022] 2) Lay a layer of film on the ground, place the hole trays filled with soil on the film in order, dry the seeds for 1 day before sowing, pour enough water on the prepared hole trays, and live broadcast the dried seeds at the rate of 1 grain / hole. Cover with 1-1.5cm thick fine soil, and then cover with a layer of film or sunshade net.

[0023] 3) When the seedlings have emerged, control the temperature at 17-24°C and the humidity at 62-68%; when the seedlings grow to 2 leaves and 1 heart, lift the plug tray, and the main root of the corn seedlings has grown out of the leakage ...

Abstract

The invention discloses a sweet corn lodging-resistance seedling raising and culturing method including steps of (1) applying fertilizer and preparing soil trays, (2) sowing seeds in the trays directly, (3) performing root excision after seedlings grow neatly, (4) performing ventilative acclimatization to the seedlings before transplanting, (5) planting green manure of vetch, (6) plowing the vetch into fields, and (7) transplanting, watering roots, ridging and then covering mulches. The method has the advantages of simplifying seedling raising and culturing processes, saving time and labor and the like, further, enabling roots of sweet corn to grow strongly, increasing growth speed of aerial roots, improving effective fertility of plant soil and soil permeability, reducing field weed effectively, improving quality of sweet corn effectively and increasing output by 15-20% as compared with that of the conventional culture method. By means of seedling root excision, soil humidity at roots is reduced, growth of lateral roots and aerial roots is accelerated, the root system total is increased by 10-25%, and thus, lodging resistance capacity of sweet corn is improved.

Description

technical field [0001] The invention relates to a method for continuously cropping and no-tillage cultivation of melons and fruits, in particular to a method for continuous cropping and no-tillage cultivation of melons, belonging to the technical field of plant cultivation. Background technique [0002] Sweet corn, also known as vegetable corn, is a sweet subspecies of corn. Sweet corn is favored by consumers from all walks of life because of its rich nutrition, sweetness, freshness, crispness, tenderness and glutinousness. It has high edible value and is widely used as a nutritious food for health care. [0003] Sweet corn lodging is the phenomenon that the stalk turns from upright to inverted due to external factors. Lodging is an important factor affecting the yield and quality of corn. According to statistics, lodging leads to a 15% to 25% reduction in corn yield. The yield loss of corn due to lodging in my country is nearly 1 million tons every year. At present, with ...
