Generally speaking, it is best to plant fruit corn in April, when the temperature is relatively cool, roughly between 15 and 26 degrees, which is suitable for seed germination. Another advantage of planting in spring is that there is plenty of rain, which will not rain often, and too much water is not conducive to its germination and growth.
Planting time of southern fruit corn: March-April and July-August can be used to plant southern fruit corn.
Planting time of northern fruit corn: When the ground temperature in the north is stable at about 15 degrees Celsius, it can be planted in March of the lunar calendar. If there is a greenhouse, it can also be planted in advance.
Fruit corn producing area
Fruit corn is also distributed in southern Peru, Chile, Argentina, Ecuador, Bolivia, Mexico and other regions. In China, it is mainly distributed in Yunnan-Guizhou Plateau and Guangxi in North China and Southwest China.
Method for plan fruit corn
Choose varieties with strong adaptability, disease resistance, high quality, high yield and high commodity value and plant them in soil with good irrigation and drainage, good uniformity and medium and high soil fertility. Base fertilizer can be applied to soil, mainly fully decomposed farmyard manure and appropriate compound fertilizer. After sowing, cover it with fine soil for about one centimeter, and then cover it with film to keep it warm and moist.
After emergence, remove the plastic film, strengthen the management of water and fertilizer, transplant the seedlings when they grow to 3-5 real leaves, control the planting density, ensure good air permeability, apply appropriate amount of farm manure to meet the growth needs, weed in time, water properly and do not accumulate water.
Key points of fruit and corn planting management
First, water scientifically.
After planting fruit corn, you can water it once, and then water it according to the dry humidity of the soil after slowing down the seedling stage. If the temperature is low, you can reduce the number of watering. If the temperature is high and the air is dry, you can water it once a day, or spray water to moisturize it, but you can't water it too much and there can be no water accumulation.
Second, intertillage weeding
After the slow seedling stage of fruit and corn, loosen the soil in time to enhance air permeability and drainage, prevent soil hardening from affecting root respiration and growth, pay attention to the depth of intertillage, and don't hurt roots. Weeding is best done manually or with mild herbicides.
Third, rational topdressing.
Before planting fruit and corn, sufficient base fertilizer should be applied. The fertilizer can be decomposed farmyard manure, and nitrogen fertilizer can be applied to promote its growth during the prosperous period.
Fourth, pest control.
Diseases and insect pests appear in the growth process of fruit corn, so it is necessary to weed in time, apply more phosphorus and potassium fertilizers, increase disease resistance and spray drugs in time.
