With the development of farmland water conservancy construction(2 gallon nursery pots wholesale), the standard nitrogen fertilizer consumption per acre is about 80 to 100 kg in high-yield corn areas and about 40 to 60 kg in low- and medium-yield areas. However, the amount of phosphate and potassium fertilizers is relatively small. Organic fertilizers are usually applied as base fertilizers(4 gallon planter). Chemical fertilizers are mostly used as top dressing.

The basic principle of fertilization is based on basic fertilizers, supplemented with topdressing; supplemented with organic fertilizers, supplemented with chemical fertilizer(14 gallon nursery pots wholesale)s; supplemented with nitrogen fertilizers, supplemented with phosphorus and potassium fertilizers; supplemented with tapping fertilizers and supplementing with grain fertilizers(five gallon pot). The annual rainfall is 1000-1800 mm, and the distribution is relatively uniform.(high quality plastic 72 cell trays manufacturers russia)
This area belongs to subtropical and tropical humid climate, with high temperature, abundant rainfall, and little frost and snow(15 cell propagation trays wholesale). The days suitable for the growth of crops are 220-360 days, and the effective temperature accumulation time for corn growth and development is more than 250 days(white plastic hanging baskets). The annual sunshine is 1600-2500 hours, the annual radiation is 103-136 kcal per square centimeter, and corn can be grown all year round.
Due to the high rainfall and humid climate in this area, the yield of rice planting is relatively high, and the corn planting area not only changes greatly, but also the output is very unstable(21 cell propagation trays wholesale). Spring maize and summer maize are only planted on the hilly dry land(2 gallon pots distributor). Corn in this area is planted all seasons, and multi-cultivation cultivation is extremely popular, from two-crop a year to three-crop and four-crop a year, but mainly used as autumn or winter crops.
(high quality plastic 72 cell trays manufacturers russia)Winter corn is mainly distributed in the southern regions of Guangdong(32 cell propagation trays wholesale), Guangxi, Fujian and other provinces (regions). The mid-season rice is transplanted immediately after harvest, which can strive for 3 to 5 days of agricultural time and accumulated temperature(3 gallon pots distributor). This area includes all of Xinjiang and the Hexi Corridor in Gansu (north of Qilian Mountain and south of Dasha River). The main planting area of winter corn.
In the 1960s, it developed into a maize winter sowing breeding and improved seed breeding base(50 cell propagation trays wholesale). In the 1970s, it developed into a fixed crop in the multi-cropping system in some areas. Have a certain position in the rotation. This area has a continental dry climate with very little precipitation, and no corn has been planted in the past(2 gallon pots wholesale). The frost-free period in this area is 130 to 180 days, and some areas are around 200 days.
In order to fight for the agricultural season, autumn corn in Zhejiang, Jiangxi, Hunan and other provinces often uses pond mud seedlings or nutritious sports seedlings(98 cell propagation trays wholesale). Production has an important role(2.5 inch square plastic pots). However, the soil is mostly red soil and yellow soil, with low fertility, heavy soil erosion, and uneven agricultural production development, especially in land use, there is a tendency for heavy paddy fields to lighten early fields.(high quality plastic 72 cell trays manufacturers russia)
There is still great potential for planting green manure, improving fertility, expanding corn in dry hilly areas, and increasing yield(105 cell propagation trays wholesale). Due to the frequent waterlogging in early spring and summer and insufficient heat resources in the area, the northern region gradually changed to interplanting corn after the 1970s, but in recent years, with the improvement of fertilizer and water conditions and the improvement of agricultural mechanization, it has developed slightly(plastic bonsai pots wholesale).
