During a certain period of growth and development of corn, the growth and construction of roots, stems, leaves, ears, and grains have obvious primary and secondary relationships(propagation tray). According to morphological characteristics, in agricultural production, the growth cycle of corn is generally divided into three growth stages: seedling stage, ear stage, and flower stage(nursery plant pots). The period from corn planting to jointing is the seedling stage.

This stage includes the process of seed germination, emergence and seedling growth(plug trays). For example, under short light conditions, the average number of leaves per plant is reduced by 1.8 pieces during the daytime when the temperature is 21 ° C and 16 ° C at night; the effect of fertilization on leaf growth Fertilization is an important means for promoting the growth of leaves one(seed starter trays). The color of filigree is divided into green, red, brown and purple.
(large outdoor plastic plant pots wholesale nz)The stigma is the decentralized part of the top of the filigree(gallon nursery pots). Strong seedlings are the basis for high yields. The agricultural technical measures during sowing are to ensure that the seedlings are complete and lay the foundation for the seedlings to grow together(7 gallon nursery pots supplier). According to its morphological characteristics and growth properties, the growth and development of corn can be divided into different stages.
Maize germination of most people is closely related to the viability of the seeds themselves, the maturity of the seeds, the external conditions during the storage of the seeds, and the seed life(gallon plant pot). At the seedling stage, the root system is well developed, the leaves are thick, the leaves are flat and broad, the color of the seedlings is dark green(black plastic plant pots). Generally, the seeds are fully mature from the end of the wax maturity to the maturity period.
The seeds swelled with water and began to shade(cell trays). First, the radicle was born and tied down, and then the shoots emerged from the top soil. During the germination and emergence of seeds, the nutrients and energy required for root and leaf growth are supplied by the endosperm, so it is a heterotrophic process(14 gallon nursery pots supplier). Generally, low temperature and insufficient soil moisture are the main factors affecting germination and emergence.(large outdoor plastic plant pots wholesale nz)
The jointing to tasseling stage of corn is the main stage of root growth(square nursery pots). It can be seen that the amount of organic nutrients synthesized by the plant at the flowering stage and the grain holding capacity are the decisive factors for the economic output of corn(15 gallon nursery pots supplier). If they are stored and kept properly after harvest, they can still maintain a high germination capacity for 2 to 3 years, and the heart and leaves overlap.
The growth of maize seedlings is mainly differentiated roots, stems and leaves and other vegetative organs(plastic grow pots). During this period, the number of nodal root layers grown accounts for about 50% of the total nodal root layers, and the unfolded leaves account for more than 30% of the total leaves. The festival has been differentiated(gallon plant pots wholesale). Therefore, in terms of growth properties, the seedling stage belongs to the stage of vegetative growth.
(large outdoor plastic plant pots wholesale nz)During this period, the plant experienced a period of growth such as small trumpet, large trumpet, tasseling, etc(flat plastic tray). At the ear stage, the vegetative organs such as roots, stems, and leaves of corn grow vigorously, and the female and tassel reproductive organs also develop strongly(half gallon nursery pots wholesale). Generally, the number of hyperplastic joints is 3 to 5 layers, accounting for more than 50% of the total number of joints. Reach out and unfold.
