Chives have the most pesticide residue at the roots; remove half an inch of the root and first soak them in lightly salted water.
1. Temperature management. Chives like cool conditions, with an optimum growing temperature of 15-24°C, and should be ventilated appropriately during the day. To promote sprouting, after covering with a plastic tunnel the daytime temperature should be kept at 18-25°C, and after sprouting the daytime temperature should be controlled at 17-23°C. Before harvesting the first cut of chives, the daytime temperature should be 15-22°C and the nighttime temperature 10-12°C. After that, with each cut...

Master the correct method when earthing up ginger to avoid damaging the roots
Ginger needs to be earthed up several times during its growth period. It is understood that the mechanical earthing-up machine used locally in Anqiu causes more serious root damage to ginger than manual earthing up, because the furrow bottom formed by the earthing-up machine is about 20 cm wide and the ridge height is 40 cm, while manual earthing up with a hoe leaves a furrow bottom of about 10 cm and a ridge height of around 35 cm. "When the earthing-up method cannot be changed, excessive root damage can be avoided by adjusting the growth direction of the underground ginger tubers, that is, when sowing the seed ginger, deliberately place the seed ginger perpendicular to the planting row, so that the daughter ginger and granddaughter ginger are also perpendicular to the planting row. By the time of earthing up, the entire ginger tuber is then perpendicular to the planting row, while the fleshy roots, lateral roots and fibrous roots caused by earthing up extend along the direction of the planting row, so they will not be damaged too much during earthing up. If the underground seed ginger is sown parallel to the planting row, too many roots will be damaged during earthing up." said Liu Shinian of Qianyulin, Linghe Town, Anqiu City.

Detailed Explanation of the Growth, Development and Functions of Rice Roots
After the seeds are pre-germinated, they sprout and grow roots. At first, only one root grows, called the seminal root (primary root), which develops from the radicle of the seed. The fibrous roots that later grow from the root primordia at the stem nodes are called adventitious roots. The coleoptile node and the incomplete leaf node produce about 5 roots, the first, second and third leaf nodes produce about 10 roots each, and the nodes above the fourth leaf position produce about 10 to 20 roots each. This is because the leaves increase in size in sequence from bottom to top, so the nutrients supplied for root growth increase in sequence, and the number of roots produced also increases. The nodes of the aboveground part generally do not produce roots. The nutrients produced by the leaves are
