How should lotus roots be fattened?

è—• Suitable for growing in hot and rainy seasons. Most of the south of the Yangtze River was planted in the first three months of March, and the Beijing area was planted in the first half of May. Putian chooses slightly acidic or near-neutral clay soil with rich soil and abundant organic matter. The cockroach must have a female cockroach with full traits, fullness of the hoe, complete buds, hypertrophy, small stalks, thick fat and bright color, or fully mature scorpions. The sowing method should be followed by digging, on-demand, and planting, and it is also feasible to plant after germination. Putian generally maintains 5-6cm of shallow water in the early stage, promotes germination and leafing, and the water depth is 15-16cm in the middle stage; then put shallow water in the later stage to facilitate crusting.

During the growth process, oxygen in the air combines with iron in the soil to form red-brown rust spots of ferric oxide, which are attached to the epidermis. When the lotus leaves withered, the respiration of the cockroaches slowed down, and the rust spots gradually decreased due to the reduction. Therefore, the leaves are picked before harvesting, and the rust spots are easily washed away. The umbilicus, petioles and underground stems are connected by aerated tissue, so the petioles cannot be broken to prevent the plants from rot.

Lotus root fattening skills:

The nutrients needed for lotus root growth and development come from the photosynthesis of lotus leaves; on the other hand, they come from the soil, while the original fertilizer in the soil is limited (including the base fertilizer), which will grow with the growth of the plants. Less, although the fish's feces and residual bait can provide a certain amount of nutrients for the alfalfa, it is rare compared to the growth requirement of alfalfa, so it is necessary to topdress in time.

Lotus roots have a long growth period and are generally topdressed 2-3 times. For the first time, when the lobes began to appear, after cultivating and weeding, 750-1000 kg of human excrement was applied per 667 square meters. The second top dressing was carried out when there were 5-6 pieces of the lobes, and about 1000 kg of human excrement was applied per 667 square meters. The third top dressing is carried out at the end of the emergence of the leaves, when the crusting begins, called the chasing fat. Each 667 square meters of manure and urine fertilizer 1500 kg, cake fertilizer 30-50 kg.

Fertilization should be chosen in sunny and windless weather, avoiding the noon in the hot sun. The field water is drained before each fertilization, so that the fertilizer is sucked into the water and then re-irrigated to the original depth. In the deep-water paddy field, the fertilizer is easily lost, and the liquid fertilizer cannot be directly applied. The method of applying the fertilizer should be adopted. That is, heavy fertilizer is applied and buried in the mud. When using fertilizer for top dressing, first mix the chemical fertilizer with the river mud to make a fat mud group and then apply it to Putian.
