1, select varieties

Selecting good varieties is the basis of high yield, but also for the season, early occupation of the market, the key to improve economic efficiency. Such as raw food-oriented, can choose the rhombus large early and medium maturity varieties (two-horned rhombus), phased in batches on the market.

To high-yield-oriented, can be planted late maturity of the Uling varieties. At the same time, because the rhombus caste is easy to degenerate, must pay attention to the choice of rhombus shape full, high degree of fullness, full hardening of the pericarp, no pests and diseases of the rhombus to stay in the seed.

2, timely and dense planting

Local stocking rhombus suitable time, generally before and after the Qingming Festival, the water temperature stabilized at 12 ℃ or more, can be divided into direct seeding and seedling transplantation of two kinds. Directly suitable for the depth of 2-3m, fertile subsoil of the pond, when the rhododendron germ grows 1 ~ 2cm, the rhododendron seed evenly spread in the water.

Before sowing, we should pay attention to clearing the river pond in the water grass, moss and wild diamonds, mu with the amount of seed is generally 10kg, poor fertility of the river pond can be appropriately increased with the amount of seed. For large water surface, deeper river ponds, seedling transplantation can be used. Choose a fertile subsoil, shallow river ponds, dry water before sowing sun hard topsoil, apply enough farmyard manure as a base fertilizer.

Seeds put shallow water, and later with the increase in the age of the seedlings gradually deepen the water layer, mu with the amount of seeds in about 60kg, can be transplanted to the surface of the water 5-6 acres. Seedling age in about 60 days, there are 10 pieces of top leaves, diamond plate in 15cm, with 2-3 branches when stocking.

The stocking with grass rope 10 plants tied into a bundle, gradually inserted into the bottom of the water. Rhombus grows out of the water such as density is too high, you can take artificial thinning and even seedlings, to prevent the diamond head early sealing of the water surface and open the disk is small, affecting the yield.
