Seed planting method 1, seed planting time
The best planting time for trifle seeds is the spring and autumn seasons, with the most growthable temperature for seed cultivation ranging from 19 to 24°c, and in the spring, usually between the end of march and the end of april, when temperatures can be stabilized above 15°c. In mid-september, planting was usually done in the fall。
2. Soil formulation
The seedlings are small, the seedlings are thin, and the seedling period is extremely slow to grow, requiring deep tillage before planting, flattening the ground, tearing up the pieces of soil, and defusing and levelling the soil。
3. Seed leaching
Seeds should be impregnated before seed planting with 1. 5 kg water per kilogram of seed, plus 1 g of ammonium molyte impregnated for 12 hours, and seeded with 5-10 kg of phosphorous fattening or 5-10 kg of yellow sand。
4. Seed planting methods
Three-leave seeding methods are varied, and can be broadcasted either on a single basis or on a strip, with an artificial meadow acre planting 0. 4 to 0. 5 kg and a wet seeding depth of 1 to 2 cm, bearing in mind that if the seeding is too deep, it is not easily seeded。
Post-moderate management of trifle grass 1 land
The seedlings can be replanted in the autumn to restore grassland productivity if they break the slabs in time for the planting of the seedlings。
2. Weed removal
The three-leaved seedlings grow slowly and are vulnerable to weeds, which should be cultivated one to two times in the pine field and removed in time for two to three years after the formation of the grass cover。
3. Sufficient water
Three leaves are to be followed up with pine soil and calcium phosphate in the acre before the spring, fall and rebirth of the herd. 20-25 kg, irrigated when the soil is dry or combined with fertilizer。
4. Disease control
The trifle is less ill, but in time for harvest there are also cases of lignoplasm and powder disease, which can be used first and then treated with bordeaux, thiomers or polybacterials。
