Preparing the Field and Applying Base Fertilizers

The ginger root system is underdeveloped and its nutrient-absorbing ability is poor. So it cannot endure drought or waterlogging. The ginger field should be fertile, should have deep soil that is rich in organic substances, capable of retaining moisture and fertilizer, can be irrigated and drainedeasily, and isomewhat acidic. It is better to rotate crops for three to four years. It is not advisable to plant ginger continuously in the same plot; and the land becomes unfit for ginger planting at least for three to four years if the crop has been infected with blast.

Once the ginger field is selected, tillage should start in the autumn or winter after the previous crops have been harvested. Ploughing 25 to 30 cm deep promotes roots to extend to such a depth, and enlarges the absorption area. After the ground thaws out next year, harrow carefully once or twice, apply 75 to 120 t/ha high-grade manure and 750 to 1125 kg/ha calcium superphosphate, and then harrow the field flat carefully.

In the north of China, making ridge and planting in ditch is often being adopted. The ditch is in an east to west or south to north direction, and is about 25 to 30 cm deep. Farmers in the north often apply bean cake or cooked beans as fertilizer. In general, 1,125 to 1,500 kg/ha crushed cake or 750 to 1,125 kg/ha cooked and fermented bean is spread in the ditch (Figure 6.9). In addition, 225 kg (NH4) 2 SO4, 375 kg calcium superphosphate, and 150 kg K2SO4/ha are also used together as a basal application. Fertilizers are mixed with soil (Xizhen et al., 1997a).

There are more rains in the south of China, so high farmlands are usually used in ginger cultivation. The farmers always cover the seed rhizome with a layer of soil and 75 t/ha manure mixed together and then finally with 2 to 4 cm soil.

Planting

Preparation Before Planting: Ginger rhizomes are big, and there are several buds on each piece of rhizome. In order to select good seed and strong buds, we need to select buds and to break seed-rhizomes carefully into small pieces by hand. Usually, the bigger the seed, the earlier the seeds sprout, the more vigorous the seedlings grow, and the higher the yield. If seeds are too small, they will sprout later, the yield per plant will be decreased, the commercial quality will be poor, and the economic benefit will be
